Problem: I have 3 custom post types. A is related with B, and A is related with C. I have a view with C information and i want to show also B info that are related to A.
Solution: Depending on the types of post relationships, you may also need a View of post type A.
- If A-C is a one-to-many (O2M) relationship and "A" is the parent, you do not need a View of A in this case.
- If A-C is a O2M relationship and "A" is the child, there can be multiple A's related to each C, so you need a View of A.
- If A-C is a M2M relationship, there can be multiple A's related to each C, so you need a View of A, regardless of which is the parent and which is the child.
