Feature: #95105 - New PSR-14 DatabaseRecordList events

Description

A couple of new PSR-14 events for the \TYPO3\CMS\Recordlist\RecordList\DatabaseRecordList class have been added to TYPO3 Core. They are mainly a direct replacement for the hook methods, defined in the \TYPO3\CMS\Recordlist\RecordList\RecordListHookInterface, while their functionality is improved and extended.

The new events can be used to modify the behaviour of each table listing, which means they can be used to either add, change or even remove columns and actions.

Following events have been added:

\TYPO3\CMS\Recordlist\Event\ModifyRecordListTableActionsEvent
\TYPO3\CMS\Recordlist\Event\ModifyRecordListHeaderColumnsEvent
\TYPO3\CMS\Recordlist\Event\ModifyRecordListRecordActionsEvent

They all behave in the same way. There is always the subject, e.g. the record actions or the header columns, together with information like the current table, the current DatabaseRecordList instance and the current record or the record uids. The subject is therefore equipped with the usual CRUD methods like set, get or remove. This makes working with those values much more pleasant. See the below code examples on how those can be used. Some events also feature additional methods to influence e.g. the table header attributes or the label, which is being displayed in case no actions are available for the current user.

An example registration of the events in your extensions' Services.yaml:

MyVendor\MyPackage\RecordList\MyEventListener:
  tags:
    - name: event.listener
      identifier: 'my-package/recordlist/my-event-listener'
      method: 'modifyRecordActions'
    - name: event.listener
      identifier: 'my-package/recordlist/my-event-listener'
      method: 'modifyHeaderColumns'
    - name: event.listener
      identifier: 'my-package/recordlist/my-event-listener'
      method: 'modifyTableActions'

The corresponding event listener class:

use Psr\Log\LoggerInterface;
use TYPO3\CMS\Recordlist\Event\ModifyRecordListHeaderColumnsEvent;
use TYPO3\CMS\Recordlist\Event\ModifyRecordListRecordActionsEvent;
use TYPO3\CMS\Recordlist\Event\ModifyRecordListTableActionsEvent;

class MyEventListener {

    protected LoggerInterface $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
    }

    public function modifyRecordActions(ModifyRecordListRecordActionsEvent $event): void
    {
        $currentTable = $event->getTable();

        // Add a custom action for a custom table in the secondary action bar, before the "move" action
        if ($currentTable === 'my_custom_table' && !$event->hasAction('myAction')) {
            $event->setAction(
                '<button>My Action</button>',
                'myAction',
                'secondary',
                'move'
            );
        }

        // Remove the "viewBig" action in case more than 4 actions exist in the group
        if (count($event->getActionGroup('secondary')) > 4 && $event->hasAction('viewBig')) {
            $event->removeAction('viewBig');
        }

        // Move the "delete" action after the "edit" action
        $event->setAction('', 'delete', 'primary', '', 'edit');
    }

    public function modifyHeaderColumns(ModifyRecordListHeaderColumnsEvent $event): void
    {
        // Change label of "control" column
        $event->setColumn('Custom Controls', '_CONTROL_');

        // Add a custom class for the table header row
        $event->setHeaderAttributes(['class' => 'my-custom-class']);
    }

    public function modifyTableActions(ModifyRecordListTableActionsEvent $event): void
    {
        // Remove "edit" action and log, if this failed
        $actionRemoved = $event->removeAction('unknown');
        if (!$actionRemoved) {
            $this->logger->warning('Action "unknown" could not be removed');
        }

        // Add a custom clipboard action after "copyMarked"
        $event->setAction('<button>My action</button>', 'myAction', '', 'copyMarked');

        // Set a custom label for the case, no actions are available for the user
        $event->setNoActionLabel('No actions available due to missing permissions.');
    }

}

Please have a look at the concrete implementation for a list of all available methods and their functionalities.

Impact

The new PSR-14 events can be used to modify various parts within the RecordList module in an object-oriented way.
