Has anyone tackled creating a custom post which leverages posts-to-posts relationship via the front end. Here is what I am trying to do.
I have two custom content type: events and participants
participants can have many events
events can have many participants
From admin, this is working fine via posts-to-posts. However, I need to have users via the front end associate events and participants without having to go through the wp admin site or add events/participants and then associate to participants/events.
