thinking they would solve my issue, but I’m not wrapping my head around it I think. Here’s my scenario:
Home Builder Website
I have Custom Post Types:
Floor Plans
Neighborhoods
I have these relationships set up:
Floor Plans
– Relationship: Filter by post type: Neighborhood
Neighborhood
– Relationship: Filter by post type: Floor Plan
So when I add that Floor Plan A is available in Neighborhood A, it shows up on the front end in the right place.
HOWEVER, what I would prefer to happen on the backend is when I add Floor Plan A, and select that it is available in Neighborhood A, when I go to Neighborhood A, it has automatically updated the available floor plans to include Floor Plan A.
I *thought* maybe the Post2Post plugin would help with that, but it seems to be for integrating the same information on different post types, instead of what I outlined above.
