Deprecation: #69754 - Deprecate relative path to extension directory and using filename only in TCA ctrl iconfile

See Issue #69754

Description

  • Using relative paths to refer to the extension directory for iconfiles in TCA['ctrl']['iconfile'] has been marked as deprecated.
  • Using filenames only to refer to an iconfile in TCA[‘ctrl’] has been marked as deprecated.

Impact

  • TCA definitions in TCA['ctrl']['iconfile'] containing '../typo3conf/ext/' or calls to \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extRelPath() will trigger a deprecation log entry.
  • TCA definitions in TCA['ctrl']['iconfile'] containing a filename only will trigger a deprecation log entry.

Affected Installations

Any installation with extensions defining TCA['ctrl']['iconfile'] by using ../typo3conf/ext/ or only a filename.

Migration

Relative paths

Use EXT: instead of relative path '../typo3conf/ext/' or \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extRelPath() , e.g.

'ctrl' => array(
        'iconfile' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extRelPath('my_extension') . 'Resources/Public/Icons/image.png'
),

has to be migrated to

'ctrl' => array(
        'iconfile' => 'EXT:my_extension/Resources/Public/Icons/image.png'
),

Filename only

Use a full absolute path or an EXT: definition instead of a filename only:

'ctrl' => array(
        'iconfile' => '_icon_ftp.gif'
),

has to be migrated to

'ctrl' => array(
        'iconfile' => 'EXT:t3skin/icons/gfx/i/_icon_ftp.gif'
),

or

'ctrl' => array(
        // You can use absolute paths (to your web root folder) to the icons but
        // it is discouraged to do so as these icons belong to an extension they
        // should also be stored in this extension
        'iconfile' => '/fileadmin/icons/_icon_ftp.gif'
),
