Question

我的多文件上传存在问题。我使用了一个包LcnFileUploaderBundle。

当我点击save我的文件时，请不要保存在正确的文件夹中。我使用函数syncFilesFromTemp。当我将功能更改为syncFilesToTemp时，一切正常，但将我的文件保存在临时文件夹中。我的控制器和twig文件与链接中的文件相同。

我的控制员：

/**

 *
 * In a real world scenario you might want to check edit permissions
 *
 * @param Request $request
 * @param $entityId
 * @return \Symfony\Component\HttpFoundation\RedirectResponse|\Symfony\Component\HttpFoundation\Response
 */
public function editAction(Request $request, $entityId)
{
    $editId = intval($entityId);
    if ($editId < 1000000000) {
        throw new \Exception('invalid editId');
    }

    $fileUploader = $this->container->get('lcn.file_uploader');
   // $fileUploader1 = $this->container->get('lcn.file_manager');

    $uploadFolderName = $this->getUploadFolderName($editId);

    $form = $this->createFormBuilder()
        ->setAction($this->generateUrl('lcn_file_uploader_demo_edit', array('entityId'  => $entityId)))
        ->setMethod('POST')
        ->getForm();

    if ($request->getMethod() == 'POST') {
        $form->submit($request);

        if ($form->isValid()) {

            $fileUploader->syncFilesFromTemp($uploadFolderName);

            return $this->redirect($this->generateUrl('addItemGallery', array('entityId'  => $entityId)));
        }
    } else {
        $fileUploader->syncFilesToTemp($uploadFolderName);
    }

    return $this->render('PortfolioAdminBundle:Gallery:edit.html.twig', array(
        'entityId' => $entityId,

}
