Show discount code used in confirmation email

It's a while since I set up eCart but my client would like to be able to see which discount code was used within the confirmation email they receive - it currently shows the amount but not the code itself. Could you advise?

The discount code is usually saved in the session. You should be able to easily display the value from that session variable in the email receipt. Just update the email body file and add the value.

That's what I would have thought, however there isn't a session value showing in the confirmation email. If I open the cart page I can see the cart session values and there's one called [Present Discount Title], however if I echo that on the email page it just gives me the first of the discount codes set up, not the one that's been used:

<?php echo $VetProCart->RuleLooperName("Discounts"); ?>

There are also cart session values for each individual discount code I have set up, for example:

<?php echo $VetProCart->GetRuleValueByName("Discounts", urldecode("discountcodename")); ?>

but I'm not sure how I would use these to only display the one that's been used?

Can I see the cart page where the user enters the discount code? That might help me identify which session variable you can use.

Cart page attached.

You should be able to use:

<?php

if (isset($_SESSION["PromoCode"])) {

?>

Used promo code: <?php echo($_SESSION["PromoCode"]); ?>

<?php

}

?>

That works, many thanks!
