Thanks a lot Thomas for this wonderful book though the codes are not working 100%.

I started to copy the part of the code as soon as I am instructed to do so . I mean I am just following your book. So far I done up to chapter 4. I skipped chapter 5 (cart) and started to build the dashboard. At this point I am facing problem with admin login.

Here are my model, view and controller:

Code:

class MAdmins extends Model{

    function __construct(){
        parent::Model();
    }
    
    function verifyUser($u,$pw){
        $this->db->select('id,username');
        $this->db->where('username',db_clean($u,16));
        $this->db->where('password', db_clean(dohash($pw),16));
        $this->db->where('status', 'active');
        $this->db->limit(1);
        $Q = $this->db->get('admins');

        if ($Q->num_rows() > 0){
            $row = $Q->row_array();
            $_SESSION['userid'] = $row['id'];
            $_SESSION['username'] = $row['username'];
        }else{
            $_SESSION['userid'] = 0;
            $this->session->set_flashdata('error', 'Sorry, your username or password is incorrect!');
        }        
    }
}

Code:

function verify(){
    if ($this->input->post('username')){
        $u = $this->input->post('username');
        $pw = $this->input->post('password');
        $this->MAdmins->verifyUser($u,$pw);
        if ($_SESSION['userid'] > 0){
            redirect('admin/dashboard','refresh');
        }
    }
    $data['main'] = 'login';
    $data['title'] = "S &amp; G Suppliers - Admin Login";
    $data['navlist'] = $this->MCats->getCategoriesNav();
    $this->load->vars($data);
    $this->load->view('template', $data);  
  }

Code:

<h2>Please login to Access the Dashboard</h2>
<?php
if ($this->session->flashdata('error')){ 
    //echo "<div class='message'>";
    echo $this->session->flashdata('error');
    //echo "</div>";
}

$udata = array('name'=>'username','id'=>'u','size'=>15);
$pdata = array('name'=>'password','id'=>'p','size'=>15);


echo form_open("sellside/verify");
echo "<p><label for='u'>Username</label><br/>";
echo form_input($udata) . "</p>";
echo "<p><label for='p'>Password</label><br/>";
echo form_password($pdata) . "</p>";
echo form_submit('submit','login');
echo form_close();
?>

Code:

class Dashboard extends Controller {
  function __construct(){
    parent::Controller();
    session_start();
    /*if ($_SESSION['userid'] < 1){
        redirect('sellside/verify','refresh');
    }*/
  }

First of all the error tells me that:
"Fatal error: Call to undefined function db_clean() in C:\wamp\www\s_g_suppliers\system\application\model s\madmins.php on line 11"
"Fatal error: Call to undefined function dohash() in C:\wamp\www\s_g_suppliers\system\application\model s\madmins.php on line 12"

If I remove the functions then I cannot simple log in. I think the problem is because of not using the dohash() the password is not matched with the actual entry. Why it says that the functions are invalid. A I told you i did not copy the entire codes after I downloaded it. I downloaded CI and started to change it according to your book. Is there any place where I should add some librery functions?
