I have a WordPress Multisite installed (single domain + subfolders – each instance for a different country – so multiple languages but for now single currency – euro)
Users are automatically added to all instances (using “Join my site”) – so you can use your login on all instances.
Now the problem is:
We want to launch a premium subscription-based membership (which would then active discounts).
When a user purchase a subscription on one site, he is granted a membership plan. Now the question is, how can I automatically activate it on all instances?
I was thinking to run some code when it’s purchased that gift it to the same user on all other instances.
But maybe there is a plugin for that? Or something similar that I could use as base to build on?
Or some API doc that could be useful? I am bit clueless how to start here.
