        $item = new Item();
        $form = $this->createForm(AddPropertyType::class, $item);

            $arrayItemsMedia = explode(',',$form->get("arrayIdMedia")->getData());
            foreach ($arrayItemsMedia as $key => $value) {
                $mediaObject = $this->repoAttachment->findOneBy(['id' => intval($value)]);
                $item->addAttachment($mediaObject);
            }

            $entityManager->persist($item);
