Events

There are some events which are triggered while editing or creating entites.

Events available

• araise_table.data_load.pre_load: is triggered before the resultset is loaded
• araise_table.data_load.post_load: is triggered after the resultset is loaded

Using events

In this example, we limit the number of rows returned based on the ?limit=n Parameter.

<?php
// src/araise/TableBundle/EventListener/LimitEventListener.php

namespace araise\TableBundle\EventListener;

use araise\TableBundle\Event\DataLoadEvent;
use araise\TableBundle\Table\Table;

class LimitEventListener
{
    public function limitResultSet(DataLoadEvent $event)
    {
        $table = $event->getTable();

        if ($table->getRequest()->query->getInt('limit') === -1) {
            $table->getQueryBuilder()->setMaxResults(-1);
            $table->getQueryBuilder()->setFirstResult(0);
            return;
        }

        $table->getQueryBuilder()->setMaxResults($table->getRequest()->query->getInt('limit', 25));
        $table->getQueryBuilder()->setFirstResult(($table->getCurrentPage() - 1) * $table->getLimit());
    }
}
