base_url不能在Codeigniter控制器上工作

Question

Codeigniter无法识别特定控制器上的base_url()，即使它适用于其他控制器并且URL助手已自动加载。这会导致受影响的控制器显示HTML，但不会显示CSS和JS等必要的资源。

假设glitched控制器的视图应在HTML上显示http://localhost/sub/app/assets/css/style.css以正确加载样式表，而是显示http://localhost/sub/app/controller/method/assets/css/style.css。

以下是日志必须说明的内容。

对于那个特殊的故障控制器：

更新：这是毛刺控制器：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Manage extends CI_Controller {

    public function site($section = '')
    {
        if($section == 'general')
            redirect('/manage/site','refresh');
        elseif (!empty($section))
            $this->load->view('manage/site-'.$section);
        else
            $this->load->view('manage/site');
    }

}

/* End of file manage.php */
/* Location: ./app/bulletin/controllers/manage.php */

我会根据您的需要提供更多详细信息。

谢谢！
