Raw Blame History

4.0.0 (unreleased)

Introduction

This version introduces many breaking changes, which in most projects can be managed through a combination of automatic upgrade processes as well as manual code review. This document reviews these changes and will guide developers in preparing existing 3.x code for compatibility with 4.0

Highlights of major changes

Minimum version dependencies have increased; PHP 5.5 and Internet Explorer 10 (or other modern browser) is required.
All code earlier marked as deprecated for 4.0 has now been removed. See deprecation documentation for information on code deprecation.
All SilverStripe classes are now namespaced, and some have been renamed. This has major implications for arrangement of templates, as well as other references to classes via string literals or configuration. Automatic upgrading tools have been developed to cope with the bulk of these changes (see upgrading notes).
Object class has been removed.
Asset storage has been abstracted, and a new concept of DBFile references via database column references now exists in addition to references via the existing File dataobject. File security and protected files are now a core feature.
A new front-end development process has been developed for the construction of javascript based components, prominently featuring ReactJS to develop highly functional CMS content areas. A new standard form schema API has been developed to allow back-end PHP constructed forms to scaffold themselves within ReactJS powered sections.
CMS CSS has been re-developed using bootstrap 4 as a base (blog post)
Asset admin has been replaced with a purely ReactJS powered upgrade, and split out module called asset-admin. You'll need to add this to your composer.json to retain file management capabilities for your CMS authors.
Versioning is now a much more powerful feature, with the addition of campaigns to allow batches of related or inter-dependent objects to be published as a single act. Dependencies between versioned objects can be declared using the new ownership API, so that developers can ensure that relational consistency is maintained during publishing. This new system can be managed via the new "Campaigns" CMS section (blog post)
Template variable casting (e.g. <h1>$Title</h1>) is enforced by default, which will ensure safe HTML encode unless explicitly opted out.
Themes are now configured to cascade, where you can specify a list of themes, and have the template engine search programatically through a prioritised list when resolving template and CSS file paths.
i18n Updated to use symfony/translation over zend Framework 1. Zend_Translate has been removed.
Replaced Zend_Cache and the Cache API with a PSR-16 implementation (symfony/cache)
_ss_environment.php files have been removed in favour of .env and "real" environment variables.
admin has been moved to a new module silverstripe/admin.
Behat support updated to behat 3. See the behat extension for more information.

Upgrading

The below sections describe how to go about updating an existing site to be prepared for upgrade to 4.0. Most of these upgrading tasks will involve manual code review, although in some cases there are some automated processes that users can run to

Standard Upgrade

This section describes the processes which every project upgrading to 4.0 should follow. This should be followed as a standard first point of upgrade.

Upgrade references to renamed and namespaced classes

Nearly all core PHP classes have been namespaced. For example, DataObject is now called SilverStripe\ORM\DataObject. We have developed an upgrader tool to (semi-)automatically update your 3.x code to the new naming. Here's an example how to upgrade your mysite folder:

composer global require silverstripe/upgrader
cd ~/Project/Root
~/.composer/vendor/bin/upgrade-code upgrade ./mysite --write

If you want to do a dry-run, omit the --write option to see a preview of a diff of all changed project files.

This will resolve the majority of upgrading work, but we strongly recommend reviewing the diff running some regression testing on your functionality. SilverStripe core classes can be referenced in your PHP files, but also in YAML configuration and SilverStripe templates. For a full list of renamed classes, check the .upgrade.yml definitions in each module.

The rename won't affect class-based permission codes or database table names.

Upgrade template locations and references

Templates are now much more strict about their locations. You can no longer put a template in an arbitrary folder and have it be found. Case is now also checked on case-sensitive filesystems.

Either include the folder in the template name (renderWith('MyEmail.ss') => renderWith('emails/MyEmail.ss')), move the template into the correct directory, or both. This also affects <% include %> statements in templates.

When using <% include %> template tag you should continue to leave out the Includes folder. <% include Sidebar %> will match only match Includes/Sidebar.ss, not Sidebar.ss. Please refer to our template syntax for details.

Core template locations have moved - if you're including or overriding these (e.g. for FormField templates) please adjust to the new paths. The forms folder no longer exists, and instead template locations will be placed in paths that match the SilverStripe\Forms namespace.

API Specific Upgrades

The below sections deal with upgrades to specific parts of various API. Projects which rely on certain API should be upgraded as appropriate using any of the relevant processes documented below.

Upgrade `mysite/_config.php`

The globals $database and $databaseConfig are deprecated. You should upgrade your site _config.php files to use the .env configuration (below).

If you need to configure database details in PHP, use the new DB::setConfig() api instead.

You should remove any references to ConfigureFromEnv.php in your project, as this file is no longer necessary.

Upgrade of `_ss_environment.php` to `.env` configuration

The php configuration _ss_environment.php file has been replaced in favour of a non-executable .env file, which follows a syntax similar to an .ini file for key/value pair assignment. Like the old php file, .env may be placed in either the web root, or one level above.

For example, if you have the below _ss_environment.php file, your .env would be rewritten as follows:

_ss_environment.php:

:::php
<?php
// Environment
define('SS_ENVIRONMENT_TYPE', 'dev');
define('SS_DEFAULT_ADMIN_USERNAME', 'admin');
define('SS_DEFAULT_ADMIN_PASSWORD', 'password');
$_FILE_TO_URL_MAPPING[__DIR__] = 'http://localhost';
// Database
define('SS_DATABASE_CHOOSE_NAME', true);
define('SS_DATABASE_CLASS', 'MySQLDatabase');
define('SS_DATABASE_USERNAME', 'root')
define('SS_DATABASE_PASSWORD', '');
define('SS_DATABASE_SERVER', '127.0.0.1');

.env:

## Environment
SS_ENVIRONMENT_TYPE="dev"
SS_DEFAULT_ADMIN_USERNAME="admin"
SS_DEFAULT_ADMIN_PASSWORD="password"
SS_BASE_URL="http://localhost/"

### Database
SS_DATABASE_CHOOSE_NAME="true"
SS_DATABASE_CLASS="MySQLDatabase"
SS_DATABASE_USERNAME="root"
SS_DATABASE_PASSWORD=""
SS_DATABASE_SERVER="127.0.0.1"

The removal of the _ss_environment.php file means that conditional logic is no longer available in the environment variable set-up process. This generally encouraged bad practice and should be avoided. If you still require conditional logic early in the bootstrap, this is best placed in the _config.php files.

Note also that $_FILE_TO_URL_MAPPING has been removed and replaced with SS_BASE_URL env var.

The global values $database and $databaseConfig have been deprecated, as has ConfigureFromEnv.php which is no longer necessary.

See Environment Management docs for full details.

Replace usages of Object class

Object has been superseded by a trio of traits which replace components of this legacy class:

Injectable: Provides MyClass::create() and MyClass::singleton()
Configurable: Provides MyClass::config()
Extensible: Provides all methods related to extensions (E.g. add_extension()). Note: All classes which use this trait MUST invoke constructExtensions() in its constructor.

