Adding products to a shoping cart

Guerra · November 3rd, 2008, 07:36 AM

When I try to add a product jumps: Fatal error: Call to a member function updateCart() on a non-object in C:\Program Files\VertrigoServ\www\tutor\system\application\co ntrollers\tutor.php on line 65
Controleer:

Code:

function cart($productid){
      if ($productid > 0){

      $fullproduct = $this->Mproducts_model->getProduct($productid);
65    $this->Morders_model->updateCart($productid,$fullproduct);
      redirect('tutor/product/'.$productid, 'refresh');
      }else{
        $dadta['title'] = "lol | Shopping Cart";
        if(count($_SESSION['cart']) == true){
          $data['main'] = '';
          $nav['navlist'] = $this->Mcats_model->getCategoriesNav();
          $this->load->vars($data);
          $this->load->view('template');
        }else{
          redirect('tutor/index','refresh');
        }
      }
    }

Model:

Code:

<?php
Class Morders_model extends Model{
  function Morders_model(){
    parent::Model();
  }

  function updateCart($productid,$fullproduct){
    //pull in existing cart first!
    $cart = $_SESSION['cart'];//$this->session->userdata('cart');
    $totalprice = 0;
    if (count($fullproduct)){
        if (isset($cart[$productid])){
            $prevct = $cart[$productid]['count'];
            $prevname = $cart[$productid]['name'];
            $prevprice = $cart[$productid]['price'];
            $cart[$productid] = array(
                    'name' => $prevname,
                    'price' => $prevprice,
                    'count' => $prevct + 1
                    );
        }else{
            $cart[$productid] = array(
                    'name' => $fullproduct['name'],
                    'price' => $fullproduct['price'],
                    'count' => 1
                    );
        }

        foreach ($cart as $id => $product){
            $totalprice += $product['price'] * $product['count'];
        }

        $_SESSION['totalprice'] = $totalprice;
        //$this->session->set_userdata('totalprice', $totalprice);
        $_SESSION['cart'] = $cart;
        //$this->session->set_userdata('cart',true);
        $this->session->set_flashdata('conf_msg', "We've added this product to your cart.");
        }
   }
}
?>

Have you declared object for you class

$myobj=new Morders_model()
$myobj.updatecart();

are you doing in above manner. if you are calling updatecart directly then it may not work.

Hi,

Perhaps you haven't loaded the Morders model properly. Did you add it to the autoload.php config (as the book says) or you could use the $this->load function in the constructor of the controller.

I believe the class is MOrders (case sensitive!), not Morders. That's where the problem is.
