Symfony2 FOSUserbundle add user to group - symfony

Question

i'm using FOSUserBundle Groups.
Now i want to add the groups to my user (when adding a new)
I tried to load the groups to my form but failed.
Here the form:
$builder
->add('enabled','checkbox',array(
'required' => false))
->add('locked','checkbox',array(
'required' => false))
->add('username','text',array(
'required' => true))
->add('email','email',array(
'required' => true))
->add('password','password',array(
'required' => true))
->add('roles', 'choice', array(
'choices' => array('ROLE_ADMIN' => 'Admin', 'ROLE_USER' => 'Benutzer'),
'required' => true,
'multiple' => true
))
->add('groups', 'choice',array(
'choices' => $this->getGroups(),
'multiple' => true
))
->add('save','submit')
;
}
Also i tried
$builder
->add('enabled','checkbox',array(
'required' => false))
->add('locked','checkbox',array(
'required' => false))
->add('username','text',array(
'required' => true))
->add('email','email',array(
'required' => true))
->add('password','password',array(
'required' => true))
->add('roles', 'choice', array(
'choices' => array('ROLE_ADMIN' => 'Admin', 'ROLE_USER' => 'Benutzer'),
'required' => true,
'multiple' => true
))
->add('groups', 'collection', array(
'type' => 'choice',
))
->add('save','submit')
;
Thanks for your help :)

Answer 1

I now get the output with:
->add('groups','entity',array(
'class' => 'UniteUserBundle:usergroup' ,
'property' => 'name' ,
'multiple' => true ,
))
Not the next problem... it don't persist to my table 'fos_user_user_group' :(

Have you tried creating a GroupType and instantiating that type in the collection?
->add('groups', 'collection', array(
'type' => new Name\Space\To\GroupType(),
))
For example your GroupType might look like the following code. Notice it's mapped to the Group entity.
<?php
namespace Name\Space\To\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class GroupType extends AbstractType
{
public $group;
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('group', 'hidden', array(
'error_bubbling' => false,
'required' => false,
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Name\Space\To\Entity\Group',
));
}
public function getName()
{
return 'namespaceto_grouptype';
}
}
