在发布此问题之前，我一直在尝试4次而没有运气 .
我仔细阅读了文档，安装完VichUploaderBundle之后，我创建了我的代码来上传一首歌，如下所示：
Entity/Model
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;
}
}
Controller
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(),
)
);
}
}
View
<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，但文件没有复制到文件夹中或数据持久存储到数据库 .
您可以在我的实体中看到我有一个实际上包含错误属性的var_dump . 提交表单后，这是我从var_dump获得的：
object（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）[“pathName”：“SplFileInfo”：private] => string（66）“/ private / var / folders / 1g / 4t5n9rhj0_s_9tnstpjj6w_w5wl8pn / T / phpptwjZH”[“fileName”：“SplFileInfo”：private] => string（9）“phpptwjZH”}
在我看来，文件暂时存储在某个地方但从未复制到文件夹中，因此没有数据通过doctrine持久保存到db .
很抱歉，如果我没有找到更简洁的方法，但这个问题主要针对那些有Symfony和VichUploaderBundle经验的人 .
先感谢您
万一你想知道捆绑包的配置是什么，我们在这里：
#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
UPDATE
宋实体中的修改后的setter就像下面提到的K-Phoen一样，还是同样的问题：/ PS：我正在使用Symfony内部服务器php app / console服务器运行项目：运行
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
$this->updatedAt = new \DateTime('now');
}
}
UPDATE 2
将此添加到我的控制器使整个工作正常，文件被复制，数据库被写入......
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($track);
$em->flush();
}
...顺便说一句，我在这一点上感到困惑，因为我读了VichUploaderBundle文档，我知道这个持久化是自动调用的，无需另外指定任何其他的$ form-> handleRequest（$ request）;在控制器中 .

setTrackFile(…)setter不正确：它应该更新trackFile属性而不是trackName.
