在发布此问题之前，我已经尝试了 4 次，但没有运气。
我仔细阅读了文档，在安装 VichUploaderBundle 后，我创建了上传歌曲的代码，如下所示：
实体/模型
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
/**
* @ORM\Entity
* @Vich\Uploadable
*/
class Song
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
// ..... other fields
/**
* NOTE: This is not a mapped field of entity metadata, just a simple property.
*
* @Vich\UploadableField(mapping="song_track", fileNameProperty="trackName")
*
* @var File
*/
private $trackFile;
/**
* @ORM\Column(type="string", length=255)
*
* @var string
*/
private $trackName;
/**
* @ORM\Column(type="datetime")
*
* @var \DateTime
*/
private $updatedAt;
/**
* If manually uploading a file (i.e. not using Symfony Form) ensure an instance
* of 'UploadedFile' is injected into this setter to trigger the update. If this
* bundle's configuration parameter 'inject_on_load' is set to 'true' this setter
* must be able to accept an instance of 'File' as the bundle will inject one here
* during Doctrine hydration.
*
* @param File|\Symfony\Component\HttpFoundation\File\UploadedFile $trackName
*/
public function setTrackFile(File $trackName = null)
{
$this->$trackName = $trackName;
if ($trackName) {
var_dump($trackName);
// It is required that at least one field changes if you are using doctrine
// otherwise the event listeners won't be called and the file is lost
$this->updatedAt = new \DateTime('now');
}
}
/**
* @return File
*/
public function getTrackFile()
{
return $this->trackFile;
}
/**
* @param string $imageName
*/
public function setTrackName($trackName)
{
$this->trackName = $trackName;
}
/**
* @return string
*/
public function getTrackName()
{
return $this->trackName;
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set updatedAt
*
* @param \DateTime $updatedAt
*
* @return Track
*/
public function setUpdatedAt($updatedAt)
{
$this->updatedAt = $updatedAt;
return $this;
}
/**
* Get updatedAt
*
* @return \DateTime
*/
public function getUpdatedAt()
{
return $this->updatedAt;
}
}
控制器
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use AppBundle\Entity\Song;
class UploadTrackController extends Controller
{
/**
* @Route("/uploadtrack", name="uploadtrackform")
*/
public function indexAction(Request $request)
{
$track = new Song();
$form = $this->createFormBuilder($track)
->add('trackFile', 'file')
->add('save', 'submit', array('label' => 'Upload File'))
->getForm();
$form->handleRequest($request);
return $this->render('default/uploadtrack.html.twig',
array(
'form' => $form->createView(),
)
);
}
}
看法
<body>
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
</body>
我可以看到表单，上传文件并正确触发控制器。我没有收到任何错误，但既没有将文件复制到文件夹中，也没有将数据保存到数据库中。
您可以在我的实体中看到我有一个 var_dump 它实际上包含一个错误属性。提交表单后，这就是我从该 var_dump 中得到的：
对象（Symfony\Component\HttpFoundation\File\UploadedFile）#13 (7) { ["test":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=> bool(false) ["originalName":"Symfony \Component\HttpFoundation\File\UploadedFile":private]=> string(24) "file.pdf" ["mimeType":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=> string(15) "application /pdf" ["size":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=> int(186992) ["error":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=> int (0) ["路径名":"SplFileInfo":private]=> 字符串(66)"/private/var/folders/1g/4t5n9rhj0_s_9tnstpjj6w_w5wl8pn/T/phpptwjZH" ["文件名":"SplFileInfo":private]=> 字符串(9) "phpptwjZH" }
在我看来，该文件暂时存储在某处，但从未复制到文件夹中，因此学说不会将任何数据保存到数据库中。
对不起，如果我没有找到更简洁的方法，但这个问题主要是针对那些有 Symfony 和 VichUploaderBundle 经验的人。
先感谢您
以防万一您想知道捆绑包的配置是什么，我们开始吧：
#VichUpload config
vich_uploader:
db_driver: orm # or mongodb or propel or phpcr
mappings:
song_track:
uri_prefix: /upload/tracks
upload_destination: %kernel.root_dir%/../web/upload/tracks
更新
像下面建议的 K-Phoen 一样在 Song 实体中修改了 setter，仍然是同样的问题：/ PS：我正在使用 Symfony 内部服务器 php app/console server:run 运行项目
public function setTrackFile(File $trackFile = null)
{
$this->trackFile = $trackFile;
if($trackFile){
var_dump($trackFile);
// It is required that at least one field changes if you are using doctrine
// otherwise the event listeners won't be called and the file is lost
$this->updatedAt = new \DateTime('now');
}
}
更新 2
将它添加到我的控制器使整个工作正常，文件被复制，数据库被写入......
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($track);
$em->flush();
}
...顺便说一句，我在阅读 VichUploaderBundle 文档后感到困惑，因为我了解到这种持久化是自动调用的，无需指定任何其他内容，然后 $form->handleRequest($request); 在控制器中。
