I've seen a few questions around this topic, but unsure if it's been solved.
Basically without knowing the specific query_arg (WP_Query) array data, there isn't an easy way to filter a post selector field type.
A simple scenario:
Three Custom Post Types: author, book, collection
.
Books have a meta_key of author tied to author post IDs.
author
& selector for book
(maybe book is a multi-selector or is clonable).I would like to add a note that I have build a simple working version of this in javascript, but it's limited to a few scenarios, and as I dive deeper into selection that filter a field by post_type, taxonomy, or multi selectors (in a repeater group) the basic function I built becomes moot.
I'd like to avoid conditional logic fields, since it still wouldn't cover knowing the selections of what I am calling the field filter selectors.
Anyone build something like this? Does this seem like a custom field type?
Kinda seems like I just explained a custom field type like relationship
in ACF: https://www.advancedcustomfields.com/resources/relationship/
Hi Austin,
We have the extension MB Relationships which can help you to cover your case. It's free so you can try to create the relationship between post types and filter posts by WP_Query.
Follow this documentation for more information https://docs.metabox.io/extensions/mb-relationships/.
I was afraid you point that out, and that's not what I was getting at. I just linked up the ACF one because it's post field has two outside selectors that filter the actual post dropdown (in theirs it's by post_type and taxonomy.
Hi Austin,
I'm going to create a feature request and discuss it with the developer team to support more options for the relationship.
Thank you and have a nice day.
Thanks. I am working on an implementation, and if I feel it's not too hacky, I will share it here.
Maybe let's not call it a relationship, but, "dynamic/external post query arg controls".
