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="media", fileNameProperty="fileName",originalName="originalFileName")
当我提交表单时，这些值为 'null' ：
使用参数 ["get_image_resultat_sans_cache2.php.jpeg", null, "2017-04-12 10:11:56" 执行 'INSERT INTO media (file_name, original_file_name, updated_at) VALUES (?, ?, ?)' 时发生异常]：
我对所有参数都有这些问题：
（https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md）
UploadableField 注解有几个选项。它们如下：
mapping：必需，在捆绑配置中指定要使用的映射名称； fileNameProperty：必需，将包含上传文件名称的属性； size：将包含上传文件的大小（以字节为单位）的属性； mimeType：将包含上传文件的 mime 类型的属性； originalName：将包含上传文件的原始名称的属性。
我看不出我做错了什么...
提交表单后，这是我的媒体（实体）：
媒体 {#403 ▼ -id: null -file: UploadedFile {#15 ▼ -test: false -originalName: "get_image_resultat_sans_cache2.php.jpeg" -mimeType: "image/jpeg" -size: 203751 -error: 0 path: " /tmp" 文件名："php9xsTdF" 基名："php9xsTdF" 路径名："/tmp/php9xsTdF" 扩展名："" realPath:"/tmp/php9xsTdF" aTime: 2017-04-12 10:11:56 mTime: 2017-04 -12 10:11:56 cTime: 2017-04-12 10:11:56 inode: 6160452 size: 203751 perms: 0100600 owner: 1000 group: 1000 type: "file" writable: true 可读: true executable: false file: true dir: false link: false } -fileName: null -originalFileName: null
在上传文件之前设置元数据似乎是一个问题......
非常感谢提前...
