TCA Overrides

Mask has a bunch of options integrated from TCA (Table Configuration Array), but it will probably never have the complete power to provide every option. There are simply too many possibilities, which need to be considered. Therefore it is advised, to manually override the generated Mask TCA, if more options are desired.

How to override Mask TCA


First make sure, you added Mask as a dependency in your sitepackage, like explained in the installation guide.

Fields in tt_content

It works exactly like overriding core TCA. You only need to know, what Mask generates. Normal fields defined in the root-level are belonging to the table tt_content and are always prefixed with tx_mask_. To override TCA from such a field, just extend the TCA in Configuration/TCA/Overrides/tt_content.php.


$GLOBALS['TCA']['tt_content']['columns']['tx_mask_your_field']['config']['some_option'] = 'some_value';

Fields in custom tables

As soon as you create a repeating field, Mask creates a new custom table. Therefore you need to change the key to the table’s name. Extend the TCA in Configuration/TCA/Overrides/tx_mask_custom_table.php


$GLOBALS['TCA']['tx_mask_custom_table']['columns']['tx_mask_your_field']['config']['some_option'] = 'some_value';

This is all you need to know. You have the full capabilities of the TCA and you are not limited by Mask’s features. Mask strives to add as many features of the TCA as possible, but you don’t have to wait for that.