In particular specific Object class usages should be replaced as below:

Upgrade subclasses

:::php
// old
class MyClass extends Object {}
// new
class MyClass {
    use Extensible;
    use Injectable;
    use Configurable;
    
    public function __construct() {
        // Only needed if using Extensible trait
        $this->constructExtensions();
    }
}

References to $this->class

:::php
// old
$obj->class
$this->class;
// new
get_class($obj);
static::class;

Upgrade parse_class_spec()

:::php
// old
$spec = Object::parse_class_spec($spec);
// new
$spec = ClassInfo::parse_class_spec($spec);

Upgrade create_from_string()

:::php
// old
$obj = Object::create_from_string('Varchar(100)');
// new
$obj = Injector::inst()->create('Varchar(100)');

Extensions

:::php
// old
Object::add_extension('File', 'Versioned');
$has = Object::has_extension('File', 'Versioned');
$extensions = Object::get_extensions('File');
// new
File::add_extension(Versioned::class);
$has = File::has_extension(Versioned::class)
$extensions = File::get_extensions();

// new (alternate form)
// Note: The class the extension method is called on MUST be a parent class
// of the first argument.
DataObject::add_extension(File::class, Versioned::class); // alternate
$has = DataObject::has_extension(File::class, Versioned::class); // alternate
$extensions = DataObject::get_extensions(File::class);

Upgrade references to Session object

Session object is no longer statically accessible via Session::inst(). Instead, Session is a member of the current request.

Before:

:::php
public function httpSubmission($data, $form, $request) {
    Session::set('loggedIn', null);
}

After:

:::php
public function httpSubmission($data, $form, $request) {
    $request->getSession()->set('loggedIn', null);
}

In some places it may still be necessary to access the session object where no request is available. In rare cases it is still possible to access the request of the current controller via Controller::curr()->getRequest() to gain access to the current session.

Compatibility with the new front-end building tools

If you are using Requirements from 3.x then your scripts should continue to work as they did before. The new front-end tooling is intended only for those wishing to customise the CMS look and feel, or behaviour.

Those wishing to customise the CMS should read about how to customise the admin interface.

Upgrade static references to asset paths

All static files (images, javascript, stylesheets, fonts) used for the CMS and forms interfaces in framework and cms have moved locations. These assets are now placed in a client/ subfolder, to account for a structural change where both javascript and styles are co-located in component-specific folders. This will affect you if you have used Requirements::block() on files in the framework/ or cms/ folder. Care should also be taken when referencing images in these folders from your own stylesheets (url()), or via SilverStripe templates (<img> tags).

Requirements now throws an exception then a file is not found, rather than failing silently, so check your Requirements are pointing to files that exist.

framework/javascript       => silverstripe-admin/client/dist/
framework/javascript/lang  => silverstripe-admin/client/lang/
framework/images           => silverstripe-admin/client/dist/images/
framework/css              => silverstripe-admin/client/dist/css/
framework/scss             => silverstripe-admin/client/src/styles/
admin/javascript/          => silverstripe-admin/client/src/
admin/javascript/src/      => silverstripe-admin/client/src/legacy/ (mostly)
admin/javascript/lang/     => silverstripe-admin/client/lang/
admin/scss/                => silverstripe-admin/client/styles/legacy/
admin/css/                 => silverstripe-admin/client/dist/css/
admin/css/screen.css       => silverstripe-admin/client/dist/css/bundle.css
admin/images/              => silverstripe-admin/client/dist/images/
admin/images/sprites/src/  => silverstripe-admin/client/src/sprites/
admin/images/sprites/dist/ => silverstripe-admin/client/dist/sprites/
admin/font/                => silverstripe-admin/client/dist/font/

Most JavaScript files in framework/javascript have been removed, and are bundled through Webpack into a combined file instead. If you have referenced these files elsewhere, please consider running the ES6 source files in admin/client/src/legacy through your own transpiling and bundle process.

This also includes JavaScript i18n support, and the removal of the i18n::js_i18n configuration option used in Requirements::add_i18n_javascript().

SilverStripe core is moving away from Requirements::combine_files in favour of Webpack as of 4.0. Requirements::combine_files is being considered for deprecation in future versions.

All JavaScript thirdparty dependencies have either been moved to NPM (see package.json), or moved into the framework/admin/thirdparty folder. If you are hotlinking to any of these files, please consider packaging your own versions in your projects and modules. For CMS modules, you can also use many library globals which the core bundles already expose (see Build Tooling).

One commonly linked thirdparty dependency is jquery.js bundled with SilverStripe:

framework/thirdparty/jquery/jquery.js => framework/admin/thirdparty/jquery/jquery.js

Explicit text casting is now enforced on all template variables

Now whenever a $Variable is used in a template, regardless of whether any casts or methods are suffixed to the reference, it will be cast to either an explicit DBField for that field, or the value declared by the default_cast on the parent object.

The default value of default_cast is Text, meaning that now many cases where a field was left un-uncoded, this will now be safely encoded via Convert::raw2xml. In cases where un-cast fields were used to place raw HTML into templates, this will now encode this until explicitly cast for that field.

You can resolve this in your model by adding an explicit cast to HTML for those fields.

Before:

class MyObject extends ViewableData {
	public function getSomeHTML {
		$title = Convert::raw2xml($this->Title);
		return "<h1>{$title}</h1>";
	}
}

After:

class MyObject extends ViewableData
{
	private static $casting = [
		'SomeHTML' => 'HTMLText'
	];

	public function getSomeHTML
    {
		$title = Convert::raw2xml($this->Title);
		return "<h1>{$title}</h1>";
	}
}

If you need to encode a field (such as HTMLText) for use in html attributes, use .ATT instead, or if used in an actual XML file use .CDATA (see template casting).

Upgrade code that uses SQLQuery

Where your code once used SQLQuery you should now use SQLSelect in all cases, as this has been removed (check the 3.2.0 upgrading notes).

Upgrade code that uses UploadField

This field has been superceded by a new class provided by the asset-admin module, which provides a more streamlined simpler mechanism for uploading File dataobjects.

A helper service FileHandleField is provided to assist with dependency injection. Where the asset-admin module is not installed this service will fall back to the FileField class instead.

Usages of UploadField will need to be upgraded as below:

3.x code

:::php
class MyClass extends DataObject {
    public function getCMSFields() {
        return new FieldList(
            new UploadField('Files')
        );
    }
}

4.x code

:::php
use SilverStripe\ORM\DataObject;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\FileHandleField;

class MyClass extends DataObject {
    public function getCMSFields() {
        return FieldList::create(
            Injector::inst()->create(FileHandleField::class, 'Files')
        );
    }
}

Upgrade code that uses i18n

In many cases, localisation strings which worked in 3.x will continue to work in 4.0, however certain patterns have been deprecated and will be removed in 5.0. These include:

_t calls with sprintf-style placeholders (%s). Replace with named placeholders instead.
_t calls with non-associative injection arguments. Please use an associative array for all arguments.
_t calls which do not include a default value will now raise a warning. This can be disabled by setting the i18n.missing_default_warning config to false.

