Symfony2: Getting the list of user roles in FormBuilder

Question

I\'m making a form for user creation, and I want to give one or several roles to a user when I create him.

How do I get the list of roles defined in security.y

This is not exactly what you want but it makes your example working:

use Vendor\myBundle\Entity\User;

public function buildForm(FormBuilder $builder, array $options)
{
    parent::buildForm($builder, $options);

    // add your custom fields
    $user = new User();
    $builder->add('regionUser');
    $builder->add('roles' ,'choice' ,array('choices' => User::getRolesNames(),
            'required'  => true,
    ));
}

But regarding getting your Roles from an entity, maybe you can use entity repository stuff to query the database.

Here is a good example to get what to want using the queryBuilder into the entity repository:

public function buildForm(FormBuilder $builder, array $options)
{
    parent::buildForm($builder, $options);

    // add your custom fields
    $user = new User();
    $builder->add('regionUser');
    $builder->add('roles' ,'entity' array(
                 'class'=>'Vendor\MyBundle\Entity\User',
                 'property'=>'roles',
                 'query_builder' => function (\Vendor\MyBundle\Entity\UserRepository $repository)
                 {
                     return $repository->createQueryBuilder('s')
                            ->add('orderBy', 's.sort_order ASC');
                 }
                )
          );
}
