将验证组设置为symfony 2中的嵌入表单

Question

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

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

这个对我有用

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')
        ));
    }

要根据底层数据使用它,您可以将该代码放在事件侦听器上:

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());
                }
            }
    );
}
