$id not being collected from the uri segment

The issue that I am having is when I go http://domain/admin/editpage/"id" I get 404 not found and I cannot understand why the id is not being passed into the form:

Controller

if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Editsale extends CI_Controller {

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

}

function index() {
    if(!$this->session->userdata('logged_in')) {

    }

        $data['sales_pages'] = $this->sales_model->getSalesPages();
        $data['cms_pages'] = $this->navigation_model->getCMSPages();
        $id = $this->uri->segment(3); 
                    $data['id'] = $id;
        $this->load->library('form_validation');
        $this->form_validation->set_rules('name', 'Name', 'trim|required');

            $this->sales_model->updateSale($data);

            $data['sales'] = $this->sales_model->getSalesPages();   

            redirect('admin/addsale' , $data);

            $this->session->set_flashdata('success', 'Page Saved'); 
        }else{
            $data['content'] = $this->load->view('admin/editsale', NULL, TRUE);
            $this->load->view('template', $data);
        }


}

}

    }

Since you are using the default index method, you need to either include it in your uri:

http://domain/admin/editsale/index/$id

Or set a route:

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

Or use another method:

http://domain/admin/editsale/edit/$id

The index segment is only optional by default if you are not passing any parameters through the uri.

http://domain/admin/editsale

Best of luck.

You need to add

$data['id']=$id;

in your controller to get it worked in the view.
