    }
    public function removeFile()
    {
        $tmp = $this->getUploadRootDir().'/'.$this->id.'.'.$this->path;
        unlink($tmp);
    }


}

在控制器中我有

public function deleteAction($id)
{
    $em= $this->getDoctrine()->getManager();

    $pers= $em->getRepository('BackUserBundle:User')->find($id);
    $tmp = $pers->getFile();
    if($tmp != NULL)
    {
        $pers->removeFile();
        $pers->setFile();
        $em->persist($pers);
        $em->flush();
    }


    return new RedirectResponse($this->get('router')->generate('fos_user_profile_show'));
}

它正常工作，删除文件并清除路径字段。

我现在的问题是创建一个更改路径字段和文件的函数。

有人帮助我吗？谢谢你：）

我认为你几乎拥有所需的一切，请遵循官方文件：

http://symfony.com/fr/doc/current/cookbook/doctrine/file_uploads.html

在您的控制器中：

public function uploadAction()
{
    $user= new User();
    $form = $this->createFormBuilder($user)
        ->add('file')
        ->getForm()
    ;

    if ($this->getRequest()->isMethod('POST')) {
        $form->handleRequest($this->getRequest());
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $user->upload();
            $em->persist($user);
            $em->flush();

            $this->redirect($this->generateUrl(...));
        }
    }

    return array('form' => $form->createView());
}

您必须稍微更改实体中的上传功能，以便在移动后保存文件的路径。

user.php的

$this->getFile()->move(
    $this->getUploadRootDir(),
    $this->id.'.'.$this->getFile()->guessExtension()
);
$this->path = $this->getUploadRootDir(),
    $this->id.'.'.$this->getFile()->guessExtension();

并且不要忘记上传操作的路由。

从FosUserBundle编辑用户实体上的字段文件
