如何在嵌入式表单中设置验证组？
我有两个实体A和B,并为每个实体(FormA,FormB)
我在FormB中嵌入FormA
我有两个实体A和B,并为每个实体(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？
解决方法
它适用于我
class FormB extends AbstractType {
public function buildForm(FormBuilderInterface $builder,new FormA(),array('validation_groups' => array('yourValidationGroup')));
}
public function setDefaultOptions(OptionsResolverInterface $resolver) {
$resolver->setDefaults(array(
'data_class' => 'Acme\TestBundle\Entity\B','cascade_validation'=>true
));
}
}
还可以在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',array('validation_groups' => array('yourValidationGroup')));
} else {
$form->add('A',array());
}
}
);
}
