Basic Cart Example

[eluser]helmutbjorg[/eluser]
I believe the problem is with the update cart function. We need to get the total items for the cart outside the for loop function as the total_items() is being called each loop. If you set it to a variable first the total will not change during the loop (as you remove products).

Code:

function update_cart()
        {
                $total = $this->cart->total_items();
                for ($i = 1; $i <= $total; $i++)
                {
                        $item = $this->input->post($i);
                        $data = array(
                                'rowid' => $item['rowid'],
                                'qty' => $item['qty']
                        );
                        $this->cart->update($data);
                }
                redirect('shop/show_cart');
        }
