The signup vars are way too complicated to replicate. So if something goes wrong on registration with stripe you can never get the subscription recognized anymore. It needs to look at email and subscription ID and over.
I guess the reason for the signup vars was that it was supposed to be possible with future changes to have several subscriptions per customer but that’s better implemented differently.
Yeah for someone with PHP knowledge I guess it really can’t be more than 1-2 days of work and the main part will be digging and finding the places where it’s used - needs changing of quite a few files in small bits. The problem is that the code isn’t very clean and copied together a bit.
