BeforeModuleCreationEvent

The PSR-14 event \TYPO3\CMS\Backend\Module\BeforeModuleCreationEvent allows extension authors to manipulate the module configuration, before it is used to create and register the module.

Example

EXT:my_extension/Classes/Backend/EventListener/MyEventListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Backend\EventListener;

use TYPO3\CMS\Backend\Module\BeforeModuleCreationEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-extension/backend/modify-module-icon',
)]
final readonly class MyEventListener
{
    public function __invoke(BeforeModuleCreationEvent $event): void
    {
        // Change module icon of page module
        if ($event->getIdentifier() === 'web_layout') {
            $event->setConfigurationValue('iconIdentifier', 'my-custom-icon-identifier');
        }
    }
}

New in version 13.0

The PHP attribute \TYPO3\CMS\Core\Attribute\AsEventListener has been introduced to tag a PHP class as an event listener. Alternatively, or if you need to be compatible with older TYPO3 versions, you can also register an event listener via the Configuration/Services.yaml file. Switch to an older version of this page for an example or have a look at the section Implementing an event listener in your extension.
