title: Codeigniter Cart wrong cookie
body: <p>I embedded this example <a href="http://net.tutsplus.com/tutorials/php/how-to-build-a-shopping-cart-using-codeigniter-and-jquery/" rel="nofollow">http://net.tutsplus.com/tutorials/php/how-to-build-a-shopping-cart-using-codeigniter-and-jquery/</a>  to my shop.
  I faced an issue that $total = $this->cart->total_items(); gets quantity value.
  And if compare cookies from my site with cookie from example this is the difference:
  my ...total_items"<strong>*;i:66;</strong>*s:10:"cart_total";i:5610;}}.....
  original ...total_items*<strong>";s:1*</strong>:"1";s:10:"cart_total";s:4:"1499";...</p>
  
  <p>So as you can see cookie stores wrong. I tried logging variables in Cart library but for this moment haven't caught problem. And I have another issue, as I think related with cookie I cannot add more than 7 items in cart. But I investigated this issue a bit, and mentioned only for helping.</p>
