TYPO3 Custom Page Properties

Question

I'm trying to make the Publish Date mandatory for my "Article" page type.

I added this code

$fields_article = array(
    'starttime' => [
        'label' => 'Publish Date',
        'config' => [
            'type' => 'input',
            'eval' => 'datetime,required'
        ],
    ]
);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns('pages', $fields_article);
$showItem = "--div--;Page Settings";
$showItem .= ",--linebreak--,starttime";
$GLOBALS['TCA']['pages']['types'][$doktypeArticlePage] = array(
    'showitem' => $showItem
);

And this works, but it makes the Publish Date mandatory for all page types. Is it possible to only add the required tag to article page types?

Answer 1

There is no default way to set eval based on type, so I'm afraid there's no easy way to do this.

You could most likely do this with a custom eval. See the Vendor\\Extention\\* section in https://docs.typo3.org/typo3cms/TCAReference/latest/ColumnsConfig/Type/Input.html#eval for more information about that.

Alternatively you could create a new required field, which is only shown in your "Article" page type, and use one of the hook in TYPO3\\CMS\\Core\\DataHandling\\DataHandler to copy its value to the starttime field.
