Uploadify 和 Codeigniter 框架

Question

我在使用 uploadify (http://www.uploadify.com/) 和 Codeigniter 框架 (http://codeigniter.com) 时遇到问题。

请检查控制器部分：

function uploadFile()
    {
    require_once('class.upload.php');
if (!empty($_FILES)) {
         $uc = $this->session->userdata('username');
         //$_REQUEST['folder'] = "/pro/user/Dileepmt/pages/".$_REQUEST['folder']."/images/background";
         $_REQUEST['folder'] = $uc."/pro/user/".$uc."/pages".$_REQUEST['folder']."/images/background";
        $targetPath = $_SERVER['DOCUMENT_ROOT'] .$_REQUEST['folder']. '/';
        $pic_temp = random_string('alnum',10);

        $handle = new Upload($_FILES['Filedata']);
            if ($handle->uploaded) {
                $handle->file_src_name_body      = $pic_temp; // hard name
                $handle->file_overwrite          = true;
                $handle->file_auto_rename        = false;
                $handle->image_resize            = true;
                $handle->image_ratio_y           = true;
                $handle->image_x                 = ($handle->image_src_x < 400)?$handle->image_src_x:400;
                $handle->file_max_size           = '819200'; // max size
                $handle->Process($targetPath);
                $handle->clean(); 
                if ($handle->processed)
                    $json = array("result"      => 1, 
                                  "file"        => $_REQUEST['folder'].'/'.$handle->file_dst_name.'?'.time(),
                                  "imagewidth"  => $handle->image_dst_x,
                                  "imageheight" => $handle->image_dst_y
                                 );
                else
                    $json = array("result" => 0);

                $encoded = json_encode($json);
                echo $encoded;
                unset($encoded);    
            } 
            else { 
                $json = array("result" => 0);
                $encoded = json_encode($json);
                echo $encoded;
                unset($encoded);
            }
}


    }

Uploadify 有很多问题，但在这里我无法使用 Codeigniter 会话库检索会话数据。

$uc = $this->session->userdata('username');

 $_REQUEST['folder'] = $uc."/pro/user/pages".$_REQUEST['folder']."/images/background";

假设 username = >'myuser' 和 'folder' = >'myfolder'

所以$_REQUEST['folder'] 将是myuser/pro/user/pages/myfolder/images/background

但结果是/pro/user/pages/myfolder/images/background

我检查了 Codeigniter 会话没有问题，我可以使用会话库设置或检索数据。

Uploadify 使用 Flash。 Flash 与您的浏览器分开，不会发送任何会话 ID 或 cookie。您可以使用 uploadifies 'scriptData' 属性来发送会话 ID 或其他内容。我在 html 表单中生成一个上传 id 并将其发送给 uploadify。提交公式后，我从上传目录中收集文件并将它们连接到会话。
