Best practice to add Event Listener to Table

[Todor Iliev]

Hi friends,
What is the best way to add Event Listener to Table?

I would like to add listener to handle "onTableAfterStore" event.

I can do it in the table constructor (look the code below), as Behaviour Plugin or Observer.

Code: Select all

use Joomla\CMS\Table\Table;
use Joomla\Database\DatabaseDriver;

class ItemTable extends Table
{
    /**
     * @param DatabaseDriver $db
     */
    public function __construct(DatabaseDriver $db)
    {
        parent::__construct('#__docs_items', 'id', $db);

       // Registering Closure Listeners
        $this
            ->getDispatcher()
            ->addListener('onTableAfterStore',
                function ($event) {
                    //...
                }
        );

        // Registering Object Listeners
        $this
            ->getDispatcher()
            ->addListener(new ContentListener);
    }
}

Thank you in advance for your answers!

I have made trigger functions inside the db

Would an onContentAfterSave plugin be suitable? There are some examples in use.

[Todor Iliev]

Content plugins are suitable for model events such the admin model.

Behavior plugins are suitable for table events.

I would like to avoid creation of a plugin because I do not need to manage it by the extension manager.

It seems I can also use postSaveHook from the form controller for my purpose.

I found a solution that works for me in the new version of Joomla Framework Event Package.

I did event subscriber and added it to the event dispatcher in the table constructor.
