Andre Kiste cc712892a9 NEW Port betterbuttons to framework (#8569)
* MINOR: Add `Previous`, `Next` and `Create New` actions in edit form

If the form is opened via a grid field, the filters will be retained so the previous/next record opened will be correct

* MINOR: Add ability to customise the visibility of the `Previous`, `Next` and `Add` buttons at a `GridField` level

* Fix invalid action when pressing the `New` button in an edit form unless `betterbuttons` module was installed

* - Merge `showPrevious` and `showNext` to `showPagination` for grid fields
- Update documentation
- Improve performance for next/previous buttons by not fetching all list records
- Refactoring

* Refactor to fail gracefully on GridFieldPaginator

# How to customise the CMS Menu
## Adding an administration panel
Every time you add a new extension of the [LeftAndMain](api:SilverStripe\Admin\LeftAndMain) class to the CMS,
SilverStripe will automatically create a new [CMSMenuItem](api:SilverStripe\Admin\CMSMenuItem) for it
The most popular extension of LeftAndMain is a [ModelAdmin](api:SilverStripe\Admin\ModelAdmin) class, so
for a more detailed introduction to creating new `ModelAdmin` interfaces, read
the [ModelAdmin reference](../modeladmin).
In this document we'll take the `ProductAdmin` class used in the
[ModelAdmin reference](../modeladmin#setup) and so how we can change
the menu behaviour by using the `$menu_title` and `$menu_icon` statics to
provide a custom title and icon.
### Defining a Custom Icon
First we'll need a custom icon. For this purpose SilverStripe uses 16x16
black-and-transparent PNG graphics. In this case we'll place the icon in
`app/images`, but you are free to use any location.
```php
use SilverStripe\Admin\ModelAdmin;
class ProductAdmin extends ModelAdmin
{
// ...
private static $menu_icon = 'app/images/product-icon.png';
}
```
### Defining a Custom Title
The title of menu entries is configured through the `$menu_title` static.
If its not defined, the CMS falls back to using the class name of the
controller, removing the "Admin" bit at the end.
```php
use SilverStripe\Admin\ModelAdmin;
class ProductAdmin extends ModelAdmin
{
// ...
private static $menu_title = 'My Custom Admin';
}
```
In order to localize the menu title in different languages, use the
`<classname>.MENUTITLE` entity name, which is automatically created when running
the i18n text collection.
For more information on language and translations, please refer to the
[i18n](/developer_guides/i18n) docs.
## Adding an external link to the menu
On top of your administration windows, the menu can also have external links
(e.g. to external reference). In this example, we're going to add a link to
Google to the menu.
First, we need to define a [LeftAndMainExtension](api:SilverStripe\Admin\LeftAndMainExtension) which will contain our
button configuration.
```php
use SilverStripe\Admin\CMSMenu;
use SilverStripe\Admin\LeftAndMainExtension;
class CustomLeftAndMain extends LeftAndMainExtension
{
public function init()
{
// unique identifier for this item. Will have an ID of Menu-$ID
$id = 'LinkToGoogle';
// your 'nice' title
$title = 'Google';
// the link you want to item to go to
$link = 'http://google.com';
// priority controls the ordering of the link in the stack. The
// lower the number, the lower in the list
$priority = -2;
// Add your own attributes onto the link. In our case, we want to
// open the link in a new window (not the original)
$attributes = [
'target' => '_blank'
];
CMSMenu::add_link($id, $title, $link, $priority, $attributes);
}
}
```
To have the link appear, make sure you add the extension to the `LeftAndMain`
class. For more information about configuring extensions see the
[extensions reference](/developer_guides/extending/extensions).
```php
LeftAndMain::add_extension('CustomLeftAndMain')
```
## Customising the CMS help menu
The CMS help menu links in the south toolbar are configurable via your [configuration file](../../configuration).
You can edit, add or remove existing links as shown in the examples below:
```yml
# app/_config/config.yml
SilverStripe\Admin\LeftAndMain:
help_links:
# Edit an existing link
'CMS User help': 'https://example.com'
# Add a new link
'Additional link': 'https://example.org'
# Remove an existing link
'Feedback': ''
```
## Customising the CMS form actions
The `Previous`, `Next` and `Add` actions on the edit form are visible by default but can be hidden globally by adding the following `.yml` config:
```yml
SilverStripe\Forms\GridField\GridFieldDetailForm_ItemRequest:
formActions:
showPagination: false
showAdd: false
```
You can also override this for a specific `GridField` instance when using the `GridFieldConfig_RecordEditor` constructor:
```php
$grid = new GridField(
"pages",
"All Pages",
SiteTree::get(),
GridFieldConfig_RecordEditor::create(null, false, false));
```
