Attention

TYPO3 v8 has reached its end-of-life March 31st, 2020 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.

There is no further ELTS support. It is recommended that you upgrade your project and use a supported version of TYPO3.

Being a PHP array, the Table Configuration Array can be easily extended. It can be accessed as the global variable $GLOBALS['TCA']. TYPO3 also provides APIs for making this simpler.
