User edit page not working - codeigniter

Question

When i click on my user edit button <?php echo anchor('users/edit/'. $user->user_id, '<div class="btn btn-primary"><i class="fa fa-edit"></i> Edit</div>');?>
It sends me to http://localhost/codeigniter/codeigniter-blog/admin/users/edit/1 but shows error 404 Page Not Found. '1' example is the user_id
But edit function exists. How can I make my edit function on my users controller work with the user id. So if i click on a certain user it will only update that id row information.
Model
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Model_user extends CI_Model {
protected $id;
function getAll() {
$query = $this->db->get('user');
if ($query->num_rows() > 0) {
return $query->result();
return $query->row('user_id');
return true;
} else {
return false;
}
}
public function editUser() {
}
public function getID($user_id) {
$user_query = $this->db->get('user');
if ($user_query->num_rows() == 1) {
return $user_query->row('user_id', $user_id);
return true;
} else {
return false;
}
}
}
Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Users extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('user');
if ($this->session->userdata('isLogged') == TRUE) {
return true;
} else {
redirect('/');
}
}
public function index() {
$this->getList();
}
public function edit() {
$this->load->library('form_validation');
$this->load->model('users/model_user');
$this->form_validation->set_rules('name', 'Name');
$this->form_validation->set_rules('username', 'Username');
if ($this->form_validation->run() == TRUE) {
redirect('users');
} else {
$this->getForm();
}
}
function getForm() {
$data['title'] = "Users";
$data['base'] = config_item('HTTP_SERVER');
$data['isLogged'] = $this->user->isLogged();
$this->load->model('users/model_user');
$data['users'] = $this->model_user->getAll();
$data['header'] = $this->load->view('template/common/header', $data, TRUE);
$data['footer'] = $this->load->view('template/common/footer', NULL, TRUE);
return $this->load->view('template/users/users_form', $data);
}
function getList() {
$data['title'] = "Users";
$data['base'] = config_item('HTTP_SERVER');
$data['isLogged'] = $this->user->isLogged();
$this->load->model('users/model_user');
$data['text_enabled'] = "Enabled";
$data['text_disabled'] = "Disabled";
$data['users'] = $this->model_user->getAll();
$data['header'] = $this->load->view('template/common/header', $data, TRUE);
$data['footer'] = $this->load->view('template/common/footer', NULL, TRUE);
return $this->load->view('template/users/users_list', $data);
}
}

Answer 1

May be you miss to use index.php in url
(OR)
Use below code base_url('');
<?php
$url=base_url('users/edit/'. $user->user_id);
echo anchor($url, '<div class="btn btn-primary"><i class="fa fa-edit"></i> Edit</div>');?>

I can view page now to do with routes $route['users/edit/(:num)'] = "users/users/edit/$1";
