如何在我的更新表单上检索存储在数据库中的图像?

我已经设置了这样的Profile实体:

还有这样的个人资料更新表格:

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);
   }

在这个表单上,我可以完美地更新和检索任何字段,除了FileType 字段

当我提交表单时,文件$imageFile已正确上传,文件名$imageName存储在数据库中。问题是我无法在加载时附加已上传到表单的文件。

我可以使用$profile->getImageName()获取存储在数据库中的文件名,但是当我执行$profile->getImageFile()时,我得到一个空值?

我错过了什么吗?

编辑

我还尝试手动加载具有类似文件名的文件。

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

现在,当我执行 $profile->getImageFile() 时,我可以看到该文件,但它没有附加到表单中。

您应该在提交表单之前编写此代码

$image = $profile->getImageFile();
if ($image !== null) {
    $profile->setImageFile(new File($this->getParameter('your image dir name') . '/' . $image));
}

$file = $project->getProfilePic();
$project->setProfilePic($file);

如果您想更新或保留旧文件,请在提交后尝试粘贴此代码

// add the new one
if ($profile->getImageFile() !== null) {

    $newImage = $profile->getImageFile();
    $newImageName = md5(uniqid()) . '.' . $file->guessExtension();
    $newImage->move($this->getParameter('your image dir'), $newImageName);
    $project->setImageFile($newImageName);
} else {
    //Restore old file name
    $profile->setProfilePic($image);
}

您不能将文件附加到文件输入,出于安全目的,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签,允许更改用户文件。
