我想要createForm,但symfony没有加载我的顶级表单:
这是我的代码:
在我的frontend.html.twig中:
{% render "NewsletterBundle:Default:form" %}
in NewsletterBundle / Form / NewsletterUserType.php:
<?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
中<form action="" method="post" class="newsletter">
{{ form_widget(form.email) }}
{{ form_widget(form._token) }}
<button type="submit">newsletter</button>
</form>
这是错误:
在渲染模板期间抛出了异常 (“无法加载类型”mp_newsletter_user“”)
什么时候出现问题?
谢谢

答案 0 :(得分:4)
您已将表单定义为服务,因此,请将创建表单更改为:
// $form = $this->createForm('mp_newsletter_user', $newsletterUser);
$form = $this->createForm($this->get('mp_newsletter_user'), $newsletterUser); // you need use $this->get to get a service
这也应该有效:
$this->createForm(new \LoPati\NewsletterBundle\Form\NewsletterUserType(), $newsletterUser);
