Symfony 2 render entity select box to radio buttons and check box

Above we have seen how render radio and check box from foreign key select box in symfony1.x version. I updated this post for symfony2 version as well.

Radio Button

Expand option making our work very simple in simfony2. This option will be false in default.

$builder->add('category_id','entity',array('expanded'=>true,'property' => 'name','class' => 'AcmeJobeetBundle:Category','query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('c')->where('c.isActive = :isActive')->setParameter('isActive', '1')->orderBy('c.name', 'ASC');
}));

Checkbox

Multiple option giving this feature. This option will be false in default.

$builder->add('category_id','entity',array('expanded'=>true,'multiple'=>true,'property' => 'name','class' => 'AcmeJobeetBundle:Category','query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('c')->where('c.isActive = :isActive')->setParameter('isActive', '1')->orderBy('c.name', 'ASC');
}));
