我有一个Symfony表单类型类,如下所示:
class FeedFilterType extends AbstractType
{
/**
* @var UserProvider
*/
protected $userProvider;
/**
* @var UserRepository $userRepository
*/
protected $userRepository;
public function __construct(UserProvider $userProvider, UserRepository $userRepository)
{
$this->userProvider = $userProvider;
$this->userRepository = $userRepository;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('creators', EntityType::class, [
'class' => User::class,
'choices' => $this->userRepository->getCreatorsSubscribedToByUser($this->userProvider->getCurrentUser()),
'choice_label' => 'name',
'required' => false,
'multiple' => true,
'expanded' => true
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array());
}
}
它可以正常工作,因为它可以带回用户数组,但是当我将其添加到树枝时,例如:
{{ form_widget(feedFilterForm.creators) }}
它是这样的:
我可以从结果实体数组中手动构建一个选择下拉列表,但是Symfony是否有一个内置的select DOM html类型,它是从表单返回的实体数组产生的?
