如何使用已上传的FileType编辑实体？

Question

我要编辑带有封面图像的商店实体（Image Entity）。 但是我无法捕获和使用已经上传的文件。

我已经尝试了Internet上找到的所有方法，所以不要判断代码的状态：）。

            if(null === $form->get('cover')->get('url')->getData())
            {
                $cover->setUrl(
                    new UploadedFile($this->getParameter('coverImages_directory').'/'.$shop->getCover()->getUrl())
                );

                $shop->setCover($cover);
            }
            else
            {
                // $file stores the uploaded PDF file
                /** @var Symfony\Component\HttpFoundation\File\UploadedFile $file */

                $file = $form->get('cover')->get('url')->getData();
                $realName = $file->getClientOriginalName();
                $cover->setCaption($realName);
                $fileName = $this->generateUniqueFileName().'.'.$file->guessExtension();

                // Move the file to the directory where brochures are stored
                try {
                    $file->move(
                        $this->getParameter('coverImages_directory'),
                        $fileName
                    );
                } catch (FileException $e) {
                    // ... handle exception if something happens during file upload
                }
                $cover->setUrl($fileName);
                $shop->setCover($cover);

            }


            $manager->persist($shop);
            $manager->flush();

            $this->addFlash(
                'success',
                "Les modifications de  <strong>{$shop->getName()}</strong> ont été ajouté avec succes!"
            ); 

            return $this->redirectToRoute('manage_home', [
                'slug' => $shop->getSlug()
            ]);
        }

        return $this->render('/manage/shop/edit.html.twig', [
            'form' => $form->createView(),
            'shop' => $shop,

        ]);
    }

今天，我可以使用_shop_cover_widget及其属性来显示已经上传的文件的名称。

当我检查是否已上传文件时，出现提示“未选择文件”的提示。

谢谢

我希望以下示例可以为您提供帮助，如果您希望在不编辑的情况下上传较旧的图片

/**
 * Displays a form to edit an existing post entity.
 *
 * @Route("/{id}/edit", name="admin_post_edit")
 * @Method({"GET", "POST"})
 */
public function editAction(Request $request, Post $post)
{
    $oldPost = $post->getImage();
    $editForm = $this->createForm('AdminBundle\Form\PostType', $post);
    $editForm->handleRequest($request);

    if ($editForm->isSubmitted() && $editForm->isValid()) {

        if($post->getImage() == null){
            $post->setImage($oldPost);
        }else{

            $file = $post->getImage();
            $fileName = md5(uniqid()).'.'.$file->guessExtension();
            $file->move($this->getParameter('uploads_posts_directory') , $fileName); 
            $post->setImage($fileName);
        }

        $this->getDoctrine()->getManager()->flush();

        return $this->redirectToRoute('admin_post_index');
    }

    return $this->render('post/edit.html.twig', array(
        'post' => $post,
        'edit_form' => $editForm->createView(),
    ));
}
