Deprecation: #107287 - FileCollectionRegistry->addTypeToTCA() method 

See forge#107287

Description 

The method \TYPO3\CMS\Core\Resource\Collection\FileCollectionRegistry->addTypeToTCA() has been deprecated in TYPO3 v14.0 and will be removed in TYPO3 v15.0.

This method was originally intended to register additional file collection types by directly manipulating the global $GLOBALS['TCA'] array for the sys_file_collection table. With modern TCA configuration patterns, this approach is no longer recommended.

Impact 

Calling this method will trigger a deprecation-level log entry and will stop working in TYPO3 v15.0.

Affected installations 

Instances using the FileCollectionRegistry->addTypeToTCA() method directly are affected.

The extension scanner will report usages as weak match.

Migration 

Instead of using this method, configure file collection types directly in your TCA configuration files. Move the TCA configuration from the method call to your extension's Configuration/TCA/Overrides/sys_file_collection.php file.

Before (deprecated) 
use TYPO3\CMS\Core\Resource\Collection\FileCollectionRegistry;
use TYPO3\CMS\Core\Utility\GeneralUtility;

$fileCollectionRegistry = GeneralUtility::makeInstance(
    FileCollectionRegistry::class
);
$fileCollectionRegistry->addTypeToTCA(
    'mytype',
    'My Collection Type',
    'description,my_field',
    ['my_field' => ['config' => ['type' => 'input']]]
);
Copied!
After (recommended) – EXT:my_extension/Configuration/TCA/Overrides/sys_file_collection.php 
use TYPO3\CMS\Core\Utility\ExtensionManagementUtility;

$GLOBALS['TCA']['sys_file_collection']['types']['mytype'] = [
    'showitem' => '
        sys_language_uid, l10n_parent, l10n_diffsource,
        title, --palette--;;1, type, description, my_field
    ',
];

$GLOBALS['TCA']['sys_file_collection']['columns']['type']['config']['items'][] =
    [
        'label' => 'My Collection Type',
        'value' => 'mytype',
    ];

// Add additional columns if needed
ExtensionManagementUtility::addTCAcolumns(
    'sys_file_collection',
    [
        'my_field' => [
            'config' => [
                'type' => 'input',
            ],
        ],
    ]
);
