上传多个文件时上传进度

Question

我想上传多个文件（超过1000个文件，总数超过2GB）。在php中，我使用函数

if (move_uploaded_file($_FILES['files']['tmp_name'][$i], $original_file))
                    {
                        $stamp = '../contents/wm_watermark.png';
                        $this->create_watermark_photo($original_file, $stamp, $view_file, $ext);
                        $this->makeThumbnail($view_file, $thumb_file, $this->max_width_thumb, $this->max_width_thumb);

                        //insert photo info to DB
                        $this->Photo->create();
                        $this->Photo->save(
                            array(
                                'Photo' =>  array(
                                    'folder_id' =>  $data_from_preparing_fileInfoList[$i]['sub'],
                                    'name'      =>  $filename
                                )
                            )
                        );

                        $status = '1';
                        $count++;
                    }

我发现，当使用move_upload_file时，它现在没有上传。它只保持等待堆栈。当此函数完成运行时，它将文件移动到服务器。所以，当我使用上传过程，它获得100％，这个ajax网址仍然运行。

$("#image_upload_form").ajaxSubmit({
                    //url: '/admin/photoGroup/ajax_upload_photo', //photo upload process bar
                    type: 'POST',
                    dataType: 'json',
                    data: { data_from_preparing: data_from_preparing},
                    beforeSend: function() {
                        //dialog 1
                        $("#upload-photo-process .progress-bar").css('width', '0');
                        $('#upload-photo-process').modal('show');

                    },
                    /* progress bar call back*/
                    uploadProgress: function(event, position, total, percentComplete) {
                        console.log('percentComplete' + percentComplete);
                        console.log('position: ' + position);
                        console.log('total' + total);
                        var mbPosition = position / 1024 / 1024;
                        var mbTotal = total / 1024 / 1024;
                        var txtProcess = percentComplete + '% | ' + mbPosition + 'Mb/' + mbTotal + 'Mb';
                        var pVel = percentComplete + '%';
                        $("#upload-photo-process .process-status").html(txtProcess);

                        $("#upload-photo-process .progress-bar").css('width', pVel);

                    },

                    /* complete call back */
                    complete: function(xhr) {
                        if (xhr.statusText == "OK") {
                            $('#upload-photo-process').modal('hide');
                            $('#upload-done').modal('show');
                        }

                    }
                    /*success: function(data_from_photo_upload) {

                    }*/

                });

现在，我想在上传进度增加100％时，将所有文件上传到服务器。我怎么能这样？谢谢高级。
