Question

我有一个带有嵌入式文件格式的表单（新闻和新闻文件集合）。在我的localhost机器上一切正常：新闻和NewsFiles实体仍然存在，文件被上传。但是在生产服务器上，当我尝试添加文件时，请求停止了。文件被上传，实体不存在于db中，post请求停止，状态为：302 Found，它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(),
    ));
}

当我尝试仅添加新闻实体（没有文件）时没有问题。我正在编辑实体时也一样。

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

我认为问题出在服务器端，我会写信给管理员，但他不是专家，所以我需要建议他必须改变什么......有什么想法吗？这可能是超时问题吗？

编辑：我有更多的信息。问题发生在move（）函数中。这不是超时的问题，因为我试图发送小文件（1px - 539字节），但它仍然没有完成这项工作。这是我上传的实体：

好的，我发现了正在发生的事情。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 有move（）函数 - ＆gt;我已经删除了那里的chmod用法，并且每个人都可以正常工作。

这是修改后的move（）函数：

   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());
    }
