passing voucher code after free registration

There’s a knowledge base article that discusses how to implement gift certificate vouchers:
http://www.s2member.com/kb/offering-free-coupon-code/

The trouble I’m facing is how do I pass this voucher code forward after the free registration form is submitted? I need to intercept this unique value somehow so I can mark the voucher as “used” to prevent anyone else from using it after they register.

Thanks.

The most simple method would be to use the success=”” attribute in your Pro-Form shortcode (see Dashboard -› s2Member® -› PayPal® Pro Forms -› Shortcode Attributes (Explained)) to redirect the registration form to a Thank You page.

In that URL, you’d include the voucher used, for example:

success="http://example.com/thank-you/?voucher=<?php echo $_GET['voucher']; ?>"

Then on the Thank You page you’d use some PHP to quietly read that value ($_GET[‘voucher’]) and mark it as used in your database.

When someone successfully accesses the Free Registration form, the success URL will contain the voucher code in the query string and when they successfully register and get redirected to the thank you page, the voucher code will be passed along.

Hi Raam,

Thanks. I think that will work.

Great! Let us know if you have any other questions.
