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.

Verifying the $TCA

You may find it necessary – at some point – to verify the full structure of the $GLOBALS['TCA'] in your TYPO3 installation. The System > Configuration module makes it possible to have an overview of the complete $GLOBALS['TCA'], with all customizations taken into account.

Checking the existence of the new field via the Configuration module

If you cannot find your new field, it probably means that you have made some mistake.

This view is also useful when trying to find out where to insert a new field, to explore the combination of types and palettes that may be used for the table that we want to extend.
