Ну что нашел ответ как?

я нашел!

В общем делаешь такое

<div id="uploader">
     <div class="row fileupload-buttonbar">
            <div class="col-lg-7">
                <!-- The fileinput-button span is used to style the file input field as button -->
                <span class="btn btn-success fileinput-button">
                	<i class="icon-plus icon-white"></i>
                    <span>Загрузка фотографий</span>
                    <input type="file" name="files[]" multiple>
                </span>
                <button type="submit" class="btn btn-primary start">
                    <i class="glyphicon glyphicon-upload"></i>
                    <span>Start upload</span>
                </button>
                <button type="reset" class="btn btn-warning cancel">
                    <i class="glyphicon glyphicon-ban-circle"></i>
                    <span>Cancel upload</span>
                </button>
                <button type="button" class="btn btn-danger delete">
                    <i class="glyphicon glyphicon-trash"></i>
                    <span>Delete</span>
                </button>
                <input type="checkbox" class="toggle">
                <!-- The global file processing state -->
                <span class="fileupload-process"></span>
            </div>
            <!-- The global progress state -->
            <div class="col-lg-5 fileupload-progress fade">
                <!-- The global progress bar -->
                <div class="progress progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100">
                    <div class="progress-bar progress-bar-success" style="width:0%;"></div>
                </div>
                <!-- The extended global progress state -->
                <div class="progress-extended">&nbsp;</div>
            </div>
        </div>
        <!-- The table listing the files available for upload/download -->
        <table role="presentation" class="table"><tbody class="files"></tbody></table>
     </div>
    </div>

И инициализируешь в js

$('#mainWindow').fileupload({

}).on('fileuploadsubmit', function (e, data) {
data.formData = {твоя переменная: значение}

Затем заходишь в папку server/php/index.php (я использовал последней версии плагин, так что содержимое может отличаться. Рекомендую установить плагин версии 9.5.2)
Вставляешь вместо всего кода, который там есть этот

$options = array(
    'delete_type' => 'POST',
    'db_host' => 'localhost',
    'db_user' => 'root',
    'db_pass' => '',
    'db_name' => 'mycbc',
    'db_table' => 'card_photos'
);

error_reporting(E_ALL | E_STRICT);
require('UploadHandler.php');

class CustomUploadHandler extends UploadHandler {

    protected function initialize() {
    	$this->db = new mysqli(
    		$this->options['db_host'],
    		$this->options['db_user'],
    		$this->options['db_pass'],
    		$this->options['db_name']
    	);
        parent::initialize();
        $this->db->close();
    }

    protected function handle_form_data($file, $index) {
	$file->твоя переменная = @$_REQUEST['твоя переменная'][$index];
    }

    protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
            $index = null, $content_range = null) {

        	$uploaded_file, $name, $size, $type, $error, $index, $content_range
        );
        if (empty($file->error)) {

	        $query->execute();
	        $file->id = $this->db->insert_id;
        }
        return $file;
    }

    protected function set_additional_file_properties($file) {
        parent::set_additional_file_properties($file);
        if ($_SERVER['REQUEST_METHOD'] === 'GET') {
        	$sql = 'SELECT `id`, `type`, `title`, `description` FROM `'
        		.$this->options['db_table'].'` WHERE `name`=?';
        	$query = $this->db->prepare($sql);
 	        $query->bind_param('s', $file->name);
	        $query->execute();
	        $query->bind_result(

    		}
        }
    }

    public function delete($print_response = true) {
        $response = parent::delete(false);
        foreach ($response as $name => $deleted) {
        	if ($deleted) {
	        	$sql = 'DELETE FROM `'
	        		.$this->options['db_table'].'` WHERE `name`=?';

	 	        $query->bind_param('s', $name);

        	}
        } 
        return $this->generate_response($response, $print_response);
    }

}

$upload_handler = new CustomUploadHandler($options);

В общем для тебя даже доработал сохранение всех передаваемых значений в MySQL БД )))))))).
Надеюсь разберешься
