codeigniter我的删除不知道是不能传参还是路由问题

路由是这样的
PHP复制代码
<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$route['default_controller'] = 'pages/view';
 
$route['content/(:any)'] = 'content/view/$1';
$route['content'] = 'content';
$route['content/del/(:any)'] = 'content/del/$1';
$route['content/add'] = 'content/add';
$route['(:any)'] = 'pages/view/$1';
 
$route['404_override'] = '';
复制代码




控制器是这样的
PHP复制代码
<?phpclass Content extends CI_Controller {
 
        public function __construct()
        {
                parent::__construct();
                $this->load->model('content_model');
        }
        
        public function index()
        {
                $data['title'] = 'Content archive';
                $data['content'] = $this->content_model->get_content();
                
                $this->load->view('templates/header', $data);
                $this->load->view('content/index', $data);
                $this->load->view('templates/footer');
        }
        
        public function view($slug)
        {
                $data['content_item'] = $this->content_model->get_content($slug);
                
                if (empty($data['content_item']))
                {
                        show_404();
                }
                
                $data['title'] = $data['content_item']['title'];
                
                $this->load->view('templates/header', $data);
             &nbs
