Code:

<?php
class cart extends Controller{
    //
    function cart(){
        parent::Controller();
        
        $this->load->library('cart');
    }
    //
    function index(){
        
        $this->view_cart();
    }
    
    function add(){
        $pid = $this->input->post('product_id');
        //
        $q = $this->db->get_where('product',array('product_id'=>$pid),1);
        if($q->num_rows() > 0){
            $item = $q->row();
            
            //
            $data = array('id' => $item->product_id,
                          'qty' => 1,
                          'price' => $item->product_price,
                          'name' => $item->product_sku."".$item->product_name
            );
            
            $this->cart->insert($data);
        }
        redirect('cart/view_cart');
    }
    
    ////
    function view_cart(){
        
        $data['custom_jquery'] = '
        $("input[name=\'delete\']").click(function(){
           var status = $(this).val();
           location.href = "'.site_url('cart/delete').'/" + status;
        })';
        $data['ptitle'] = 'CoderShop | View Cart';
        $this->load->view('view_cart',$data);
    }
    
    function update(){
        
        //Get number of items in cart
        $count = $this->cart->total_items();
        
        //Get info from POST
        $item = $this->input->post('rowid');
        $qty = $this->input->post('qty');
        
        //Step through items
        for($i=0;$i < $count;$i++)
        {
            $data = array(
               'rowid' => $item[$i],
               'qty'   => $qty[$i]
            );
            $this->cart->update($data);
        }
        
        redirect('cart/view_cart');
    }
    
    function delete()
    {
        $row_id = $this->uri->segment(3,FALSE);
        $data = array('rowid'=>$row_id,
                      'qty' => 0);
