我有两个类 User.php 和 Group.php，它们是从 fosuserbundle 中定义的类扩展而来的。
除此之外，我在它们之间有一个 ManyToMany 关系。
该应用程序的想法是，当我添加新用户时，我会为用户分配一个或多个组(我正在使用 Material 设计多选选项)。当用户没有分配任何组时(例如，当组选项为空时)，就会出现问题。我在控制台中收到此 javascript 错误:
An invalid form control with name='user[groups][]' is not focusable.
所以要解决这个问题，我需要为组字段提供一个默认值。如果未选择组，如何设置默认用户组？我的类(class)定义如下。
UserType.php
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add(
'username',
null,
array(
'attr' => array(
'placeholder' => 'username'
),
))
->add(
'email',
null,
array(
'attr' => array(
'placeholder' => 'email'
),
))
/*->add('groups', EntityType::class, array(
'class' => 'AppBundle\Entity\Group',
'choice_label' => 'name',
'expanded' => false,
'multiple' => false
)) */
->add('groups', EntityType::class, array(
'class' => 'AppBundle\Entity\Group',
'choice_label' => 'name',
'attr'=>array(
'class' => 'mdb-select'
),
'multiple' => true,
))
->add('plainPassword', RepeatedType::class, array(
'invalid_message' => 'Les mots de passe doivent être identiques.',
'first_options' => array('label' => 'Mot de passe'),
'second_options' => array('label' => 'Répétez le mot de passe'),
))
//<input id="input-id" type="file" class="file" multiple data-show-upload="false" data-show-caption="true">
->add('enabled', null, array(
'required' => false,
))
->add('imageFile',VichFileType::class, [
'required' => false,
'download_link' => true,
'attr'=>array(
'type' => 'file',
'onchange' => 'loadFile(event)'), // not mandatory, default is true
])
;
}
GroupEntity.php
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('roles', CollectionType::class, array(
'entry_type' => ChoiceType::class,
'entry_options' => array(
'attr' => array(
'class'=>'mdb-select colorful-select dropdown-default'
),
'choices' => array(
'Admin' => 'ROLE_ADMIN',
'USER' => 'ROLE_USER',
),
)
))
;
}

最佳答案
创建表单时需要传入默认数据。例如，在您的 Controller 中，您将拥有:
$user = new User();
// Add default groups to the $user
// ...
$form = $this->createForm(UserType::class, $user);
$form->handleRequest($request);
if ($form->isValid()) {
$data = $form->getData();
// ...
}