Note: If you attempt to use non-associative injection arguments with named placeholders, the result will now trigger an exception.

Implementors of i18nEntityProvider should note that the return type for provideI18nEntities() has changed as well. The non-associative array return type is deprecated. If returning a default string for a module other than itself, it should return an array with the default and module keys respectively.

Full locale-rule respecting localisation for plural forms is now supported. The default key for an object plural form is <Namespaced\ClassName>.PLURALS, and follows CLDR array form for each pluralisation. See the CLDR chart for reference.

The below demonstrates how you can provide new localisation strings for an object, including both plurals and cross-module localisations.

:::php
class MyObject extends DataObject, implements i18nEntityProvider
{
    public function provideI18nEntities()
    {
        return [
            'MyObject.SINGULAR_NAME' => 'object',
            'MyObject.PLURAL_NAME' => 'objects',
            'MyObject.PLURALS' => [
                'one' => 'An object',
                'other' => '{count} objects',
            ],
            'AnotherSection.DESCRIPTION' => [
                'default' => 'This is the description for this section',
                'module' => 'extendedmodule',
            ],
        ];
    }
}

In YML format this will be expressed as the below:

mymodule/lang/en.yml:

:::yaml
en:
  MyObject:
    SINGULAR_NAME: 'object'
    PLURAL_NAME: 'objects'
    PLURALS:
      one: 'An object',
      other: '{count} objects'

extendedmodule/lang/en.yml:

:::yaml
en:
  AnotherSection:
    DESCRIPTION: 'This is the description for this section'

Usage of these pluralised strings is through the existing _t() method, and require a | pipe-delimeter with a {count} argument.

:::php
public function pluralise($count)
{
    return _t('MyObject.PLURALS', 'An object|{count} objects', [ 'count' => $count ]);
}

In templates this can also be invoked as below:

:::ss
<%t MyObject.PLURALS 'An item|{count} items' count=$Count %>

Removed Member.DateFormat and Member.TimeFormat database settings

We're using native HTML5 date and time pickers in DateField and TimeField now (discussion), where the browser localises the output based on the browser/system preferences. In this context it no longer makes sense to give users control over their own date and time formats in their CMS profile. Consequently, we've also removed MemberDatetimeOptionsetField.

Member->getDateFormat() and Member->getTimeFormat() still exist, and default to the IntlDateFormatter defaults for the selected locale.

New asset storage mechanism

File system has been abstracted into an abstract interface. By default, the out of the box filesystem uses Flysystem with a local storage mechanism (under the assets directory).

Because the filesystem now uses the sha1 of file contents in order to version multiple versions under the same filename, the default storage paths in 4.0 will not be the same as in 3.

In order to retain existing file paths in line with framework version 3 you should set the \SilverStripe\Filesystem\Flysystem\FlysystemAssetStore.legacy_paths config to true. Note that this will not allow you to utilise certain file versioning features in 4.0.

SilverStripe\Filesystem\Flysystem\FlysystemAssetStore:
  legacy_paths: true

See our "File Management" guide for more information.

Migrating File DataObject from 3.x to 4.0

Since the structure of File dataobjects has changed, a new task MigrateFileTask has been added to assist in migration of legacy files. Migration can be invoked by either this task, or can be configured to automatically run during dev build by setting the File.migrate_legacy_file config to true. However, it's recommended that this task is run manually during an explicit migration process, as this process could potentially consume large amounts of memory and run for an extended time.

File:
  migrate_legacy_file: true

This task will also support migration of existing File DataObjects to file versioning. Any pre-existing File DataObjects will be automatically published to the live stage, to ensure that previously visible assets remain visible to the public site.

If additional security or visibility rules should be applied to File dataobjects, then make sure to correctly extend canView via extensions.

Note that pre-existing security solutions for 3.x (such as secure assets module) are incompatible with core file security.

Upgrade code which acts on `Image`

As all image-specific manipulations has been refactored from Image into an ImageManipulations trait, which is applied to both File and DBFile. These both implement a common interface AssetContainer, which has the getIsImage() method. In some cases, it may be preferable to invoke this method to detect if the asset is an image or not, rather than checking the subclass, as the asset may also be a DBFile with an image filter applied, rather than an instance of the Image dataobject.

In addition, a new file category image/supported has been added, which is a subset of the image category. This is the subset of all image types which may be assigned to the [api:Image] dataobject, and may have manipulations applied to it. This should be used as the file type restriction on any [api:UploadField] which is intended to upload images for manipulation.

Before:

if($file instanceof Image) {
	$upload = new UploadField();
	$upload->setAllowedFileCategories('image');
}

After:

if ($file->getIsImage()) {
	$upload = new UploadField();
	$upload->setAllowedFileCategories('image/supported');
}

In cases where image-only assets may be assigned to relationships then your datamodel should specify explicitly an Image datatype, or refer to DBFile('image/supported').

E.g.

class MyObject extends DataObject
{
	private static $has_one = array(
		"ImageObject" => "Image"
	);
	private static $db = array(
		"ImageField" => "DBFile('image/supported')"
	);
}

Upgrading code that writes to `File` dataobjects, or writes files to the 'assets' folder

In the past all that was necessary to write a File DataObject to the database was to ensure a physical file existed in the assets folder, and that the Filename of the DataObject was set to the same location.

Since the storage of physical files is no longer a standard location, it's necessary to delegate the writing of such files to the asset persistence layer. As a wrapper for an individual file, you can use any of the setFrom* methods to assign content from a local (e.g. temporary) file, a stream, or a string of content. You would need to upgrade your code as below.

Before:

function importTempFile($tmp) {
	copy($tmp, ASSETS_PATH . '/imported/' . basename($tmp));
	$file = new File();
	$file->setFilename('assets/imported/'.basename($tmp));
	$file->write();
}

After:

public function importTempFile($tmp)
{
    Versioned::reading_stage('Stage');
    $file = new File();
    $file->setFromLocalFile($tmp, 'imported/' . basename($tmp));
	$file->write();
	$file->doPublish();
}

Note that 'assets' is no longer present in the new code, and the path beneath what was once assets is now used to generate the 'filename' value. This is because there is no longer an assumption that files are stored in the assets folder.

There are other important considerations in working with File dataobjects which differ from legacy:

File synchronisation is no longer automatic. This is due to the fact that there is no longer a 1-to-1 relationship between physical files and File DataObjects.
Folder DataObjects are now purely logical DataObjects, and perform no actual filesystem folder creation on write.
All Files are versioned, which means that by default, new File records will not be visibile to the public site. You will need to make sure to invoke ->doPublish() on any File DataObject you wish visitors to be able to see.

You can disable File versioning by adding the following to your _config.php

File::remove_extension('Versioned');

Upgrading code performs custom image manipulations

As file storage and handling has been refactored into the abstract interface, many other components which were once specific to Image.php have now been moved into a shared ImageManipulation trait. Manipulations of file content, which are used to generate what are now called "variants" of assets, is now a generic api available to both File and DBFile classes through this trait.

