fractalspin,
Your problem is right here...
Code:
xcart_pricing 1 xcart_featured_products,
This means while the $direction is working its not being translated...
Might try something like this..
Code:
case "add_date":
if ($direction == '1'){
$direction_var = 'DESC';
}
if ($direction == '0') {
$direction_var = 'ASC';
}
$sort_string = "$sql_tbl[products].add_date $direction_var";
break;
