Teams

Q&A for work

Connect and share knowledge within a single location that is structured and easy to search.

When I do this $builder->add('teams'); it lists all my teams on my form AND an empty choice, so it's possible to have no team or to remove the team (and that behavior is great for what I have to do).

But when I use a query_builder

$builder->add('teams', EntityType::class, array(
                    'class' => Team::class,
                    'query_builder' => function (EntityRepository $er) {
                        return $er->getTeamsNotRestrictedByAdmin();
                    'choice_label' => '_name'
it returns the entities I want but I don't have that null choice anymore. How could I get it back properly ?
$builder->add('teams', EntityType::class, array(
                    'class' => Team::class,
                    'query_builder' => function (EntityRepository $er) {
                        return $er->getTeamsNotRestrictedByAdmin();
                    'choice_label' => '_name',
                    'required' => false,
                    'empty_data' => ''
