如何从symfony 2控制器中删除嵌入表单中的表单域

我的表格如下:

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')

如何使用$ form-> remove()删除嵌入式表单中的字段?是否可以从控制器中删除嵌入表单的字段?

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。
