而一个档案更新形式，这样的：

public function editAction($id, Request $request) 
    { 
     $em = $this->getDoctrine()->getManager(); 
     $profile = $em->getRepository('KrownDashboardBundle:Profile')->find($id); 
     if (!$profile) { 
     throw $this->createNotFoundException(
       'No news found for id ' . $id 
     ); 
     } 

     $form = $this->createFormBuilder($profile) 
      ->add('title', 'text') 
      ->add('breve_description', TextareaType::class, array(
      'attr' => array('class' => 'tinymce'), 
      )) 
      ->add('fields_of_law', 'choice', array(
       'choices' => array(
        'Droit du travail' => "Droit du travail", 
        'Droit de la famille' => "Droit de la famille", 
        'Contrats commerciaux' => "Contrats commerciaux", 
      ), 
       'choices_as_values' => true, 
       'multiple' => true, 
     )) 
      ->add('imageFile', FileType::class, array(
       'label' => 'Photo', 
       'data' => $profile->getImageFile(), 
       'required'  => false, 
      ) 
      ) 
      ->add('registre_ou_bareau') 
      ->add('canton_actif') 
      ->add('annee_obtention_brevet') 
      ->add('titre_supplementaire') 
      ->add('years_of_experience') 
      ->add('langues_de_travail') 
      ->add('email_contact') 
      ->add('numero_telephone') 
      ->add('avocat') 
      ->getForm(); 

     $form->handleRequest($request); 

     if ($form->isValid()) { 
      $em->flush(); 
      return new Response('Profile updated successfully'); 
     } 

     $build['form'] = $form->createView(); 

     return $this->render('KrownDashboardBundle:Profile:profiles_edit_add.html.twig', $build); 
    } 

在这种形式下，我可以更新和检索任何除了与FileType field完全一致。

当我提交表单，文件$镜像文件正确上传，文件名$ imageName存储在数据库中。问题是我无法附加已加载到表单上的文件。

我可以得到$简介 - > getImageName（）存储在数据库中的文件名，但是当我做$简介 - > getImageFile（），我得到一个空值？

我错过了什么吗？

EDIT

我也试图手动加载文件与这样的文件名。

$profile->setImageFile(
    new File(__DIR__.'/../../../../web/images/products/'.$profile->getImageName()) 
); 

现在，当我做$简介 - > getImageFile（）我可以看到该文件，但它没有连接到表格。

Answer 1

为了安全起见，您不能将文件附加到文件输入，这是不可能的。但是，相反，您可以使用一些jQuery库来显示/上传文件（可能是bluimp），或者只显示带有文件路径的图像标记，允许将用户更改为文件。
