PHP发布请求停止与空白页

Question

我有一个窗体与嵌入式文件窗体（新闻和NewsFiles集合）。在我的本地主机上一切正常：新闻和NewsFiles实体持续存在，文件上传。 但是当我尝试添加文件时，生产服务器上的发布请求被停止。文件上传，实体不存在于数据库中，发布请求停止状态：302找到并返回空白页，而不是重定向到下一页。

public function createAction(Request $request) { 

    $entity = new News(); 
    $form = $this->createCreateForm($entity); 
    $form->handleRequest($request); 

    if ($form->isValid()) { 

     $em = $this->getDoctrine()->getManager(); 

     $em->persist($entity); 

     // PROBLEM APPEARS HERE - WHEN TRY TO FLUSH 
     $em->flush(); 


     $this->get('session')->getFlashBag()->add(
       'success', 'Wykonano pomyślnie!' 
     ); 

     return $this->redirect($this->generateUrl('website_admin_panel_news')); 
    } 

    return $this->render('WebsiteNewsBundle:News:new.html.twig', array(
       'entity' => $entity, 
       'form' => $form->createView(), 
    )); 
} 

当我尝试添加新闻实体（没有文件）时没有问题。我在编辑实体时也是如此。

日志： logs

INFO - Matched route "news_update" (parameters: "_controller": "Website\NewsBundle\Controller\NewsController::updateAction", "id": "6", "_route": "news_update") 
DEBUG - Read SecurityContext from the session 
DEBUG - Reloading user from user provider. 
DEBUG - Username "admin" was reloaded from user provider. 
DEBUG - Write SecurityContext in the session 

我认为这个问题是在服务器端，我会写信给管理员，但他不是专家，所以我需要建议他什么，他必须改变。 .. 有任何想法吗？可能是超时问题？

编辑： 我有更多的信息。这个问题发生在move（）函数中。这不是超时问题，因为我试图发送一个小文件（1px - 539字节），但它仍然不能完成这项工作。 这是我的实体上传：

好吧，我已经发现了这是怎么回事。 我的prod服务器不接受chmod功能，它被锁定。 Symfony2文件： /vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/File/UploadedFile.php has move（）函数 - >我已经删除了chmod使用，并且everythning工作正常。

这里是移动（）函数修改后：

public function move($directory, $name = null) 
    { 
     if ($this->isValid()) { 
      if ($this->test) { 
       return parent::move($directory, $name); 
      } 

      $target = $this->getTargetFile($directory, $name); 

      if (!@move_uploaded_file($this->getPathname(), $target)) { 
       $error = error_get_last(); 
       throw new FileException(sprintf('Could not move the file "%s" to "%s" (%s)', $this->getPathname(), $target, strip_tags($error['message']))); 
      } 

      return $target; 
     } 

     throw new FileException($this->getErrorMessage()); 
    }
