symfony - Create repository action from form selected items in Symfony2? -

edit found how data

    $filter_form->handlerequest($request);      if ($filter_form->isvalid()) {         $users = $filter_form->get('users')->getviewdata();         $tags = $filter_form->get('tags')->getdata();          $links = $em->getrepository('lancrmbundle:link')->findfiltered($users, $tags);     } else {         $links = $em->getrepository('lancrmbundle:link')->findby(             array(),             array('id' => 'desc')         );     } 

now have create findfiltered method in repository.

but don't know how make working.

public function findfiltered($users, $tags) {     $querybuilder = $this->createquerybuilder('l');      $querybuilder->orderby('l.id', 'desc');      if($users) {         ???     }      if($tags) {         ???     }      return $querybuilder->getquery()->getresult();  } 

i hope understandable, if not not hesitate ask me more information.

thank in advance.

you didn't specify associations types should like:

return $this->_em     ->createquery(         'select l lancrmbundle:link '.         'where l.user in (:users) , l.tag in (:tags) '.         'order l.id desc')     ->setparameter('users', $users)     ->setparameter('tags', $tags)     ->getresult();
