Question

我有一个带有类用户和文档的应用程序，每个用户都有一个图片配置文件（文档），它工作正常。但现在我遇到了问题，例如我在页面标题上显示的图片：

{% if app.user.picture %}
<img src="{{ asset('uploads/' ~ app.user.picture.Id) }}" alt="" class="img-circle">
{% else %}
<img src="{{ asset('images/default.png') }}" alt="" class="img-circle">
{% endif %}

我得到了html代码：

<img src="/Project/web/uploads/30" alt="" class="img-circle">

此代码在我的本地主机上运行良好，但现在我将其上传到服务器并且图片没有显示。但是，如果我在浏览器上添加扩展程序它会向我显示我想要的内容。这是我的文档实体：

我的Document.orm.yml：

在我的帐户管理员中：

public function editAction(Request $request) {
        $em = $this->getDoctrine()->getManager();
        $entity = $em->getRepository('...Bundle:User')->find($this->getUser()->getId());

        $originalpic = $entity->getPicture();
        $editForm = $this->createEditForm($entity);
        $editForm->handleRequest($request);

        $uploadedFile = $request->files->get('form_user');

        if ($editForm->isValid()) {

            if ($editForm->get('password')->getData()) {
                $factory = $this->get('security.encoder_factory');
                $encoder = $factory->getEncoder($entity);
                $entity->setPassword($encoder->encodePassword($editForm->get('password')->getData(), $entity->getSalt()));
            }

            if ($uploadedFile['picture']) {
                foreach ($uploadedFile as $file) {
                    $pic = new Document();
                    $pic->setName($entity->getUsername());
                    $pic->setFile($file);
                    $pic->setPath();
                    $entity->setPicture($pic);
                    $em->persist($pic);
                    $em->flush();
                    $pic->upload();
                }
            } else {
                $entity->setPicture($originalpic);
            }


            $em->flush();

            $this->container->get("session")->getFlashBag()->add('success', 'Information updated');
            return $this->redirect($this->generateUrl('panel_profile'));
        }

        return $this->render('...Bundle:Panel\Pages\Account:edit.html.twig', array(
                    'entity' => $entity,
                    'edit_form' => $editForm->createView()
        ));
    }

我的问题是，如何更改我的代码以显示带扩展名的图片 ///// 解决方案是在表格和文档实体中添加另一个原始文件：

public function upload() {
        if (null === $this->getFile()) {
            return;
        }
        // check if we have an old image
        if (isset($this->temp)) {
            // delete the old image
            unlink($this->temp);
            // clear the temp image path
            $this->temp = null;
        }

        // you must throw an exception here if the file cannot be moved
        // so that the entity is not persisted to the database
        // which the UploadedFile move() method does

        $this->extension = $this->getFile()->guessExtension();
        $this->getFile()->move(
                $this->getUploadRootDir(), $this->id . '.' . $this->getFile()->guessExtension()
        );

        $this->setFile(null);
    }

Answer 1

 /**
 * @ORM\Column(type="string", length=255, nullable=true)
 */
protected $extension;


//get image extension
  public function getImgExtension(){
    return $this->getFile()->getClientOriginalExtension();

}
 /**
 * Set path
 *
 * @param string $extension
 * @return Document
 */
public function setExtension($extension)
{
    $this->extension = $extension;

    return $this;
}

/**
 * Get path
 *
 * @return string
 */
public function getExtension()
{
    return $this->extension;
}

要获取图片扩展名，请在文档实体中添加此属性和方法。然后从终端运行此命令：

php app/console doctrine:schema:update --force

并在您的twig文件中包含：

<img src="{{asset(document.WebPath)}}.{{document.extension}}" alt="" class="img-circle">

Symfony显示图片扩展
