路由是这样的
PHP复制代码
$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

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');
$this->load->view('templates/footer');

}
else
{
$this->content_model->set_content();
$this->load->view('templates/header', $data);
$this->load->view('content/add_success');
$this->load->view('templates/footer');
}
}

public function del($slug)
{
$this->content_model->del_content($slug);
}

}
复制代码


数据模型是这样的
PHP复制代码

public function __construct()
{
$this->load->database();
}

public function get_content($slug = FALSE)
{
if ($slug === FALSE)
{
$query = $this->db->get('content');
return $query->result_array();
}

$query = $this->db->get_where('content', array('id' => $slug));
return $query->row_array();
}

public function set_content()
{
$this->load->helper('url');

$slug = url_title($this->input->post('title'), 'dash', TRUE);

$data = array(
'title' => $this->input->post('title'),
'slug' => $slug,
'text' => $this->input->post('text')
);

return $this->db->insert('content', $data);
}

public function del_content($slug)
{
$this->db->where('id',$slug);
$this->db->delete('content');
}
}

我http://localhost/ci//index.php/content/del/1
后就是404 Page Not Found
不知道是不能传参还是路由问题

回复讨论(解决方案)

如果象 http://localhost/ci/index.php/content/del/1 这样的 url 会找不到文件的话
就表示你的 web 服务器不支持 PATH_INFO

如果web 服务器不支持 PATH_INFO，
为什么
http://localhost/ci//index.php/content/1
确能显示文章

$route['content/(:any)'] = 'content/view/$1';

写路由的一个原则：会被包含的规则要写在包含他的规则上面，否则就应用不到了。

5楼正解，
$route['content/del/(:any)'] = 'content/del/$1';一定要放在
$route['content/(:any)'] = 'content/view/$1';的前面，否则会背后截获
