controller:
/** * @route("app/documents/add/", name="app_documents_add") */ public function addaction(request $request) { /** * code aimed @ checking if book choseen , therefore whether further works may 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())); } documents class:

the answer why upload() function not executed quite easy - form marked invalid. looking why happens (the file not found while using lifecyclecallbacks)
