A user asks:
I need help please, with querying an ACF relationship field on a single CPT template.
Here's the scenario:
I have two Custom Post Types (CPTs) - "Branches" and "Services". These two CPTs are linked by an ACF relationship field, allowing me to choose which services are related to a branch and vice versa.
The "Services" CPT has a taxonomy called "Service Category", which includes categories like Massages, Facials, Nail Care, etc. This structure allows me to group the service posts.
I've created a single template for the "Branches" post type. On this template, I aim to display the "Service Category" taxonomy and list the related services linked to a branch under the taxonomy.
This Pro tutorial provides the steps for displaying related CPT 2 posts grouped by a CPT 2's taxonomy on CPT 1 post page in Bricks.
Scenario:
CPT 1 = Branch
CPT 2 = Service
CPT 2 taxonomy = Service Category
Objective: On single branches, show related services grouped by service categories.
We shall
- Get unique service category IDs for related services of the current branch post
- Set up a Terms query with include param set to the above
- Set up an inner Posts query with service-category set to the current looping term and restrict the posts to related services
