TYPO3 Extbase individual code on backend-deletion of an object

Question

I would like to execute some individual code when one of my Extbase domain objects is deleted from the list view in TYPO3 backend.

Thought that it could / would work

Answer 1

In addition to biesiors answer I want to point out, that there is also a signalSlot for this. So you can rather register on that signal than hooking into tcemain.

in your ext_localconf.php put:

$signalSlotDispatcher =
            \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\SignalSlot\\Dispatcher');
$signalSlotDispatcher->connect(
    'TYPO3\CMS\Extbase\Persistence\Generic\Backend',
    'afterRemoveObject',
    'Vendor\MxExtension\Slots\MyAfterRemoveObjectSlot',
    'myAfterRemoveObjectMethod'
);

So in your Slot you have this PHP file:

namespace Vendor\MxExtension\Slots;
class MyAfterRemoveObjectSlot {
    public function myAfterRemoveObjectMethod($object) {
         // do something
    }
}

Note thet $object will be the $object that was just removed from the DB.
