New in version 12.3

The PSR-14 event \TYPO3\CMS\Redirects\Event\ModifyAutoCreateRedirectRecordBeforePersistingEvent allows extensions to modify the redirect record before it is persisted to the database. This can be used to change values according to circumstances, such as different sub-tree settings that are not covered by the Core site configuration. Another use case could be to write data to additional sys_redirect columns added by a custom extension for later use.




namespace MyVendor\MyExtension\Redirects\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Redirects\Event\ModifyAutoCreateRedirectRecordBeforePersistingEvent;
use TYPO3\CMS\Redirects\RedirectUpdate\PlainSlugReplacementRedirectSource;

    identifier: 'my-extension/modify-auto-create-redirect-record-before-persisting',
final readonly class MyEventListener
    public function __invoke(
        ModifyAutoCreateRedirectRecordBeforePersistingEvent $event,
    ): void {
        // Only work on plain slug replacement redirect sources.
        if (!($event->getSource() instanceof PlainSlugReplacementRedirectSource)) {

        // Get prepared redirect record and change some values
        $record = $event->getRedirectRecord();

        // Override the status code, eventually to another value than
        // configured in the site configuration
        $record['status_code'] = 307;

        // Set value to a field extended by a custom extension, to persist
        // additional data to the redirect record.
            = 'page_' . $event->getSlugRedirectChangeItem()->getPageId();

        // Update changed record in event to ensure changed values are saved.

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.


class ModifyAutoCreateRedirectRecordBeforePersistingEvent
Fully qualified name

This event is fired in the TYPO3CMSRedirectsServiceSlugService before a redirect record is persisted for changed page slug.

It can be used to modify the redirect record before persisting it. This gives extension developers the ability to apply defaults or add custom values to the record.
