Question

我在Symfony 3中使用表单时遇到一个奇怪的问题。

我的Assert在我的实体文件中不起作用。

在“开发者工具”中，它显示短语，但在视图中，所有内容都是空白的。

<?php

namespace TestBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;
use Symfony\Component\Security\Core\User\UserInterface;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * User
 *
 * @ORM\Table(name="users")
 * @UniqueEntity("name")
 * @UniqueEntity("email")
 * @ORM\HasLifecycleCallbacks()
 */
class User implements UserInterface
{
    /**
     * @Assert\NotBlank()
     * @Assert\NotBlank(message="Please enter your name.")
     */
    private $name;

     /**
     * @Assert\NotBlank()
     * @ORM\Column(type="string", length=50, nullable=false)
     */
    private $sername;

    /**
     * @var string
     * @Assert\NotBlank()
     * @Assert\Email()

    private $email;

    /**

    private $password;

    /**

    private $role;

    /**
     * @var \DateTime
     */
    private $created;

    /**
     * @var integer
     */
    private $id;


    /**

    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**

    public function getName()
    {
        return $this->name;
    }

    /**

    public function setSername($sername)
    {
        $this->sername = $sername;

        return $this;
    }

    /**

     *

    public function getSername()
    {
        return $this->sername;
    }

    /**
     * Set email
     *
     * @param string $email
     *
     * @return User
     */
    public function setEmail($email)
    {
        $this->email = $email;

        return $this;
    }

    /**
     * Get email

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

    /**

     * @return User

    public function setPassword($password)
    {
        $this->password = $password;

        return $this;
    }

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

    /**

     *
     * @return User

    public function setRole($role)
    {
        $this->role = $role;

        return $this;
    }

    /**
     * Get role
     *
     * @return integer
     */
    public function getRole()
    {
        return $this->role;
    }

    /**

     * @param \DateTime $created
     *
     * @return User
     */
    public function setCreated($created)
    {
        $this->created = $created;

        return $this;
    }

    /**
     * Get created
     *
     * @return \DateTime
     */
    public function getCreated()
    {
        return $this->created;
    }

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }
     public function getRoles()
    {
        return array($this->role);
    }

    public function getSalt()
    {
        return null;
    }

    public function eraseCredentials()
    {

    }
    /**
     * Get username
     *
     * @return string
     */
    public function getUsername()
    {
        return null;
    }
}

我的表单操作（我将false设置为false以使用symfony有效选项）：

 public function addAction(Request $request){
  $user = new User();
  $form = $this->createFormBuilder($user)
  ->add('Name', TextType::class,array('required'=> false,'empty_data'  => null))
  ->add('SerName', TextType::class,array('required'=> false,'empty_data'  => null))
  ->add('role', TextType::class,array('required'=> false,'empty_data'  => null))
  ->add('email', EmailType::class,array('required'=> false,'empty_data'  => null))
  ->add('password', RepeatedType::class, array(
            'type' => PasswordType::class,
            'first_name'  => 'pass',
            'second_name' => 'confirm',
            'required' => false,
        ))
  ->add('save', SubmitType::class, array('label' => 'Create Post'))
  ->getForm();
   $form->handleRequest($request);
  if ($form->isSubmitted() && $form->isValid()) {
      //$user = new Users();
      // $form->getData() holds the submitted values
      // but, the original `$task` variable has also been updated
      $password = $form->get('password')->getData();
      $encoder = $this->container->get('security.password_encoder');
      $encoded = $encoder->encodePassword($user,$password);
      $user->setPassword($encoded);
      $user = $form->getData();

      // ... perform some action, such as saving the task to the database
      // for example, if Task is a Doctrine entity, save it!
      $em = $this->getDoctrine()->getManager();
      $em->persist($user);
      $em->flush();
      return $this->redirectToRoute('test_homepage');
  }

  //return $this->render('UserBundle:Default:add.html.twig');
  return $this->render("TestBundle:Default:add.html.twig",array("form"=>$form->createView()));

}

编辑（I PUT VIEW FILE）： 我的观点：

{%extends "principal.html.twig"%}

  {% block body %}
    {{parent()}}
    <h1> {% trans %}New User{% endtrans %}</h1>
  {{ form_start(form,{'attr':{'novalidate':'novalidate','role':'form'}}) }}
       {{ form_label(form.Name,'Username', {'label_attr': {'class': 'foo'}}) }}
       {{ form_widget(form.Name,{'attr':{'class':'form-control'}}) }}
       {{form_errors(form.Name)}}
       {{ form_label(form.SerName,'Last name', {'label_attr': {'class': 'foo'}}) }}
       {{ form_errors(form.SerName) }}
       {{ form_widget(form.SerName,{'attr':{'class':'form-control'}}) }}
       {{ form_label(form.role,'Role', {'label_attr': {'class': 'foo'}}) }}
       {{ form_errors(form.role) }}
       {{ form_widget(form.role,{'attr':{'class':'form-control'}}) }}
       {{ form_label(form.email,'Email', {'label_attr': {'class': 'foo'}}) }}
       {{ form_widget(form.email, {'attr':{'class':'form-control'}}) }}
       {{ form_errors(form.email) }}
       {{ form_label(form.password.pass, "Password", {'attr':{'class':'form-control'}}) }}
       {{ form_errors(form.password) }}
      {{ form_widget(form.password.pass, {'attr':{'class':'form-control'}}) }}

      {{ form_label(form.password.confirm, "Confirm" , {'attr':{'class':'form-control'}}) }}
      {{ form_widget(form.password.confirm, {'attr':{'class':'form-control'}}) }}
       {{ form_widget(form.save, { 'label': 'Create User','attr':{'class':'btn btn-primary'}}) }}
{{ form_end(form) }}
  {% endblock %}

Answer 1

你应该阅读doc about form rendering 在twig模板中，您必须使用

显示错误

{{ form_errors(form.age) }}

或整行（标签，错误信息，inpout）和

{{ form_row(form.age) }}

几乎等于

<div>
    {{ form_label(form.age) }}
    {{ form_errors(form.age) }}
    {{ form_widget(form.age) }}
</div>

在您的情况下，这意味着您必须以这种方式添加form_errors：

   {{ form_label(form.Name,'Username', {'label_attr': {'class': 'foo'}}) }}
   {{ form_widget(form.Name,{'attr':{'class':'form-control'}}) }}
   {{ form_errors(form.Name) }}

断言在我的表单中不起作用
