动态表单类约束不起作用-Symfony 2.7

Question

这是我的表单类，当我要创建动态表单约束不起作用时，我正在向该表单提交请求数据，以进行“类型”验证工作。 含义约束不适用于动态形式。

      class NotesType extends AbstractType
        {
            /**
             * @param FormBuilderInterface $builder
             * @param array $options
             */
            public function buildForm(FormBuilderInterface $builder, array $options)
            {
                $validation_group = array('groups' => array('note'));

                $builder->add('type', 'text', array(
                    'required' => true,
                    'constraints' => array(new NotBlank($validation_group))
                ));

                $builder->addEventListener(
                    FormEvents::SUBMIT,
                    function (FormEvent $event) {
                        $form = $event->getForm();

                        $formData = $form->getExtraData();

                        if ($formData['type'] === 'note') {
                            $form->add('title', 'text', array(
                                'required' => true,
                                'constraints' => array(
                                    new NotBlank()
                                )))
                                ->add('description', 'text', array(
                                    'required' => true,
                                    'constraints' => array(
                                       new NotBlank()

                                    )));
                        } 

             public function configureOptions(OptionsResolver $resolver)
              {
                    $resolver->setDefaults(array(
                     'data_class' => 'NotesManagerBundle\Entity\Notes',
                     'csrf_protection' => false,
                     'allow_extra_fields' => true,
                      'validation_groups' => array('note')
                    ));
             }

}

验证组是否存在此问题？

Answer 1

是的，您应该在title和description字段中添加适当的验证组事件
