This is quick and simple mod, but I thought it was needed for computer luddites out there.
If you enter in a gift certificate and happen to copy the previous or trailing blanks space around the number, you will get an invalid gift certificate error. Here's how to fix it (it's easy):
In your payment/payment_giftcert.php file...
Change this:
Code:
#
# Checking GC if it's already applied to order
#
$gc_applied = false;
to this
Code:
#
# Checking GC if it's already applied to order
#
$gcid = trim($gcid);
$gc_applied = false;
Pretty simple, but it works really well and will help cut down on errors and the subsequent support inquiries.