Custom manipulations, applied via extensions, must be modified to use the new API. For instance, code which sizes images to a fixed width should be updated as below:

Before:

// in MyImageExtension.php
class MyImageExtension extends DataExtension
{
	public function GalleryThumbnail($height)
    {
		return $this->getFormattedImage('GalleryThumbnail', $height);
	}

	public function generateGalleryThumbnail(Image_Backend $backend, $height)
    {
		return $backend->paddedResize(300, $height);
	}
}

// in _config.php
Image::add_extension('MyImageExtension');

Now image manipulations are implemented with a single method via a callback generator:

// in MyImageExtension.php
class MyImageExtension extends Extension
{
	public function GalleryThumbnail($height)
    {
		// Generates the manipulation key
		$variant = $this->owner->variantName(__FUNCTION__, $height);

		// Instruct the backend to search for an existing variant with this key,
		// and include a callback used to generate this image if it doesn't exist
		return $this->owner->manipulateImage($variant, function (Image_Backend $backend) use ($height) {
			return $backend->paddedResize(300, $height);
		});
	}
}

// in _config.php
File::add_extension('MyImageExtension');
\SilverStripe\Filesystem\Storage\DBFile::add_extension('MyImageExtension');

There are a few differences in this new API:

The extension is no longer specific to DataObjects, so it uses the generic Extension class instead of DataExtension
This extension is added to both DBFile and File, or order to make this manipulation available to non-dataobject file references as well, but it could be applied to either independently.
A helper method variantName is invoked in order to help generate a unique variant key. Custom code may use another generation mechanism.
Non-image files may also have manipulations, however the specific manipulateImage should not be used in this case. A generic manipulate method may be used, although the callback for this method both is given, and should return, an AssetStore instance and file tuple (Filename, Hash, and Variant) rather than an Image_Backend.

Upgrading code that uses composite db fields.

The CompositeDBField interface has been replaced with an abstract class, DBComposite. In many cases, custom code that handled saving of content into composite fields can be removed, as it is now handled by the base class.

The below describes the minimum amount of effort required to implement a composite DB field.

<?php
class MyAddressField extends DBComposite
{
	private static $composite_db = array(
		'Street' => 'Varchar(200)',
		'Suburb' => 'Varchar(100)',
		'City' => 'Varchar(100)',
		'Country' => 'Varchar(100)'
	);

	public function scaffoldFormField($title = null)
    {
		new AddressFormField($this->getName(), $title);
	}
}

Upgrading code that references `DataObject::database_fields` or `DataObject::db`

These methods have been updated to include base fields (such as ID, ClassName, Created, and LastEdited), as well as composite DB fields.

DataObject::database_fields does not have a second parameter anymore, and can be called directly on an object or class. E.g. Member::database_fields(). If user code requires the list of fields excluding base fields, then use custom_database_fields instead, or make sure to call unset($fields['ID']); if this field should be excluded.

DataObject:db() will return all logical fields, including foreign key ids and composite DB Fields, alongside any child fields of these composites. This method can now take a second parameter $includesTable, which when set to true (with a field name as the first parameter), will also include the table prefix in Table.ClassName(args) format.

Upgrade code that uses SQLQuery

SQLQuery is still implemented, but now extends the new SQLSelect class and has some methods deprecated. Previously this class was used for both selecting and deleting, but these have been superceded by the specialised SQLSelect and SQLDelete classes.

Take care for any code or functions which expect an object of type SQLQuery, as these references should be replaced with SQLSelect. Legacy code which generates SQLQuery can still communicate with new code that expects SQLSelect as it is a subclass of SQLSelect, but the inverse is not true.

Upgrade code that references table names

A major change in 4.0.0 is that now tables and class names can differ from model to model. In order to fix a table name, to prevent it being changed (for instance, when applying a namespace to a model) the table_name config can be applied to any DataObject class.

namespace SilverStripe\BannerManager;

use SilverStripe\ORM\DataObject;

class BannerImage extends DataObject
{
	private static $table_name = 'BannerImage';
}

In order to ensure you are using the correct table for any class a new [api:DataObjectSchema] service is available to manage these mappings (see versioned documentation).

public function countDuplicates($model, $fieldToCheck)
{
	$table = DataObject::getSchema()->tableForField($model, $field);
	$query = new SQLSelect();
	$query->setFrom("\"{$table}\"");
	$query->setWhere(["\"{$table}\".\"{$field}\"" => $model->$fieldToCheck]);
	return $query->count();
}

Upgrade BuildTask classes

Similarly to the $table_name configuration property for DataObjects, you should define a private static $segment for BuildTask instances to ensure that you can still run your task via sake dev/tasks/MyTask. Without defining it, the default will be a fully-qualified class name like sake dev/tasks/Me-MyModule-Tasks-MyTask. This can also be configured in YAML.

use SilverStripe\Dev\BuildTask;

class MyTask extends BuildTask
{
    private static $segment = 'MyTask';
}

Upgrade implementations of augmentSQL

Since this method now takes a SQLSelect as a first parameter, existing code referencing the deprecated SQLQuery type will raise a PHP error.

Before:

function augmentSQL(SQLQuery &$query, DataQuery &$dataQuery = null) {
	$locale = Translatable::get_current_locale();
	if(!preg_match('/("|\'|`)Locale("|\'|`)/', implode(' ', $query->getWhere())))  {
		$qry = sprintf('"Locale" = \'%s\'', Convert::raw2sql($locale));
		$query->addWhere($qry);
	}
}

After:

public function augmentSQL(SQLSelect $query, DataQuery $dataQuery = null)
{
	$locale = Translatable::get_current_locale();
	if (!preg_match('/("|\'|`)Locale("|\'|`)/', implode(' ', $query->getWhereParameterised($parameters))))  {
		$query->addWhere(array(
			'"Locale"' => $locale
		));
	}
}

Upgrade code that modifies the behaviour of ErrorPage

ErrorPage has been updated to use a configurable asset backend, similar to the AssetStore described above. This replaces the ErrorPage.static_filepath config that was used to write local files.

As a result, error pages may be cached either to a local filesystem, or an external Flysystem store (which is configured via setting a new Flysystem backend with YAML).

ErrorPage::get_filepath_for_errorcode() has been removed, because the local path for a specific code is no longer assumed. Instead you should use ErrorPage::get_content_for_errorcode which retrieves the appropriate content for that error using one of the methods above.

In order to retrieve the actual filename (which is used to identify an error page regardless of base path), you can use ErrorPage::get_error_filename() instead. Unlike the old get_filepath_for_errorcode method, there is no $locale parameter.

