Er wordt gebruik gemaakt van 2 functies. 1 om een uniek ID te genereren en 1 om de coupon aan te maken. De expiry date kan worden aangepast naar een datum die wenselijk is zoals in het voorbeeld. Het email adres kan opgehaald worden vanuit een gforms veld zodat de coupon kan worden ingeleverd door dezelfde persoon die het formulier verzend.
In functions.php
// Genereer coupon code by verzenden Gforms.
