Hi everybody.
I'm currently trying to implement a subscription system that allows users to gain access to all content tagged under a certain category. My first thought was to do role-granting, but there will be at least 10-20 categories, and that would simply be cumbersome.
In addition to category subscriptions, I'd also like to do per-user subscriptions-- so if you like what Bob Smith has written, you can buy a monthly recurring subscription to his posts for $x.xx.
While I have some experience with PHP, and know my way around a drupal config-- I don't have terribly much experience with actual under-the-hood development. I'm wondering if you guys have suggestions for how to implement this system? Is there a contrib feature somewhere that I'm missing that allows this?
If not-- what hooks would i need to override to create something like this?
