I was looking for something to tie the users in a bit more than .... "the cart is empty".
This is a very simple submission.
You will have to modify the theme function to match your them.
1) in the theme folder for the theme that you are using (i.e. /themes/iron_picket_red/) create a file called template.php.
2) open file and paste these contents in.
3) find "iron_pickets_red" and replace with your actual theme name.
// $Id: template.php,v 22.214.171.124 2007/04/18 03:38:59 drumm Exp $
function iron_pickets_red_uc_empty_cart ()
return '<p>'. t('There are no products in your shopping cart.') . '</p>' .
'<br /><p>At <strong>IronPickets.Com</strong> we appreciate the opportunity to help you with your home improvement needs. If you are having trouble getting started, check out our catalog below:</p>'
. theme_uc_catalog_browse ();
Now you will have a catalog displayed on the cart page when it is empty.
