Single use Discount Codes

Single use Discount Codes

Hi,
My mini-supermarket client has asked for a single use discount code for each customer that comes to the site.
I have managed to create a system whereby a customer can create their own discount code which, when used gets added to the order details in the database.

But, in order to ensure the code can only be used once, the discount code entered needs to the cross referred with the order details in the database. If the code exists in the order details, it is not applied to the order, and if it does not exist in the order details table, the discount is applied.

The problem I have is creating the cross referring part in the discount codes area in the eCart object.

Does anyone have any ideas?

Many thanks,

Martin

create a lookup recordset that searches the order details table and filters the discount code column on the discount code form element.

now add a set session value behavior, on the server behaivors panel, click the plus button and select eCart -> General -> Set Session Value.

Set the trigger use the lookup recordset is empty.

Set the name to "discountUsed"

Set the value to "false"


Now in the eCart object, edit the discount code rule. I addition to the triggers that are already in place, add 2 more:

Session variable discountUsed exists

AND
Based on session variable value:
If the session discountUsed has a value equal to false


you may have to make sure that the set session value code is after the lookup recordset code.
