Question

我正在尝试将JqueryFileUpload上传的文件保存在Sonata Media中，但它无效。我使用OneUpUploaderBundle将JQueryFileUpload与Symfony2集成

我已尝试使用postUploadEvent和preUploadEvent

使用jQuery脚本中的data.files。

如果有人知道如何通过Symfony或JQuery获取内容的文件对象将是一个很大的帮助。

public function onUpload(PreUploadEvent $event) {

    $request = $event->getRequest();

    $files = $request->files->get('uploadFiles');

    foreach ($request->files->get('uploadFiles') as $fotoTemporaria) {

    $foto = new Media();

    $foto->setProviderName('sonata.media.provider.image');
    $foto->setContext('default');
    $foto->setBinaryContent($fotoTemporaria);
    $foto->setEnabled(true);

    $mediaManager->persist($foto);
    $mediaManager->flush();

    }

    $response = $event->getResponse();

    $response['uploadedFiles'] = $files;

    $response['success'] = true;
    return $response;
}

services.yml文件

media_upload_listener:
     class: AppBundle\ClassServices\UploadListener
     arguments: [@doctrine.orm.entity_manager]
     tags:
         - { name: kernel.event_listener, event: oneup_uploader.post_persist, method: onUpload }

和jQuery文件

$(document).ready(function ()
    {
        $('#fileupload').fileupload({
            add: function (e, data) {
                if (data.files && data.files[0]) {
                    var reader = new FileReader();
                    reader.onload = function (e) {
                        $('#uploaded').append("<div id='imageNumber' class='imageContainer'><img class='imagePreview' src='" + e.target.result + "'> \n\
                <input type='file' name='realMedia[]' style='display:none' value='" + e.target.result + "'></div>");
                    }
                    data.result = data.files[0];
                    reader.readAsDataURL(data.files[0]);
                    data.submit();
                }
            },
            progress: function (e, data) {
                var progress = parseInt(data.loaded / data.total * 100, 10);
                $('#progress .bar').css(
                        'width',
                        progress + '%'
                        );
            },
            done: function (e, data) {
                var out ='';
                var obj = data;
                for (var i in obj) {
                    out += i + ": " + obj[i] + "\n";
                }

                this attribute is empty
                alert(data.files);

              }
        });
    });

我发现了正在发生的事情。这是因为我在构造中使用的是ObjectManager而不是EntityManager。

类UploadListener {

protected $em;

public function __construct(EntityManager $em) {
    $this->em = $em;
}

public function getEm() {
    return $this->em;
}

public function onUpload(PostPersistEvent $event) {

    $file = $event->getFile();

    $entityManager = $this->getEm();

    $foto = new Media();

    $foto->setProviderName('sonata.media.provider.image');
    $foto->setContext('default');
    $foto->setBinaryContent($file);
    $foto->setUsuario($event->getRequest()->get('user'));
    $foto->setEnabled(true);

    $entityManager->persist($foto);
    $entityManager->flush();

    $response = $event->getResponse();

    $response['success'] = true;

    return $response;
}

}
