Hi @gleenk
Thanks for the link. I’ll have a read over it, but from what I can see, I don’t think ACF can provide a simple API interface for this.
This is due to the simple nature of the WP_Query object and the meta_query param. Basically, WP only allows for a simple 1 value match, but doesn’t allow you to do much else.
Custom ordering based on a sub field relationship is just too custom to wrap up into the core. You will need to follow the code provided to re design the array, then sort it.
If you can think of an easy way to package it into the core, I would love to hear your thoughts.
Thanks
