empty cart, return to home page

I would like to mod the system so that when a customer empties their cart on the shopping cart page, they will be automatically returned to the main index page of the site?

I assume it will require tweaking of the code in the tpl_shopping_cart_default.php somewhere around line 180?

I just have no idea how to implement a command for an auto return like that?

Anybody know this?

Better to go into includes/modules/pages/shopping_cart/header_php.php

Try this at about line 60 or so

$products = $_SESSION['cart']->get_products();

if(!count($products))
{
zen_redirect(zen_href_link('index', '', 'SSL'));
}

the first line already exists the rest just add underneath it. It will go to the home page whenever the cart is empty.

edit --------------------------
whoops - you don't need it to be SSL so just take that out. Sorry

zen_redirect(zen_href_link('index'));

perfect! thanks!!
