ModifyButtonBarEvent¶

New in version 12.0

This event serves as a direct replacement for the removed hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['Backend\Template\Components\ButtonBar']['getButtonsHook'].

The PSR-14 event \TYPO3\CMS\Backend\Template\Components\ModifyButtonBarEvent can be used to modify the button bar in the TYPO3 backend module docheader.

Example¶

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

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Backend\EventListener;

use TYPO3\CMS\Backend\Template\Components\ModifyButtonBarEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-extension/backend/modify-button-bar',
)]
final readonly class MyEventListener
{
    public function __invoke(ModifyButtonBarEvent $event): void
    {
        // Do your magic here
    }
}

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.
