This members-only tutorial provides the steps to limit the posts output by a Oxygen's Easy Posts or Repeater component on singular entries of another post type to only those that belong to the terms selected using ACF's Taxonomy custom field.
Sample Scenario:
tutor Custom Post Type uses the standard WordPress categories Ex.: Maths, Science, Geography.
Advanced Custom Fields field group has a tutor_category_selector custom field of type Taxonomy set to appear on regular Posts.
When editing a Post, Maths and Science are ticked.
The objective is to show a section on singular posts that shows all the tutors that are filtered by the selected categories.
Step 1
If you have not already, register your CPT using a plugin like CPT UI or otherwise, tick support for categories and add a few entries while setting some categories.
Step 2
Add your field group.
Leave the Return Value as Term ID.
Step 3
In your post edit screens, select the taxonomy terms that the current post should be "related to".
Step 4
Edit the Oxygen Template that applies to singular posts.
Add a Section.
Add a Easy Posts or Repeater.
Set to Query to custom (or manual, if you prefer that) and select/set your Post Type and optionally, the Count or posts_per_page.
Add a Code Block above the Easy Posts/Repeater.
