Codeigniter index page

Question

I want to create a page, which I will be able to browse like this: /page/5.

I have created a page.php controller and I can view this page, here is its content:

class Page extends CI_Controller {

public function __construct()
{
    parent::__construct();
}

public function index()
{
    $this->load->view('template/header');

    $id = $this->uri->segment(2);
    $this->load->view('template/middle', array('id' => $id));
    $this->load->view('template/footer');
}

}

The problem is that I cant reach the page number from the uri.

To be clear:

This is reachable: index.php/page.

But at this url, I'm getting the 404: index.php/page/5

I know I can make another controller function to view the page like this /index.php/page/id/5, but I want it be be accessable via the index function.

Is that possible?

CodeIgniter doesn't know whether you're looking for 5() or index(5)

To fix this, Try setting up a custom route in config/routes.php:

$route['page/(:num)'] = 'page/index/$1';

Also, In your index function:

public function index($id)
{
    $this->load->view('template/header');
    $this->load->view('template/middle', array('id' => $id));
    $this->load->view('template/footer');
}

Nice, thank you :-). What is the difference of using public function index(*$id*) and $id = $this->uri->segment(2);?

No problem, Well you could still use segments, I just think that arguments are fancier :P

if you do public function index($id), you HAVE to pass in an id like this page/index/1. if you try to access page/index, it will not work.

@Catfish He can still make it optional: index($id=false)

I know, but he asked what the difference was between index($id) and the $this->uri->segment() so i was just trying to clarify.
