[HELP]URI routing question

[eluser]fanxuan[/eluser]
Glad to be here. I am new to CI.

my routes config is like this :

Code:

$route['user/(:any)/blog/(:num)/'] = "user/blog/$1/$2";

my controller is like this :

Code:

class User extends Controller {
function User()
{
  parent::Controller();
  $this->load->helper('url');
}

function blog()
{
  $user=trim($this->uri->segment(3, 0));
  $id = intval($this->uri->segment(4, 0));
  echo "user";var_dump($user);
  echo "id";var_dump($id);
  //$this->load->view('welcome_message');
}
}

Now I wanna direct the url "http://localhost/blog/index.php/user/fanxuan/blog/2222" to "http://localhost/blog/index.php/user/blog/fanxuan/2222" ,but I failed , it prints 404 Error.

fanxuan is username
2222 is blog id;

Could someone give me some tips how to set the routes to meet my need?

Many many thanks!!

The reason your route failed is because of the trailing slash within the $route key, try:

Code:

$route['user/(:any)/blog/(:num)'] = 'user/blog/$1/$2';

Also, why go through the URI library when you could just pass those values to the method itself?

Code:

function blog($user, $id) {
