It works!
Here is the code:
in cart.php
Code:
Change this in the redirect section:
if(!empty($HTTP_REFERER)) {
func_header_location($HTTP_REFERER);
to this:
if(!empty($HTTP_REFERER)) {
func_header_location($HTTP_REFERER.'$page&addedtocart=1');
In customer/product.tpl
I added this code from Jon after the add to cart button code:
Code:
{if $smarty.get.addedtocart eq "1"}
Product has been added to cart
{/if}
I just use text but it could have been a language var like
Code:
{if $smarty.get.addedtocart eq "1"}
{$lng.txt_product_added_announ}
{/if}
and added that var in the language area of the cart admin.
