我正在尝试通过http://codeigniter.com/forums/viewthread/109584/P20上的wiredesignz 设置小部件插件，但我不断收到错误消息。我很确定我已经按照线程中的指示进行了所有设置，但是当我<?php widget::run("test"); ?>在我的视图中尝试时，我得到了以下信息：
class Test extends Widget { function run() { echo "test"; } }
Fatal error: Class 'Test' not found in C:\xampp\htdocs\test\application\helpers\widget_helper.php on line 52
我能想到的唯一与我的安装不同的是，我使用的是 Phil Sturgeon 的模板库。
以下是我如何构建所有内容：
/application/helpers/widget_helper.php
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

/application/widgets/test.php
class Test extends Widget {
function run() {
echo "test";
}
}
/application/views/layouts/public.php
<?php widget::run("test"); ?>
知道如何让这个工作吗？这只是过时了吗？
我一直在寻找更好的解决方案来做小部件，但我似乎找不到任何东西。我只需要能够逐页控制站点侧边栏上显示的内容。有没有替代方法？
编辑：错误来自评论中的小部件库
