Feature: #108027 - Type-specific title in TCA types section

Description

It is now possible to define a type-specific title in the TCA types section. This value overrides the global table title defined in ctrl['title'] for the respective record type.

This allows different record types of the same table to display different titles in the TYPO3 backend user interface, making it clearer which kind of record is being created or displayed.

Note

In addition to title, the previewRenderer property can also be overridden per type. This was already possible through explicit evaluation and use of the Schema API, but is now consistently respected by FormEngine as well.

Implementation

This feature has been implemented in two areas to ensure consistent behavior:

Schema API The TcaSchemaFactory merges type-specific configuration into sub-schemas using array_replace_recursive(). This makes type-specific titles available through $schema->getTitle().
FormEngine The data provider TcaTypesCtrlOverrides merges the type-specific title and previewRenderer into processedTca['ctrl'] during form rendering. This ensures that both FormEngine and any legacy code accessing ctrl directly will see the correct type-specific values.

Example

EXT:my_extension/Configuration/TCA/tx_my_table.php

return [
    'ctrl' => [
        'title' => 'my_extension.db:tx_my_table',
        'type' => 'record_type',
        // ... other ctrl configuration
    ],
    'types' => [
        'article' => [
            'title' => 'my_extension.db:tx_my_table.type.article',
            'showitem' => 'title, content, author',
        ],
        'news' => [
            'title' => 'my_extension.db:tx_my_table.type.news',
            'showitem' => 'title, content, publish_date',
        ],
        'event' => [
            // No type-specific title - will use the global ctrl['title']
            'showitem' => 'title, content, event_date',
        ],
    ],
    // ... columns configuration
];

In this example:

The article type displays the title defined in the language file key tx_my_table.type.article.
The news type displays the title defined in tx_my_table.type.news.
The event type falls back to the global table title from ctrl['title'].

Impact

Tables with multiple record types can now define more specific and descriptive titles for each type in the backend user interface. This improves usability and clarity for editors by making it immediately obvious which type of record is being created or edited.

This feature is especially useful for:

Content element tables such as tt_content with different CType values
Tables with distinct record types serving different purposes
Plugin records with varying functionality per type
Any table where the record type changes the record's purpose or meaning
