我想要 createForm 但 symfony 不加载我的顶级表单:
这是我的代码:
在我的 frontend.html.twig 中:
{% render "NewsletterBundle:Default:form" %}
在 NewsletterBundle/Form/NewsletterUserType.php 中:
<?php
namespace LoPati\NewsletterBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use JMS\DiExtraBundle\Annotation\Service;
use JMS\DiExtraBundle\Annotation\Tag;
/**
* @Service("lopati.form.newsletter_user")
* @Tag("form.type", attributes = { "alias" = "mp_newsletter_user" })
*/
class NewsletterUserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('email')
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'LoPati\NewsletterBundle\Entity\NewsletterUser'
));
}
public function getName()
{
return 'mp_newsletter_user';
}
}
在 NewsletterBundle/Controller/DefaultController.php 中:
<?php
namespace LoPati\NewsletterBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use LoPati\NewsletterBundle\Entity\NewsletterUser;
class DefaultController extends Controller
{
/**
* @Template()
*/
public function formAction(Request $request)
{
$newsletterUser = new NewsletterUser();
$form = $this->createForm('mp_newsletter_user', $newsletterUser);
return array('form' => $form->createView());
}
}
在 NewsletterBundle/Resources/views/Default/form.html.twig
<form action="" method="post" class="newsletter">
{{ form_widget(form.email) }}
{{ form_widget(form._token) }}
<button type="submit">newsletter</button>
</form>
这是错误:
渲染模板期间引发异常(“无法加载类型“mp_newsletter_user””)
什么时候出问题?
谢谢
