Installation

Installation can be done either by composer or by manually downloading a release.

Via composer

composer require "silverstripe/userforms:*"

Manually

Download the module from the releases page.
Extract the file (if you are on windows try 7-zip for extracting tar.gz files
Make sure the folder after being extracted is named 'userforms'
Place this directory in your sites root directory. This is the one with framework and cms in it.

Configuration

After installation, make sure you rebuild your database through dev/build.

You should see a new PageType in the CMS 'User Defined Form'. This has a new 'Form' tab which has your form builder.

File Uploads and Security

The module optionally allows adding a "File Upload Field" to a form. The field enables users of this form to upload files to the website's assets so they can be viewed later by CMS authors. Small files are also attached to the (optional) email notifications to any configured recipients.

Allowed file extensions can be configured globally through File.allowed_extensions, and default to a safe set of files (e.g. disallowing *.php uploads). You can define further exclusions through the EditableFileField.allowed_extensions_blacklist configuration setting.

The allowed upload size is determined by PHP configuration for this website (the smaller value of upload_max_filesize or post_max_size).

The field is disabled by default since implementors need to determine how files are secured. Since uploaded files are kept in assets/ folder of the webroot, there is no built-in permission control around who can view them. It is unlikely that website users guess the URLs to uploaded files unless they are specifically exposed through custom code.

You should think carefully about the use case for file uploads. Unauthorised viewing of files might be desired, e.g. submissions for public competitions. In other cases, submissions could be expected to contain private data.

In order to enable this field it is advisable to install the secureassets module.

This can be done using the below composer command:

composer require silverstripe/secureassets ~1.0.4

This step will have the following effects:

The "File Upload Field" will be enabled through the CMS interface
By default any new file upload fields will be assigned to a default folder, SecureUploads, which can only be accessed by admins.
Any existing file upload fields, if they are not assigned to a folder, will now upload to this folder.
Any existing file upload fields which are assigned folders will have the security settings for those folders updated so that only admins can access them.

This functionality can be configured in the following ways:

Assigning another group to the SecureUploads folder will allow users from that group (rather than admins only) to access those files.
The folder name can be configured using the EditableFileField.secure_folder_name config option.
Security functionality can be disabled (although this is not advisable) by setting EditableFileField.disable_security to true.

Custom email templates

If you want to use custom email templates set the following config option.

UserDefinedForm:
  email_template_directory: your/template/path/

Any SilverStripe templates placed in your email_template_directory directory will be available for use with submission emails.
