Symfony2：表单收集的验证不起作用 [英] Symfony2: Validation of form collection does not work

问题描述

可能重复：

当实体关系/协会时，Symfony2验证无效

Symfony2 validation doesn’t work when Entity Relationships/Associations

我有一个Form PageFormType，只有一个名为entries且没有数据类的字段。

I have a Form PageFormType, that has just one field named "entries" and no data class.

public function buildForm(FormBuilderInterface $builder, array $options) {

  $builder->add('entries', 'collection', array('type' => new EntryFormType() );
}

public function setDefaultOptions(OptionsResolverInterface $resolver) {
    $resolver->setDefaults(array('data_class' => null  ));
}

表单的设置非常棒，我看到每个条目和EntryFormTypes的每个字段都呈现，但是当validationg我的PageFormType时，它总是有效的。单个EntryFormType的验证将有效，但是我想立刻验证所有的嵌入表单。

The setup of the form works great, I see every entry and every field of the EntryFormTypes rendered, but when validationg my PageFormType, it is always valid. Validation of a single EntryFormType would work, but I like to validate all my embedded forms at once. Is this somehow possible?

推荐答案

您必须为表单指派验证（请参阅： http://symfony.com/doc/current/book/forms.html#adding-validation ） 。在你的情况下，你可能想要这样的东西，使用有效约束 ：

You have to assign validation to your form (see: http://symfony.com/doc/current/book/forms.html#adding-validation). In your case you probably want something like this, using the Valid-Constraint:

use Symfony\Component\Validator\Constraints\Valid;

...

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $collectionConstraint = new Collection(array(
        'entities' => new Valid(),
    ));

    $resolver->setDefaults(array(
        'validation_constraint' => $collectionConstraint
    ));
}
