Question

我尝试上传图片，但没有任何反应。

用户实体（注意：此实体包含有关用户信息的其他属性）

<?php

namespace Test\BackBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\HttpFoundation\File\UploadedFile;

/**
 * User
 *
 * @ORM\Table()
 * @ORM\Entity
 * @ORM\HasLifecycleCallbacks
 */
class User implements UserInterface
{
    ...

   /**
     * @var string
     *
     * @ORM\Column(type="string", length=255)
     */
    private $path;

    public $file;

    ... 

    public function getAbsolutePath()
    {
       return null === $this->path ? null : $this->getUploadRootDir().'/'.$this->path;
    }

    public function getWebPath()
    {
       return null === $this->path ? null : $this->getUploadDir().'/'.$this->path;
    }

    protected function getUploadRootDir()
    {   
       return __DIR__.'/../../../../web/'.$this->getUploadDir();
    }

    protected function getUploadDir()
    {
       return 'upload/files';
    }

   /**
    * @ORM\PrePersist()
    * @ORM\PreUpdate()
    */
   public function preUpload()
   {
      if (null !== $this->file) {
          $this->path = sha1(uniqid(mt_rand(), true)).'.'.$this->file->guessExtension();
      }
   }

   /**
    * @ORM\PostPersist()
    * @ORM\PostUpdate()
    */
   public function upload()
   {
       if (null === $this->file) {
          return;
       }

       $this->file->move($this->getUploadRootDir(), $this->path);

       unset($this->file);
   }

   /**
    * @ORM\PostRemove()
    */
   public function removeUpload()
   {
       if ($file = $this->getAbsolutePath()) {
           unlink($file);
       }
   }
}

UserType.php：

$builder
    ->add('firstName', 'text', array(
                    'required' => true
                ))
     ->add('lastName', 'text', array(
                    'required' => true
                ))
     ->add('email', 'email', array(
                    'required' => true
                ))
     ->add('job', 'text', array(
                    'required' => false
                ))
     ->add('file', 'file', array(
                    'label' => false,
                    'required' => false,
                    'mapped' => false
                ))
     ;

UserController.php

    public function updateMyAccountAction($id, Request $request)
    {
        $entityManager = $this->get('doctrine')->getManager();

        $user = $this->get('doctrine')
            ->getRepository('TestBackBundle:User')
            ->find($id);

        if (!$user) {
            throw $this->createNotFoundException('Unable to find User entity.');
        }

        $editForm = $this->createForm(new UserType(), $user);

        $editForm->handleRequest($request);

        if ($editForm->isValid()) {

            $entityManager->persist($user);
            $entityManager->flush();

            return $this->redirect($this->generateUrl('my_account', array('id' => $id)));
        }
    }

my_account.html.twig：

<form action="{{ path('my_account_update', { 'id': app.user.id }) }}" method="post" {{ form_enctype(form) }}>
   {{ form_widget(form) }}

   <div class="btn-group">
       <button type="submit" class="btn btn-info">Enregistrer</button>
   </div>
</form>

当我提交表单时，我没有错误，但图片未上传。

编辑：

如果我从构建器中删除'mapped' => false，则会出现此错误：

'Symfony \ Component \ HttpFoundation \ File \ UploadedFile'的序列化不允许

如果我在验证后执行var_dump($user)，则path attribute = NULL

我可以提供简单的代码来上传文件的图像：）

/**
 * @ORM\PrePersist()
 * @ORM\PreUpdate()
 */
public function upload()
{

    if ($this->image instanceof UploadedFile && $this->image != null && $this->image->getRealPath()) {
        $dir = "photos/";
        $name = md5(rand().time()) . "." . $this->image->getClientOriginalExtension();
        $this->image->move($dir, $name);
        $this->setImage($dir.$name);
    };
}

上传图片不起作用
