AfterTypoLinkDecodedEvent

New in version 13.0

This event has been introduced to avoid extending/XCLASSing the \TYPO3\CMS\Core\LinkHandling\TypoLinkCodecService. Extending/XCLASSing no longer works since TYPO3 v13, as the TypoLinkCodecService has been declared as final and readonly.

The PSR-14 event \TYPO3\CMS\Core\LinkHandling\Event\AfterTypoLinkDecodedEvent allows developers to fully manipulate the decoding of TypoLinks.

A common use case for extensions is to extend the TypoLink parts to allow editors adding additional information, for example, custom attributes can be inserted to the link markup.

Example

EXT:my_extension/Classes/LinkHandling/EventListener/MyEventListener.php 
<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\LinkHandling\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\LinkHandling\Event\AfterTypoLinkDecodedEvent;

#[AsEventListener(
    identifier: 'my-extension/after-typolink-decoded',
)]
final readonly class MyEventListener
{
    public function __invoke(AfterTypoLinkDecodedEvent $event): void
    {
        $typoLink = $event->getTypoLink();
        $typoLinkParts = $event->getTypoLinkParts();

        if (str_contains($typoLink, 'foo')) {
            $typoLinkParts['foo'] = 'bar';
            $event->setTypoLinkParts($typoLinkParts);
        }
    }
}
Copied!

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, you can also register an event listener via the Configuration/Services.yaml file. Have a look into the section Implementing an event listener in your extension.
