TCA Änderungenin TYPO3 6.2
am Beispiel einer Erweiterung der News Extension
bisherige Situation• Erweiterungen in ext_tables.php
• Kein Code Cache
• ext_tables.php wird zur Laufzeit mehrfach eingelesen
• Unübersichtlich. Änderungen können sich leicht gegenseitig überschreiben.
Configuration/TCA/Overrides
• Eingeführt mit TYPO3 6.2
• Beliebiger Dateiname
• Beliebig viele Dateien möglich
• Best practice:<extkey>/Configuration/TCA/Overrides/<tablename>.php
Vorteile
• klar definierte Stelle, wo Änderungen passieren
• TCA Änderungen landen im Code Cache
• ext_tables.php wird entschlackt
• Performance Gewinn im Backend wenn alle Extensions das Feature nutzen
Beispiele• Systemextensions
• css_styled_content
• saltedpasswords
• felogin
• news_exampleextension
News erweitern
Neue News Typen und ein neues Feld
Struktur• Extbase Verzeichnisstruktur
• Resources/Private/extend-news.txt
• enthält Pfade zu den Dateien, die erweitert werden sollen
• Ohne Dateiendung .php
• Beispiel: Domain/Model/News
Configuration/TCA/Overrides/ tx_news_domain_model_news.php
