symfony2 form multiple select with arraycollection

Question

I would like to create a form to edit my users. Users and roles connected with ManyToMany. In UserUsers entity I have a $roles variable which is ArrayCollection:

public function __construct()
{
    $this->roles = new ArrayCollection();
}

On my form I would like to add roles to my users via multiple select form element. In my user form:

public function buildForm( FormBuilderInterface $builder, array $options ) {
    $builder->add( 'username' )
            ->add( 'password', 'repeated', array( 
                    'type' => 'password',
                    'mapped' => false,
                    'required' => false,
                    'first_options' => array( 
                            'label' => 'Password' ),
                    'second_options' => array( 
                            'label' => 'Repeat Password' ) ) )
            ->add( 'roles', 'choice', array( 
                    'mapped' => false,
                    'multiple' => true ) );
}

Now my multiple select is empty.

If I turn mapped to true, I got an error message:

UserRoles could not be converted to int in...

I've tried a lots of ways, but I could not solve this problem correctly.

All elements in $roles ArrayCollection is an entity (UserRoles). — lordjancso

For a choice of entities you should use the special choice field type 'entity' (symfony.com/doc/current/reference/forms/types/entity.html). For an example see my answer to a similar question - stackoverflow.com/questions/13519961/… — redbirdo

Okay, I changed roles like this: $builder->add( 'roles', 'entity', array( 'class' => 'AcmeUserBundle:UserRoles', 'multiple' => true, 'property' => 'name' ) ); Then I got an error message: Expected argument of type "Doctrine\Common\Collections\Collection", "array" given — lordjancso

That's odd, as ArrayCollection implements Doctrine\Common\Collections\Collection. Is it possible that roles() is reassigned to an array elsewhere? Or that ArrayCollection is not resolving to the doctrine class? — redbirdo

For a choice of entities you should use the special choice field type 'entity' (see Symfony manual for entity field type). For an example see my answer to a similar question. If you get further errors you may also find this question on Role Interface and Manage Roles helpful.

for the fosuserbundle I do it like that:

        $builder->add('roles', 'choice', array(
        'multiple' => true,
        'choices' => array(
            'ROLE_USER' => 'User',
            'ROLE_AUTHOR' => 'Autor',
            'ROLE_MODERATOR' => 'Moderator',
            'ROLE_ADMIN' => 'Admin'
        ),
        'label' => 'Rollen',
        'required' => true
    ));

This would be good, but I store the roles in the database and when I open the users to edit, I want to be selected those roles which are assigned to the current user.

I have already understood and I strongly recommend the use of FOSUserBundle - Because of the security. There you can store multiple roles to a user. This is the end what you want.
