Symfony3嵌入式表单验证不起作用
Symfony3嵌入式表单验证不起作用
提问于 2017-07-07 10:01:24
我有一个过滤器和FilterCollection对象。FilterCollection保存一组过滤器，就像名称所指示的那样。现在我需要验证所有内容，所以我创建了一个FilterType和FilterTypeCollection表单。在FilterCollectionType中有：
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('filters', CollectionType::class, array(
'entry_type' => FilterType::class
));
}在FilterCollection定义中，我有以下内容：
/**
* @var array
* @Assert\Valid()
*/
private $filters = [];我创建了一个paramConverter，以便将请求中的元素转换为FilterCollection元素。在apply方法中，我尝试使用以下方法验证所有内容：
public function apply(Request $request, ParamConverter $configuration)
$filterCollection = new FilterCollection();
$form = $this->formFactory->create(
FilterTypeCollection::class,
$filterCollection
);
$form->submit($request->query->all());
if ($form->isSubmitted() && $form->isValid()) {
$request->attributes->set($configuration->getName(), $filterCollection);
return true;
} else {
throw new FormValidationException($form);
}
}我原以为验证不仅会验证FilterCollection，而且还会验证过滤器。但是我在过滤器定义中的验证是不起作用的，即使我的验证应该失败，它仍然会通过。我认为验证器没有传递过滤器元素。
知道会发生什么吗？

我终于让它开始工作了。也许您和我犯了同样的错误，忘记在configureOptions中添加formType。
无论如何，下面是工作的代码(在Symfony 3.3的新安装上)
DefaultController.php
<?php
namespace AppBundle\Controller;
use AppBundle\Entity\Filter;
use AppBundle\Entity\FilterCollection;
use AppBundle\Form\FilterCollectionType;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
/**
* @Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
// add first filter, so we don't have to implement the collection javascript etc to test quickly
$collection = new FilterCollection();
$collection->filters[] = new Filter();
$form = $this->createForm(FilterCollectionType::class, $collection);
$form->handleRequest($request);
if ($form->isSubmitted()) {
if ($form->isValid()) {
echo "valid input"; // we don't want to see this ;)
}
}
// replace this example code with whatever you need
return $this->render('default/index.html.twig', [
'form' => $form->createView()
]);
}
}Filter.php
<?php
namespace AppBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Filter {
/**
* @var string
* @Assert\NotBlank()
* @Assert\Regex(pattern="/[0-9]+/")
*/
public $name;
}FilterCollection.php
<?php
namespace AppBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class FilterCollection {
/**
* @var Filter[]
* @Assert\Valid()
*/
public $filters = [];
}FilterType.php
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class FilterType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name', TextType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => 'AppBundle\Entity\Filter'
]);
}
}FilterCollectionType
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class FilterCollectionType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('filters', CollectionType::class, [
'entry_type' => FilterType::class,
]);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => 'AppBundle\Entity\FilterCollection',
]);
}
public function getName()
{
return 'app_bundle_filter_collection_type';
}
}注意:我没有像你那样做ParamConverter，但这似乎与问题无关。您可以轻松地更改代码以使用ParamConverter。
