你好我做的例子link我使用FosUserBundle扩展它，所以任何登录用户都与文件表有关系。但我不想去多文件上传。我查了一些关于它的帖子但是不能让这个工作。我发现有人认为要创建自定义验证器link post here。我的代码仍然没有工作，所以我请求帮助如何更改我的文件以使其工作。

和控制器
public function createAction(Request $request)
{
$entity = new File();
$form = $this->createCreateForm($entity);
$form->handleRequest($request);
if ($form->isValid()) {
//przypisanie zalogowanego uzytkownika
$entity->setUser(
$this->get('security.context')->getToken()->getUser()
);
// $file = $form['file']->getData();
$entity->setOrginalName($form['file']->getData()->getClientOriginalName());//pobranie z formularza nazwy pliku i przypsanie go do bazy danych
// print_r($entity);
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('file_show', array('id' => $entity->getId())));
}
return $this->render('FelekFosBundle:File:new.html.twig', array(
'entity' => $entity,
'form' => $form->createView(),
));
}
那么任何建议如何改变它？我认为很好的解决方案是将foreach文件从传递到实体并处理它，仍然不知道我该怎么办....
