Question

我正在尝试使用ajax调用上传文件，但是当我去保存我的保存只与anagrafic的关系。我声明如果我试图保存正常工作。

好像它没有加载对象UploadFile！我根据symfony cookbook http://symfony.com/doc/2.1/cookbook/doctrine/file_uploads.html创建了表格在我的控制器中

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

    $entity = $em->getRepository('MyBusinessBundle:Anagrafic')->find($id);
    $media = new Multimedia();
    $form = $this->createForm(new MultimediaType(), $media);

    if ($this->getRequest()->isMethod('POST')) {
        $form->bind($this->getRequest());
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();

            $media->setAnagrafic($entity);
            $em->persist($media);
            $em->flush();

            $response = new Response();
        $output = array('success' => true);
        $response->headers->set('Content-Type', 'application/json');
        $response->setContent(json_encode($output));
        }
    }

我试着做var_dump的var_dump（$ media）;并返回：

object(My\BusinessBundle\Entity\Multimedia)[337]
  private 'id' => null
  private 'percorso' => null
  private 'alt' => null
  private 'type' => null
  public 'file' => null
  private 'anagrafic' => null

我不明白为什么.. 但是如果我使用插件jquery https://github.com/blueimp/jQuery-File-Upload传递文件，我会得到正确的文件，我可以继续使用cookbook的方法！我的解决方案：

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

    $entity = $em->getRepository('MyBusinessBundle:Anagrafic')->find($id);
    $media = new Multimedia();
    $form = $this->createForm(new MultimediaType(), $media);

    $request = $this->getRequest();
    if ($request->isMethod('POST')) {
        $form->bind($request);
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $media->setAnagrafic($entity);
            $em->persist($media);
            $em->flush();

            if ($request->isXmlHttpRequest()) {
                $response = new Response();
                $output = array('success' => true);
                $response->headers->set('Content-Type', 'application/json');
                $response->setContent(json_encode($output));

                return $response;
            } else {
                return $this->redirect($this->generateUrl('user_img', array('id' => $entity->getId())));
            }

    } else {
    if ($request->isXmlHttpRequest()) {
        $errors = $form->get('file')->getErrors();
        $response = new Response();
        $output = array('success' => false, 'errors' => $errors[0]->getMessage());
        $response->headers->set('Content-Type', 'application/json');
        $response->setContent(json_encode($output));

        return $response;
    }
    }
    }

给定双重调用

将重构 - ＆gt; isXmlHttpRequest（），但这个概念有效！我忘了..如果你将输入文件设置为“多个”，则会对每个文件发出请求！

解决！