In case that user code must customise this filename, such as for extensions which provide a locale value for any error page, the extension point updateErrorFilename can be used. This extension point should also be used to replace any alternateFilepathForErrorcode used.

class MyErrorPageExtension extends SiteTreeExtension
{
	public function updateErrorFilename(&$name, &$statuscode)
    {
		if ($this->owner->exists()) {
			$locale = $this->Locale;
		} else {
			$locale = Translatable::get_current_locale();
		}
		$name = "error-{$statusCode}-{$locale}.html";
	}
}

ErrorPage:
  extensions:
    - MyErrorPageExtension

Upgrading asset web.config, .htaccess, or other server configuration

Server configuration files for /assets are no longer static, and are regenerated via a set of standard SilverStripe templates on flush. These templates include:

Assets_HTAccess.ss: Template for public permissions on the Apache server.
Assets_WebConfig.ss: Template for public permissions on the IIS server.
Protected_HTAccess.ss: Template for the protected store on the Apache server (should deny all requests).
Protected_WebConfig.ss: Template for the protected store on the IIS server (should deny all requests).

You will need to make sure that these files are writable via the web server, and that any necessary configuration customisation is done via overriding these templates.

If upgrading from an existing installation, make sure to invoke ?flush=all at least once.

See our "File Security" guide for more information.

`ListboxField` is now multiple-only

Previously, this field would operate as either a single select (default) or multi-select by setting setMultiple to either true or false.

Now this field should only be used for multi-selection. Single-selection should be done using a regular DropdownField.

`GroupedDropdownField::setDisabled` now only accepts a list of values.

Where previously you could specify a list of grouped values in the same way as setSource, this method now only accepts either a non-associative array of values (not titles) or an SS_List of items to disable.

Upgrading TinyMCE to 4.0

Please see the tinymce upgrading guide to assist with upgrades to customisations to tinymce 3.

In Framework 4.0 the user interface for TinyMCE has been trimmed down considerably, with certain toolbar buttons removed from the default cms configuration. These include:

Strikethrough
Styles dropdown
Block quotes
Horizontal Rule
Undo / Redo
Cut / Paste as word
Select all
Fullscreen

However, these function may be enabled on a case by case basis through modifification of the default tinymce config, or by creating custom configurations.

The optional ss_macron plugin for inserting Māori diacritical marks has been removed from core. You can configure the built-in charmap plugin instead:

$editor = HtmlEditorConfig::get('cms');
$editor->enablePlugins('charmap');
$editor->addButtonsToLine(1, 'charmap');
$editor->setOption('charmap_append', [
    ['256','A - macron'],
    ['274','E - macron'],
    ['298','I - macron'],
    ['332','O - macron'],
    ['362','U - macron'],
    ['257','a - macron'],
    ['275','e - macron'],
    ['299','i - macron'],
    ['333','o - macron'],
    ['363','u - macron']
]);

For more information on available options and plugins please refer to the TinyMCE documentation

Upgrading DataObjects with the `Versioned` extension

In most cases, versioned models with the default versioning parameters will not need to be changed. However, there are now additional restrictions on the use of custom stage names.

Rather than declaring the list of stages a model has, the constructor for Versioned will take a single mode parameter, which declares whether or not the model is versioned and has a draft and live stage, or alternatively if it only has versioning without staging.

/**
 * This model has staging and versioning. Stages will be "Stage" and "Live"
 */
class MyStagedModel extends DataObject
{
	private staic $extensions = array(
		"SilverStripe\\ORM\\Versioning\\Versioned('StagedVersioned')"
	);
}

/**
 * This model has versioning only, and will not has a draft or live stage, nor be affected by the current stage.
 */
class MyVersionedModel extends DataObject
{
	private static $extensions = array(
		"SilverStripe\\ORM\\Versioning\\Versioned('Versioned')"
	);
}

Additionally, the following api methods have been added:

Versioned::publishRecursive Publishes this object, and all owned objects
Versioned::publishSingle Publishes this object, but not owned objects
Versioned::copyVersionToStage Replaces the old publish method.

These methods are deprecated:

Versioned::publish Replaced by Versioned::copyVersionToStage
Versioned::doPublish Replaced by Versioned::publishRecursive

Implementation of ownership API

In order to support the recursive publishing of dataobjects, a new API has been developed to allow developers to declare dependencies between objects. See the versioned documentation for more information.

By default all versioned dataobjects will automatically publish objects that they own.

ChangeSet batch publishing

ChangeSet objects have been added, which allow groups of objects to be published in a single atomic transaction. This API will utilise the ownership API to ensure that changes to any object include all necessary changes to owners or owned entities within the same changeset.

New `[image]` shortcode in `HTMLText` fields

The new Ownership API relies on relationships between objects. Many of these relationships are already made explicit through has_one, has_many and many_many. Images inserted into HTMLText fields (through a WYSIWYG editor) need to be tracked as well. Instead of <img> tags, the field will insert [image] shortcodes which point to the database identifier of the Image record rather than its path on the filesystem. The shortcode will be automatically replaced when the field is rendered. Newly inserted images will automatically receive the shortcode and ownership tracking, and existing <img> will continue to work.

Upgrading references to DBField and subclasses

A major change in 4.0 is the introduction of namespaced DBField subclasses. Now as a standard, all DBField subclasses have a DB prefix, are namespaced, and have an associative alias which omits the DB prefix.

This means that for the most part, code that worked in 3.0 won't need to be changed, although if you have any hard class literals which reference the old classes, they will need to be updated to point to the new namespaced classes.

An exception to this is any classes which once had the SS_ prefix, which will now be instead prefixed with DB, and have an un-aliased prefix. For example SS_Datetime is now DBDateTime, and has the alias DateTime which may be used in config.

Before:

class MyObject extends DataObject {
    private static $db = array(
        'Number' => 'Int',
        'Time' => 'SS_Datetime'
    );

    /**
     * @param Int $val
     * @return Varchar
     */
    public function TextNumber() {
        return new Varchar('TextNumber', 'Number is ' . $this->Number);
    }
}

After:

use SilverStripe\ORM\DataObject;
use SilverStripe\ORM\FieldType\DBVarchar;

class MyObject extends DataObject
{
    private static $db = array(
        'Number' => 'Int',
        'Time' => 'Datetime'
    );

    /**
     * @param Int $val
     * @return Varchar
     */
    public function TextNumber()
    {
        return new DBVarchar('TextNumber', 'Number is ' . $this->Number);
    }
}

Note that string references to SS_Datetime passed to injector, or used in config values, will still work, and will refer to the updated class names.

Upgrading from deprecated RestfulService

Install Guzzle to get an API consuming library. composer require guzzlehttp/guzzle or add guzzlehttp/guzzle: "^6.0" to your composer.json.

For information on how to use Guzzle, please see the extensive Guzzle documentation

In case you want to keep using RestfulService, you can use Firesphere/silverstripe-restfulservice, but it is unmaintained and deprecated.

Upgrading from deprecated Oembed

Instead of Oembed, the framework now relies on oscarotero/Embed to handle getting the shortcode-data for embedding. If you have custom embedding-code relying on Oembed, please refer to the documentation provided by oscarotero.

Admin URL can now be configured via custom Director routing rule

The default admin/ URL to access the CMS interface can now be changed via a custom Director routing rule for AdminRootController. If your website or module has hard coded admin URLs in PHP, templates or JavaScript, make sure to update those with the appropriate function or config call. See CMS architecture for language specific functions.

