我有一个表格如下：
class AdminEmployerForm extends AbstractType {
public function buildForm(FormBuilderInterface $builder,array $options) {
$builder
->add('firstName','text')
->add('user',new AdminUserForm());
}
}
class AdminUserForm extends AbstractType {
public function buildForm(FormBuilderInterface $builder,array $options) {
$builder
->add('username','text')
->add('email','text');
}
}
我在控制器中调用AdminEmployerForm,我想从AdminEmployerForm中删除AdminUserForm的电子邮件字段：
$form = $this->createForm(new AdminEmployerForm,$employer);
//i want to do something like $form->remove('email')
解决方法
您必须获取嵌入的表单类型才能从中删除字段.
$form = $this->createForm(new AdminEmployerForm,$employer);
// Get the embedded form...
$adminUserForm = $form->get('user');
// ... remove its email field.
$adminUserForm->remove('email');
不确定您的确切用例,但您可以考虑leveraging form events,因为它可能比在控制器中处理它更理想.
