我的问题是在上传文件之前检索元数据。
我的配置文件:
vich_uploader:
db_driver: orm
mappings:
media:
uri_prefix: /uploads/
upload_destination: '%kernel.root_dir%/../web/uploads'
inject_on_load: false
delete_on_update: true
delete_on_remove: true
我有一个实体MEDIA:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
**
* @ORM\Entity
* @Vich\Uploadable
*/
class Media
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
*
* @Vich\UploadableField(mapping="media", fileNameProperty="fileName",originalName="originalFileName")
*
* @var File
*/
private $file;
/**
* @ORM\Column(type="string", length=50)
*/
private $fileName;
/**
* @ORM\Column(type="string", length=255, nullable=false)
*/
private $originalFileName;
/**
* @ORM\Column(type="datetime")
*/
private $updatedAt;
/**
* @param File|\Symfony\Component\HttpFoundation\File\UploadedFile $file
*
* @return Media
*/
public function setFile(File $file = null)
{
$this->file = $file;
if ($file) {
$this->updatedAt = new \DateTimeImmutable();
}
return $this;
}
/**
* @return File|null
*/
public function getFile()
{
return $this->file;
}
/**
* @param string $fileName
*
* @return Media
*/
public function setFileName($fileName)
{
$this->fileName = $fileName;
return $this;
}
/**
* @return string|null
*/
public function getFileName()
{
return $this->fileName;
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set updatedAt
*
* @param \DateTime $updatedAt
*
* @return Media
*/
public function setUpdatedAt($updatedAt)
{
$this->updatedAt = $updatedAt;
return $this;
}
/**
* Get updatedAt
*
* @return \DateTime
*/
public function getUpdatedAt()
{
return $this->updatedAt;
}
/**
* Set originalFileName
*
* @param string $originalFileName
*
* @return Media
*/
public function setOriginalFileName($originalFileName)
{
$this->originalFileName = $originalFileName;
return $this;
}
/**
* Get originalFileName
*
* @return string
*/
public function getOriginalFileName()
{
return $this->originalFileName;
}
}
这是我的控制器:
/**
* Creates a new media entity.
*
* @Route("/new", name="media_new")
* @Method({"GET", "POST"})
*
* @param Request $request
*
* @return \Symfony\Component\HttpFoundation\RedirectResponse|\Symfony\Component\HttpFoundation\Response
*/
public function newAction(Request $request)
{
$media = new Media();
$form = $this->createForm(MediaType::class, $media);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($media);
$em->flush();
return $this->redirectToRoute(
'media_list'
);
}
return $this->render(
'media/new.html.twig',
[
'media' => $media,
'form' => $form->createView(),
]
);
}
我的表格:
<?php
/**
* Created by PhpStorm.
* User: rafael
* Date: 4/10/17
* Time: 12:46 PM
*/
namespace AppBundle\Form;
use AppBundle\Entity\Media;
use AppBundle\Entity\MediaDescriptionHelper;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CheckboxType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class MediaType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('file', FileType::class)
->add('save', SubmitType::class, [
'attr' => ['class' => 'btn-primary btn-block']
]);
}
/**
* @param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(['data_class' => Media::class]);
}
}
问题在于这些值的映射:
@Vich \ UploadableField(mapping =&#34; media&#34;,fileNameProperty =&#34; fileName&#34;,originalName =&#34; originalFileName&#34;)
当我提交表单时,这些值为&#39; null&#39; :
执行&INSERT INTO媒体(file_name,original_file_name,updated_at)VALUES(?,?,?)&#39;时发生异常。与params [&#34; get_image_resultat_sans_cache2.php.jpeg&#34;,null,&#34; 2017-04-12 10:11:56&#34;]:
我对所有参数都有这些问题:
(https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md)
UploadableField注释有几个选项。它们如下:
映射:必需,要使用的bundle配置中指定的映射名称; fileNameProperty :必需,包含上传文件名称的属性; size :包含上传文件大小(以字节为单位)的属性; mimeType :包含上传文件的mime类型的属性; originalName :包含上传文件的原始名称的属性。
我不知道自己做错了什么......
提交表单后,这是我的媒体(实体):
媒体{#403▼ -id:null -file:UploadedFile {#15▼ -test:false -originalName:&#34; get_image_resultat_sans_cache2.php.jpeg&#34; -mimeType:&#34; image / jpeg&#34; -size:203751 -error:0 路径:&#34; / tmp&#34; filename:&#34; php9xsTdF&#34; basename:&#34; php9xsTdF&#34; 路径名:&#34; / tmp / php9xsTdF&#34; 扩展名:&#34;&#34; realPath:&#34; / tmp / php9xsTdF&#34; 时间:2017-04-12 10:11:56 mTime:2017-04-12 10:11:56 cTime:2017-04-12 10:11:56 inode:6160452 大小:203751 烫发:0100600 拥有者:1000 组:1000 输入:&#34; file&#34; 可写的:真的 可读:真实 可执行文件:false file:true 迪尔:假 链接:false } -fileName:null -originalFileName:null
在上传文件之前设置元数据似乎是个问题...
提前多多感谢...
答案 0 :(得分:2)
您使用的是哪个版本的VichUploaderBundle?
注释的文档是指dev-master,而稳定文档(1.5.3)不支持开箱即用的元数据注释。
您可以看到1.5.3版本中的Vich \ UploaderBundle \ Mapping \ Annotation \ UploadableField.php仅处理注释'mapping'和'fileNameProperty'。
在dev-master中,它处理那些和大小,mimeType和originalName。
与Vich \ UploaderBundle \ Metadata \ Driver \ AnnotationDriver相同
如果要在1.5.3版本中实现此目的,则需要创建eventListener。
以下是Vich触发的事件:https://github.com/dustin10/VichUploaderBundle/blob/1.5.3/Event/Events.php
