Question

Anyone has any idea how to add some custom options to an entity field type in a nice and clean way? e.g

->add('groups', 'entity', array(
                'class' => 'MyBundle:Groups',
                'multiple' => 'true',
                'query_builder' => function(GroupsRepository $er) {
                            return $er->createQueryBuilder('g')
                                ->orderBy('g.name', 'ASC');
                        }))

Let’s say that query builder returns “Group1”, “Group2” and “Group3”. What I want is to “inject” another option called “Any Group” for example.

Thanks,Stelian

The EntityType is a child of the ChoiceType. So, you have access to the same options.

->add('groups', 'entity', array(
    'class' => 'MyBundle:Groups',
    'multiple' => 'true',
    'query_builder' => function(GroupsRepository $er) {
        return $er->createQueryBuilder('g')->orderBy('g.name', 'ASC');
     },
     'empty_value' => 'Any group',
))
