Solution:
$where = '';
$userid = $this->getUser()->getId();
if (!$this->get('security.context')->isGranted('ROLE_ADMIN')){
$where = ' and u.id = ' . $userid;
}
$form->add('user', 'entity',
array(
'label' => 'نانم کاربری',
'class' => 'DotArtBundle:User',
'property' => 'name',
'query_builder' => function(EntityRepository $er) use ($where){
return $er->createQueryBuilder('u')->where('u.type = 1 '.$where);
}
)
)
