symfony - How to use Repository custom functions in a FormType -

-

the problem i'm facing have create selectbox in form holds parent entities (category entity). managed with:

$builder->add('parent', 'entity', array(                 'class' => 'kprcentarzdravljabundle:category',                 'query_builder' => function($repository) use ($param, $catid) {                                          return $repository->createquerybuilder('p')                                                 ->where('p.id != :id , p.parent = :parent')                                                 ->setparameters(array('id' => $param, 'parent' => $catid));},                 'property' => 'name',                 'required' => false,                 'attr'   =>  array('data-placeholder' => '--izaberite opciju--'),                 ));

as u can see pass 2 arguments first current category.id(a category cant own parent) , second parent id, because want children parent. works nice doesn't give me parents children's children. created categoryrepository recursive function returns children:

<?php  namespace kpr\centarzdravljabundle\entity;  use doctrine\orm\entityrepository; use doctrine\common\collections\arraycollection; use kpr\centarzdravljabundle\entity\category;  class categoryrepository extends entityrepository { public function findbyparenting($parent) {     $qb = $this->getentitymanager()->createquerybuilder();      $qb->add('select', 'cat')        ->add('from', 'kprcentarzdravljabundle:category cat')        ->add('where', 'cat.parent = :parent')        ->setparameter('parent', $parent);     // $qb instanceof querybuilder     $query = $qb->getquery();     $results = $query->getresult();     foreach($results $result){         if($result->getparent()){             $newresult = $this->findbyparenting($result->getid());             $results = array_merge($results, $newresult);         }     }     return $results;  } }

how can use findbyparenting($parent) function in entity field?
