Php Symfony 2.5中的表单验证

我正在尝试验证联系人表单上的字段，表单本身运行良好，并且正在发布数据，但是我在验证字段时遇到了困难。根据文档，设置验证似乎非常简单，但由于某些原因，它对我不起作用

当我创建bundle时，bundle的config文件夹中没有

validation.yml

，所以我手动创建了它，这就是我的

validation.yml

看起来的样子，它现在非常基本

ClickTeck\ContactBundle\Entity\Enquiry:
    properties:
        name:
            - NotBlank: ~
            - Length:
                min: 2
                max: 50
                minMessage: "Your first name must be at least {{ limit }} characters long"
                maxMessage: "Your first name cannot be longer than {{ limit }} characters long"

这就是

DefaultController

的外观

namespace ClickTeck\ContactBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use ClickTeck\ContactBundle\Entity\Enquiry;
use ClickTeck\ContactBundle\Form\EnquiryType;
use Symfony\Component\HttpFoundation\Request;
class DefaultController extends Controller
{
    public function indexAction(Request $request)
    {
        $enquiry = new Enquiry();
        $form = $this->createForm(new EnquiryType(), $enquiry);

            $form->handleRequest($request);

            if ($form->isValid()) {
                return $this->redirect($this->generateUrl('contact_form'));
            }

        return $this->render('ContactBundle:Default:contact.html.twig', array(
                'form' => $form->createView()
            ));
    }
}

这是我的

Enquiry.php

在

Entity

文件夹中

<?php

    }

        $this->name = $name;

        return $this;
    }

    }

    public function setEmail($email)
    {
        $this->email = $email;

        return $this;
    }

    /**

    public function getEmail()
    {
        return $this->email;
    }

    /**

    }

    public function setBody($body)
    {
        $this->body = $body;

        return $this;
    }

    /**
     * Get body
     *
     * @return string 
     */
    public function getBody()
    {
        return $this->body;
    }

}

namespace ClickTeck\ContactBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class EnquiryType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name');
        $builder->add('email', 'email');
        $builder->add('subject');
        $builder->add('body', 'textarea');
    }

    public function getName()
    {
        return 'contact';
    }

当我提交带有空名称字段的表单时，我没有收到任何错误，如果有人能给我指出正确的方向，我将不胜感激。

这就是解决我问题的方法，在

app/config/config.yml

中，默认情况下验证似乎被关闭，将其更改为以下内容，所有验证工作正常

framework:
    validation:      { enabled: true, enable_annotations: false }
