Element Change Events

If you want to execute additional actions after a element is created, updated or deleted, you can use an EventListener to trigger your own actions.

The \MASK\Mask\Event\MaskAfterElementSavedEvent event is directly executed after a content element is added or updated. It has the modified TableDefinitionCollection and element key as parameters, as well as information if the content element was created or updated.

The \MASK\Mask\Event\MaskAfterElementDeletedEvent event is directly executed after a content element is deleted. It has the modified TableDefinitionCollection and element key of the former existing content element as parameters.

MaskAfterElementSavedEvent EventListener example

EXT:some_extension/Classes/EventListener/MaskAfterElementSavedEventListener.php

<?php

declare(strict_types=1);

namespace VENDOR\SomeExtension\EventListener;

use MASK\Mask\Event\MaskAfterElementSavedEvent;

class MaskAfterElementSavedEventListener
{
    public function __invoke(MaskAfterElementSavedEvent $event): void
    {
         $tableDefinition = $event->getTableDefinitionCollection();
         $elementKey = $event->getElementKey();
         if ($event->isNewElement() {
            // do something if the element is newly created
         } else {
            // do something if the element is updated
         }
    }
}

MaskAfterElementDeletedEvent EventListener example

        EXT:some_extension/Classes/EventListener/MaskAfterElementDeletedEventListener.php
    

<?php

declare(strict_types=1);

namespace VENDOR\SomeExtension\EventListener;

use MASK\Mask\Event\MaskAfterElementDeletedEvent;

class MaskAfterElementDeletedEventListener
{
    public function __invoke(MaskAfterElementDeletedEvent $event): void
    {
         $tableDefinition = $event->getTableDefinitionCollection();
         $elementKey = $event->getElementKey();
