Symfony：如何将验证组添加到RepeatedType？

Question

如何将验证组添加到RepeatedType？我想在约束验证期间为特定组启用RepeatedType验证（例如＆＃39; updatePasswords＆＃39;）。

这是我的表格：

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('updatePasswordCheckBox', CheckboxType::class)
            ->add('plainPassword', RepeatedType::class, array(
                'type' => PasswordType::class,
                'first_options' => array('label' => 'Password'),
                'second_options' => array('label' => 'Repeat password'),
                'invalid_message' => "Passwords don't match!",
                'groups' => "updatePasswordChecked",

            ))
            ->add('save', SubmitType::class, array('label' => 'Save'));
    }

更新： 根据密码的状态复选框，将触发相应的验证组：

public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
                'data_class'        => 'ImmoBundle\Entity\User',
                'csrf_protection'   => true,
                'validation_groups' => function(FormInterface $form){
                    $data = $form->getData();

                    if ($data->getUpdatePasswordCheckBox() == 1)
                    {
                        return array('Default', 'updatePasswordChecked');
                    }
                    else
                    {
                        return array('Default', 'update');
                    }
                }
            ));
    }
