Attention
TYPO3 v6 has reached its end-of-life April 18th, 2017 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 strongly recommended updating your project.
Extending the $TCA array¶
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.
