即使我有LifecycleCallbacks注释，symfony2 @ORM\HasLifecycleCallbacks中的The file could not be found.也没有被执行。我想按照http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html#using-the-id-as-the-filename中提供的示例进行操作。我的目标是将文件保存在文档ID下。
die("TEST");信息。upload() function命令添加到/**
* @Route("app/documents/add/", name="app_documents_add")
*/
public function addAction(Request $request)
{
/**
* This code is aimed at checking if the book is choseen and therefore whether any further works may be carried out
*/
$session = new Session();
if(!$session->get("App_Books_Chosen_Lp")) return new RedirectResponse($this->generateUrl('app_listbooks'));
// Authorization goes here
$documents = new Documents();
$form = $this->createForm(new DocumentsType(), $documents);
$form->add('save', 'submit', array('label' => 'Dodaj dokument'));
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
//$documents->upload();
$book = $em->getReference('AppBundle:Books', $session->get("App_Books_Chosen_Lp"));
if( $book ) $documents->setBook($book);
else die ("CRITICAL ERROR: addAction - Bad book id");
$em->persist($documents);
$em->flush();
}
return $this->render('AppBundle:Documents:adddocuments.html.twig', array('form' => $form->createView()));
}
但似乎它永远不会被执行，因为结果只是表单页面被重新加载了上述错误。 我想问你一些建议可能是什么原因导致upload（）函数没有被执行？

为什么upload（）函数没有被执行的答案非常简单 - 表单被标记为无效。现在我正在寻找帮助，为什么会发生这种情况（The file could not be found while using LifecycleCallbacks）