Upgrading custom Authenticators

The methods register and unregister on Authenticator are deprecated in favor of the Config system. This means that any custom Authenticator needs to be registered through the yml config:

SilverStripe\Security\Authenticator;
  authenticators:
    - MyVendor\MyModule\MyAuthenticator

If there is no authenticator registered, Authenticator will try to fall back on the default_authenticator, which can be changed using the following config, replacing the MemberAuthenticator with your authenticator:

SilverStripe\Security\Authenticator:
  default_authenticator: SilverStripe\Security\MemberAuthenticator

As soon as a custom authenticator is registered, the default authenticator will not be available anymore, unless enabled specifically in the config.

By default, the SilverStripe\Security\MemberAuthenticator is seen as the default authenticator until it's explicitly set in the config.

Upgrading Config API usages

Performance optimisations have been made to Config which, under certain circumstances, require developer care when modifying or caching config values. The top level config object is now immutable on application bootstrap, and requires a developer to invoke Config::modify() to make mutable prior to modification. This will immediately have a slight performance hit, so should be done sparingly, and avoided at all if possible in performance intensive applications.

In addition, the Config::inst()->update() method is deprecated, and replaced with Config::modify()->set() and Config::modify()->merge() to respectively replace and merge config.

When config is merged (either via modification or merged between yml blocks) falsey-values (including nulls) now replace any prior values (even arrays).

One removed feature is the Config::FIRST_SET option. Either use uninherited config directly on the class directly, or use the inherited config lookup. As falsey values now overwrite all parent class values, it is now generally safer to use the default inherited config, where in the past you would need to use FIRST_SET.

Upgrading Cache API

We have replaced the unsupported Zend_Cache library with symfony/cache. This also allowed us to remove SilverStripe's Cache API and use dependency injection with a standard PSR-16 cache interface instead.

Caches should be retrieved through Injector instead of Cache::factory(), and have a slightly different API (e.g. set() instead of save()).

Before:

:::php
$cache = Cache::factory('myCache');
 
// create a new item by trying to get it from the cache
$myValue = $cache->load('myCacheKey');

// set a value and save it via the adapter
$cache->save(1234, 'myCacheKey');

// retrieve the cache item
if (!$cache->load('myCacheKey')) {
    // ... item does not exists in the cache
}

// Remove a cache key
$cache->remove('myCacheKey');

After:

:::php
use Psr\SimpleCache\CacheInterface;
$cache = Injector::inst()->get(CacheInterface::class . '.myCache');

// create a new item by trying to get it from the cache
$myValue = $cache->get('myCacheKey');

// set a value and save it via the adapter
$cache->set('myCacheKey', 1234);

// retrieve the cache item
if (!$cache->has('myCacheKey')) {
    // ... item does not exists in the cache
}

$cache->delete('myCacheKey');

With the necessary minimal config in _config/mycache.yml

:::yml
---
Name: mycache
---
SilverStripe\Core\Injector\Injector:
  Psr\SimpleCache\CacheInterface.myCache:
    factory: SilverStripe\Core\Cache\CacheFactory
    constructor:
      namespace: 'mycache'

Configuration Changes

Caches are now configured through dependency injection services instead of PHP. See our "Caching" docs for more details.

Before (mysite/_config.php):

:::php
Cache::add_backend(
    'primary_memcached', 
    'Memcached',
    array(
        'servers' => array(
            'host' => 'localhost', 
            'port' => 11211, 
        )
    )
);
Cache::pick_backend('primary_memcached', 'any', 10);

After (mysite/_config/config.yml):

:::yml
---
After:
  - '#corecache'
---
SilverStripe\Core\Injector\Injector:
  MemcachedClient:
    class: 'Memcached'
    calls:
      - [ addServer, [ 'localhost', 11211 ] ]
  SilverStripe\Core\Cache\CacheFactory:
    class: 'SilverStripe\Core\Cache\MemcachedCacheFactory'
    constructor:
      client: '%$MemcachedClient

API Changes

General and Core API

General and Core API Additions / Changes

A very small number of methods were chosen for deprecation, and will be removed in 5.0 rather than 4.0

ClassInfo::baseDataClass - Use DataObject::getSchema()->baseDataClass() instead.
ClassInfo::table_for_object_field - Use DataObject::getSchema()->tableForField() instead
Config::inst()->update() is deprecated. Use Config::modify()->set() or Config::modify()->merge() instead.

ORM API

ORM API Additions / Changes

Deprecate SQLQuery in favour SQLSelect
DataObject.many_many 'through' relationships now support join dataobjects in place of automatically generated join tables. See the [/developer_guides/relations](datamodel relationship docs) for more info.
DataList::filter by null now internally generates "IS NULL" or "IS NOT NULL" conditions appropriately on queries.
DataList::createDataObject is now public.
DataObject constructor now has an additional parameter, which must be included in subclasses.
DataObject::db now returns composite fields.
DataObject::ClassName field has been refactored into a DBClassName type field.
DataObject::can has new method signature with $context parameter.
DataObject::duplicate Now requires explicit flag to duplicate belongs_many_many (off by default), but now works with unsaved relations. By default only many_many are duplicated.
DBHTMLText no longer enables shortcodes by default. Two injector aliases have been created for this class which can be used to select the correct behaviour:
- HTMLText: DBHTMLText with shortcodes enabled
- HTMLFragment: DBHTMLText without shortcodes enabled (as default)
CMSPreviewable has been moved from the SilverStripe\Admin namespace to SilverStripe\ORM
Changes to DBString formatting:
- NoHTML is renamed to Plain
- LimitWordCountXML is removed. Use LimitWordCount instead.
- BigSummary is removed. Use Summary instead.
- Most limit methods on DBHTMLText now plain text rather than attempt to manipulate the underlying HTML.
FormField::Title and FormField::RightTitle are now cast as plain text by default (but can be overridden).
FormField#createTag() has been renamed to FormField::create_tag()
Hierarchy class has had much of it's functionality refactored out into MarkedSet:
- isMarked
- isTreeOpened
- isExpanded
- markByID
- markPartialTree
- markExpanded
- markUnexpanded
- markToExpose
- markClosed
- markOpened
- markedNodeIDs
- getChildrenAsUL replaced with renderChildren, which now takes a template name.
- markingFilterMatches (and made protected)
- markChildren (and made protected)
Removed DataList::applyFilterContext private method
Search filter classes (e.g. ExactMatchFilter) are now registered with Injector via a new DataListFilter. prefix convention. see search filter documentation for more information.
Permission::flush_permission_cache() renamed to reset() and added to Resettable interface.
Versioned API has some breaking changes:
- Versioned constructor now only allows a single string to declare whether staging is enabled or not. The number of names of stages are no longer able to be specified. See below for upgrading notes for models with custom stages.
- reading_stage is now set_stage and throws an error if setting an invalid stage.
- current_stage is now get_stage
- getVersionedStages is gone.
- get_live_stage is removed. Use the Versioned::LIVE constant instead.
- getDefaultStage is removed. Use the Versioned::DRAFT constant instead.
- $versionableExtensions is now private static instead of protected static
- hasStages is addded to check if an object has a given stage.
- stageTable is added to get the table for a given class and stage.
- Any extension declared via versionableExtensions config on Versioned dataobject must now VersionableExtension interface at a minimum. Translatable has been removed from default versionableExtensions
- The default CMS delete behaviour for versioned dataobjects is now to delete from both draft and live stages, and to save to the archive. There is no longer a separate "Archive" action.
- Any writes to versioned dataobjects (in either Draft or Live) will always write to the draft (main) table as a source of truth. This means that records created in Live mode will always be available to the CMS and in draft mode.
- _versions suffixed tables are now renamed to _Versions. This fix will be automatically applied during dev/build.
A lot of standard versioned API has been refactored from SiteTree into Versioned extension.
- All versioned DataObjects have canPublish(), canArchive(), canUnpublish() permission checks
- All versioned Dataobjects have doPublish(), doArchive(), doPublish(), and doUnpublish() actions. However, do*() methods will no longer automatically check can*() permissions, and must be done by usercode before invocation.
- SiteTree::getIsAddedToStage() moved to Versioned and renamed to isOnDraftOnly()
- SiteTre::getIsModifiedOnStage() moved to Versioned and renamed to isModifiedOnDraft()
- SiteTree::isPublished() moved to Versioned.
- SiteTree::getExistsOnLive() removed in favour of isPublished()
- isOnDraft() added to Versioned.
- isArchived() added to Versioned.
- isOnLiveOnly() added to Versioned.
ChangeSet and ChangeSetItem have been added for batch publishing of versioned dataobjects.
DataObject.table_name config can now be used to customise the database table for any record.
DataObjectSchema class added to assist with mapping between classes and tables.
DBMoney values are now treated as empty only if Amount field is null. If an Amount value is provided without a Currency specified, it will be formatted as per the current locale.
Removed DatabaseAdmin#clearAllData(). Use DB::get_conn()->clearAllData() instead
SapphireTest temp DB methods have been removed and put into a new TempDatabase class. This allows applications to create temp databases when not running tests. This class now takes a connection name as a constructor class, and no longer has static methods. The following methods have been moved to this new class and renamed as non-static:
- using_temp_db -> isUsed()
- kill_temp_db -> kill()
- empty_temp_db _> clearAllData()
- create_temp_db -> build()
- delete_all_temp_dbs -> deleteAll()
- resetDBSchema -> resetSchema()

