Question

Currently i develop an rest-api-app with symfony2 and doctrine2. My API should has the functionality to filter the results by an querystring.
For example, the following url:
http://example.com/api/users?orderBy=username%20DESC&limit=20

I can parse the querystring with parse_str($this->getRequest()->getQueryString(), $queryString); to an assoc array.
Is there any function that i can commit the array and doctrine selects the corresponding results? Something like $users = $this->getDoctrine()->getRepository('UserBundle:User')->findByQueryString($queryString);

As AdrienBrault said don’t use parse_str instead put this in your controller:

$orderBy = $this->get('request')->query->get('orderBy');
$limit = $this->get('request')->query->get('limit');
$rep = $this->getDoctrine()->getRepository('UserBundle:User');
$users = $rep->findLimitOrderBy($orderBy, $limit);

And inside your user repository class:

public function findLimitOrderBy($orderBy, $limit)
{
$query = $this->getEntityManager()
    ->createQuery('
    SELECT u FROM UserBundle:User u
    ORDER BY u.'.$orderBy
    )
    ->setMaxResults($limit);

    return $query->getResult();
}
