Symfony - 在提交时设置validation_groups会跳过该类型的validation_groups回调

Question

在symfony中，我有一个嵌入其他形式的多阶段表单。其中一些嵌入表单具有动态验证组，通过该validation_groups（以前为setDefaultOptions）方法的configureOptions回调设置。

当通过未设置其validation_groups选项的提交提交表单时，将运行这些回调并使用正确的验证组。但是当我将submit的validation_groups选项设置为具有此回调的类型时，则不会运行回调，并且不会根据需要设置组。

是否需要设置任何选项才能使其正常工作？

$form = $this->createForm(new RegistrationType());
$form->add('Submit1', 'submit', array(
           'validation_groups' => array('Person'),
    ))
    ->add('Submit2', 'submit', array(
           'validation_groups' => array('Contact', 'Address'),
    ))
;

提交按钮验证组优先于Type的验证组。 Form::getClickedButton返回一个绑定到当前表单或其父项的单击按钮。

您描述的案例可以通过将回调而不是普通组传递到提交按钮来解决。 E.g：

$form->add('Submit1', 'submit', array(
       'validation_groups' => function (FormInterface $form) {
           if ($form->isRoot()) {
                return array('Person');
           } else {
                return ($form->getConfig()->getOptions('validation_groups'))();
           }
       },
))