The below methods have been added or had their functionality updated to DBDate, DBTime and DBDatetime

getTimestamp() added to get the respective date / time as unix timestamp (seconds since 1970-01-01)
Format() method now use CLDR format strings, rather than PHP format string. E.g. d/m/Y H:i:s (php format) should be replaced with to dd/MM/y HH:mm:ss (CLDR format).
getISOFormat() added which returns the standard date/time ISO 8601 pattern in CLDR format.
setValue method is now a lot more restrictive, and expects dates and times to be passed in ISO 8601 format (y-MM-dd) or (HH:mm:ss). Certain date formats will attempt to parse with the below restrictions:
- /, . or - are supported date separators, but will be replaced with - internally.
- US date formats (m-d-y / y-d-m) will not be supported and may be parsed incorrectly. (Note: Date form fields will still support localised date formats).
- dd-MM-y will be converted to y-MM-dd internally.
- 2-digit values for year will now raise errors.
FormatFromSettings will default to Nice() format if no member is logged in.
Nice, Long and Full methods will now follow standard formatting rules for the current locale, rather than pre-defined formats.
Short added to format concise date/time values, as a shorter version than Nice
getFormatter method added, which returns a locale-specific date/time formatter.

Filesystem API

Filesystem API Additions / Changes

Image manipulations have been moved into a new [api:ImageManipulation] trait.
CMSFileAddController removed.
UploadField::setAllowedFileCategories('image') now excludes non-resizeable images. 'unresizeable_image' is can be used to validate these types.
Image_Backend API now loads and saves from AssetContainer instances rather than local files.
The following File categories have been renamed: 'zip' to 'archive', 'doc' to 'document', and 'mov' to 'video'
File::updateLinks no longer takes urls as parameters. All file links are now identified either by the DataObject::ID in a data-fileid property, or via shortcodes. This is necessary because file urls are no longer able to identify assets.
Extension point HtmlEditorField::processImage has been removed, and moved to Image::regenerateImageHTML
Upload::load now stores assets directly without saving into a File dataobject.
Protected file storage is now a core Framework API. See [/developer_guides/files/file_security] for more information.
File is now versioned, and should be published before they can be used on the frontend. See section on Migrating File DataObject from 3.x to 4.0 below for upgrade notes.
New filesystem abstraction including new DBFile database field to hold file references.
ShortcodeHandler interface to help generate standard handlers for HTML shortcodes in the editor.
AssetNameGenerator interface, including a DefaultAssetNameGenerator implementation, which is used to generate renaming suggestions based on an original given filename in order to resolve file duplication issues.
GeneratedAssetHandler API now used to store and manage generated files (such as those used for error page cache or combined files).
Requirements_Minifier API can be used to declare any new mechanism for minifying combined required files. By default this api is provided by the JSMinifier class, but user code can substitute their own.
AssetField formfield to provide an UploadField style uploader for the new DBFile database field.
AssetControlExtension is applied by default to all DataObjects, in order to support the management of linked assets and file protection.
ProtectedFileController class is used to serve up protected assets.

Filesystem removed API

The following image manipulations previously deprecated has been removed:

Image::SetRatioSize superceded by Fit
Image::SetWidth superceded by ScaleWidth
Image::SetHeight superceded by ScaleHeight
Image::SetSize superceded by Pad
Image::PaddedImage superceded by Pad
Image::CroppedImage superceded by Fill
Image::AssetLibraryPreview superceded by PreviewThumbnail
Image::AssetLibraryThumbnail superceded by CMSThumbnail

The following File methods have been removed. Since there is no longer any assumed local path for any file, methods which dealt with such paths may no longer be relied on.

