In the WPDevDesign Facebook group a user asked:

A client wants to show specific woocommerce products attached to the specific product category archive in the sidebar,for example,there is a product category as CAR SIDE MIRRORS,and he have some products as services that provide a full installation, finish, only mirror change etc,Now he wants to show these services on category archive.The client have ACF Pro, I'm thinking about creating a relationship field to product category and to output it on frontend.BUT I'm an ACF Beginner...

This members-only tutorial provides the steps to add a Taxonomy-type of custom field for product post type, select a product category for a product via the custom field, and show that and other products that also have the same product_cat when viewing any product category archive page.

Step 1

Install and activate ACF.

Create a field group called say, "Product Fields" having a Taxonomy-type of custom field having a lable of say, "Product Category".

Set the group to appear on Product CPT.

Step 2

Step 3

Add a Easy Posts or Repeater where you would like to show the products for which the current category has been selected.

Change the query type to Advanced and set it up like so:
