Feature: #94406 - Override fileFolder TCA configuration with TSconfig

See Issue #94406

Description

The special fileFolder configuration options for TCA columns of type select can be used to fill a select field with files (images / icons) from a defined folder. This is really handy, e.g. for selecting predefined icons from a corporate icon set. However, in installations with multiple sites, such icon sets usually differ from site to site.

Therefore, the fileFolder configuration can now be overridden with page TSconfig, allowing administrators to easily handle those situations by e.g. using different folders or allowing different file extensions, per site.

To streamline both, the TCA configuration and the corresponding overrides, the fileFolder configuration options have been moved into a dedicated sub array fileFolderConfig, some options have been renamed:

  • fileFolder option folder
  • fileFolder_extList to allowedExtensions
  • fileFolder_recursions to depth

A TCA migration wizard is available, showing where adjustments have to take place.

Before:

'aField' => [
   'config' => [
      'type' => 'select',
      'renderType' => 'selectSingle',
      'fileFolder' => 'EXT:my_ext/Resources/Public/Icons',
      'fileFolder_extList' => 'svg',
      'fileFolder_recursions' => 1,
   ]
]

After:

'aField' => [
   'config' => [
      'type' => 'select',
      'renderType' => 'selectSingle',
      'fileFolderConfig' => [
         'folder' => 'EXT:styleguide/Resources/Public/Icons',
         'allowedExtensions' => 'svg',
         'depth' => 1,
      ]
   ]
]

Thus, the following TSconfig options can be used to overriding their TCA counterpart:

config.fileFolderConfig.folder
config.fileFolderConfig.allowedExtensions
config.fileFolderConfig.depth

As already known from TCEFORM, those options can be used on various levels

On table level:

TCEFORM.myTable.myField.config.fileFolderConfig.folder

On table and record type level:

TCEFORM.myTable.myFiled.types.myType.config.fileFolderConfig.folder

On flex form field level:

TCEFORM.myTable.pi_flexform.my_ext_pi1.sDEF.myField.config.fileFolderConfig.folder

Note

Except config.fileFolderConfig.folder, the new options can not only be used to override an existing property, but also to define one, which has not yet been configured in TCA.

Impact

It’s now possible to override the TCA fileFolder configuration options with page TSconfig, allowing administrators to manipulate the available items on a page basis.

The fileFolder TCA configuration is furthermore streamlined and now encapsulated in a dedicated sub array fileFolderConfig.
