TYPO3如何修改TCA？

Question

TYPO3 9, but is probably independent of TYPO3 version

I have installed news and eventnews . eventnews adds a field location_simple to the table tx_news_domain_model_news . In the backend this is of type input . I want it to be of type text . Therefore I added a file Configuration/TCA/Overrides/tx_news_domain_model_news.php to my sitepackage:

<?php
if( !defined('TYPO3_MODE') ) {
    die ('Access denied.');
}

// Modify location simple
$GLOBALS['TCA']['tx_news_domain_model_news']['columns']['location_simple']['config']['type'] = 'text';

But this has no effect.

My sitepackage is included at last position, so it should be able to overwrite the TCA of eventnews . What is correct the magic for this?

Answer 1

This worked for me: rename my site package extension so that it has an extension key alphabetically after 'e'.

It seems as if the files in /Configuration/TCA/Overrides are read alphabetically. In my case I wanted to override eventnews . So my site package extension key had to begin with a letter in [fz].
