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.

Note

The Configuration module is part of the lowlevel system extension. In Composer mode you can install it with:

composer req typo3/cms-lowlevel
The Configuration module

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.
