I have a post type called customer, and another called case-study. Each customer can have multiple case studies connected to it. The connection type is case-study_to_customer. I'm trying to get a list of customers, with their connected case studies.
I'm using WP_Query to get the customers, and then I am using WP_Query to get the case studies, passing the following parameters in the array:
This second query fails with an error: "Could not find direction(s)."
Does p2p support retrieving related records like this? If not, what is a better way of doing it?