File::deletedatabaseOnly
File::link_shortcode_handler renamed to handle_shortcode
File::setParentID
File::getFullPath
File::getRelativePath
File::Content database field is removed

Image manipulations have been moved out of Image.php and now available to any File or DBFile which has the appropriate mime types. The following file manipulations classes and methods have been removed:

Image_Cached class
Image::regenerateFormattedImages method
Image::getGeneratedImages method
Image::deleteFormattedImages method
AssetAdmin::deleteunusedthumbnails method
AssetAdmin::getUnusedThumbnails method

Many Folder api have also been removed:

Folder::addUploadToFolder method

The following filesystem synchronisation methods and tasks are also removed

RegenerateCachedImagesTask class
CleanImageManipulationCache class
Filesystem::sync method
AssetAdmin::doSync method

Template and Form API

Template and Form API Additions / Changes

Upgrade of TinyMCE to version 4.
Templates now use a standard template lookup system via SSViewer::get_templates_by_class which builds a candidate list for a given class. Actual resolution of existing templates for any list of candidates is actually performed by SSViewer::chooseTemplate
HtmlEditorConfig is now an abstract class, with a default implementation TinyMCEConfig for the built in TinyMCE editor.
HtmlEditorField::setEditorConfig may now take an instance of a HtmlEditorConfig class, as well as a standard config identifier name.
HeaderField requires a $name constructor argument (new HeaderField('MyName', 'My Title')
default_cast is now enforced on all template variables. See upgrading notes below.
FormField templates no longer look in the 'forms' folder for templates. As all form fields are now namespaced, the path for these templates will now match the namespace of the given class instead.
$module parameter in themedCSS and themedJavascript removed.
Theme selector has been removed from SiteConfig. Please use SSViewer.themes config instead.
FormAction::setValidationExempt can be used to turn on or off form validation for individual actions
GridField edit form now has improved support for versioned DataObjects, with basic publishing actions available when editing records.
PopoverField added to provide popup-menu behaviour in react forms (currently not available for non-react forms).
Introduction of experimental FormFactory API as a substitute for DataObject classes being responsible for building their own form fields. This builds a form based on a given controller and model, and can be customised on a case by case basis. This has been introduced initially for the asset-admin module.
Introduced AssetAdmin\Forms\UploadField as a react-friendly version of UploadField. This may also be used in normal entwine forms for managing files in a similar way to UploadField. However, this does not support inline editing of files.
Added method FormField::setSubmittedValue($value, $data) to process input submitted from form submission, in contrast to FormField::setValue($value, $data) which is intended to load its value from the ORM. The second argument to setValue() has been added.
HTMLValue service name is now fully qualified SilverStripe\View\Parsers\HTMLValue.
FormField::create_tag() has been moved to HTML class and renamed to createTag. Invoke with HTML::createTag().

The following methods and properties on Requirements_Backend have been renamed:

Requirements_Backund::$combine_files made protected and renamed $combinedFiles
Requirements_Backend::$combine_js_with_min made protected and renamed $minifyCombinedFiles
Requirements_Backend::$write_header_comments made protected and renamed $writeHeaderComment
Requirements_Backend::$write_js_to_body made protected and renamed to $writeJavascriptToBody
Requirements_Backend::$force_js_to_bottom renamed to $forceJSToBottom
get_combined_files_enabled renamed to getCombinedFilesEnabled
set_combined_files_enabled renamed to setCombinedFilesEnabled
get_suffix_requirements renamed to getSuffixRequirements
set_suffix_requirements renamed to setSuffixRequirements
get_custom_scripts renamed to getCustomScripts
unblock_all renamed to unblockAll
include_in_response renamed to includeInResponse
combine_files renamed to combineFiles
get_combine_files renamed to getCombinedFiles
clear_combined_files renamed to clearCombinedFiles
process_combined_files renamed to processCombinedFiles
set_write_js_to_body renamed to setWriteJavascriptToBody
set_force_js_to_bottom renamed to setForceJSToBottom

New methods on Requirements are added to access these:

get_minify_combined_js_files
set_minify_combined_js_files
get_force_js_to_bottom
get_write_js_to_body

Some methods on Requirements have had their method signatures changed:

includeInHTML has had the first parameter $template removed as it was previously deprecated.

A new config Requirements_Backend.combine_in_dev has been added in order to allow combined files to be forced on during development. If this is off, combined files is only enabled in live environments.

Form validation has been refactored significantly. A new FormMessage trait has been created to handle field-level and form-level messages. This has the following properties:

setMessage to assign a message, type, and cast
getMessage retrieves the message string
getMessageType retrieves the message type (E.g. error, good, info)
getMessageCast retrieves the cast type
getMessageCastingHelper retrieves the DBField cast to use for the appropriate message cast
getSchemaMessage encodes this message for form schema use in ReactJS.

Form behaviour methods have been changed:

__construct() now allows a RequestHandler to be passed as a first argument, rather than a Controller. in addition this argument is now optional. This allows forms to be constructed as a model only.
validate is replaced with validationResult instead, which returns a ValidationResult instance. This is no longer automatically persisted in the state by default, unless a redirection occurs. You can also save any response in the state by manually invoking saveFormState inside a custom validation response handler.
setupFormErrors renamed to restoreFormState
resetValidation renamed to clearFormState
loadMessagesFrom method created to load a ValidationResult into a form.
setMessage. third parameter is now $cast type
messageForForm removed. Use setMessage or sessionMessage instead.
getSessionValidationResult / setSessionValidationResult used to get / set session errors
getSessionData / setSessionData used to get / set field values cached in the session
getAjaxErrorResponse and getRedirectReferer created to simplify getValidationErrorResponse
addErrorMessage removed. Users can either use sessionMessage or sessionError to add a form level message, throw a ValidationException during submission, or add a custom validator.
Form is no longer a RequestHandler, but implements the HasRequestHandler interface and returns a FormRequestHandler instance from getRequestHandler(). the Form constructor no longer has any mandatory parameters, and the first parameter allows a non-Controller RequestHandler to be passed. Certain methods have been moved from Form to FormRequestHandler:
- buttonClicked
- checkAccessAction
- handleField
- httpSubmission
- Link

Validator methods have changed:

validate method now returns a ValidationResult instance.
requireField method removed. Use RequiredFields subclass instead.

ValidationResult now has these methods:

serialize / unserialize for saving within session state
messageList renamed to getMessages
error method replaced with addMessage / addError / addFieldMessage / addFieldError
valid renamed to isValid

ValidationException has these changes:

$message second constructor parameter is removed. Constructor only accepts $result, which may be a string, and optional $code

New DatetimeField methods replace getConfig() / setConfig():

getTimezone() / setTimezone()
getDateTimeOrder() / setDateTimeOrder()
getLocale() / setLocale()
datavaluefield config is removed as internal data value is now fixed to ISO 8601 format

The DatetimeField has changed behaviour:

It uses a combined input instead of a composite from DateField and TimeField Consequently, getDateField() and getTimeField() have been removed.
It returns ISO 8601 normalised dates by default in Value(), which include a "T" separator between date and time. This is required to allow HTML5 input. Either use setHTML5(false) to set your custom format, or use dataValue() to retrieve a whitespace separated representation.
It no longer accepts setValue() as an array with 'date' and 'time' keys
Added getHTML5() / setHTML5()

New DateField methods replace getConfig() / setConfig():

getDateFormat() / setDateFormat()
getMinDate() / setMinDate()
getMaxDate() / setMaxDate()
getLocale() / setLocale()

The DateField has changed behavior:

DateField no longer provides a jQuery UI date picker (showcalendar option), and uses HTML5 date pickers by default instead.
DateField provides an optional polyfill for browsers without HTML5 date picker support
The dmyfields option has been replced with native HTML5 behaviour (as one single <input type=date>).
getClientLocale / setClientLocale have been removed (handled by DateField->locale and browser settings)

New TimeField methods replace getConfig() / setConfig()

getTimeFormat() / setTimeFormat()
getLocale() / setLocale()
getClientConfig() has been removed (in favour of setHTML5())
