如何在嵌入表单中设置验证组？我有两个实体A和B，每个实体的形式（FormA，FormB）我在FormB中嵌入FormA

class FormB extends AbstractType {
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('A', new FormA());
    }
    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'Acme\TestBundle\Entity\B',
            'validation_groups'=>function(FormInterface $form) {
                // set validation group for FormA here
             },
            'cascade_validation'=>true
        ));
    }
}

如何从FormB设置FormA的验证组？

Answer 1

它对我有用

class FormB extends AbstractType {
    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('A', new FormA(), array('validation_groups' => array('yourValidationGroup')));
    }
    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'Acme\TestBundle\Entity\B',
            'cascade_validation'=>true
        ));
    }
}

还在FormB-> setDefaultOptions中定义验证组。它将验证组应用于所有子表单。

    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'Acme\TestBundle\Entity\B',
            'cascade_validation'=>true,
            'validation_groups' => array('yourValidationGroup')
        ));
    }

要根据基础数据使用它，您可以将该代码放在事件监听器上：

public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder->addEventListener(
            FormEvents::POST_SET_DATA,
            function(FormEvent $event) {
                $form=$event->getForm();
                /**
                 * @var ContactDetail $detail
                 */
                $entity=$form->getData();
                if($entity->getA()->isRequired()){
                    $form->add('A', new FormA(), array('validation_groups' => array('yourValidationGroup')));
                } else {
                    $form->add('A', new FormA(), array());
                }
            }
    );
}

Answer 2

属性class Profile { /** * @var Address * * @Assert\Valid() */ private $address; }为deprecated in Symfony 2.8，将在Symfony 3.0中删除。要使用filter-branch，您应该使用@Assert\Valid constraint。

git rm --cached

P.S。注意：链接提供Symfony 2.8版本。
