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
$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'] = '';





控制器是这样的
PHP

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);
$this->load->view('content/view', $data);
$this->load->view('templates/footer');
}

public function add()
{
$this->load->helper('form');
$this->load->library('form_validation');

$data['title'] = 'Add a content item';

$this->form_validation->set_rules('title', 'Title', 'required');
$this->form_validation->set_rules('text', 'text', 'required');

if ($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header', $data);
$this->load->view('content/add');
