In the comments section of Custom Shortcode for Primary Category Link in Genesis Entry Meta using ACF tutorial, a user asked:
Hello Sridhar! This is helpful. Do you know how we could customize this to use the Yoast Primary Category instead?
Since version 3.1, Yoast SEO plugin supports designating a category as the primary category in post editor screen in WordPress.
In this tutorial, we shall create a custom primary_post_category shortcode which returns the linked Yoast SEO primary category and use genesis_post_meta filter hook to check if Yoast SEO is active and if so, whether a category has been set as the primary category and if so, call our custom shortcode instead of the default Genesis post_categories shortcode.
This way, only if the Yoast SEO plugin is active and only if a category has been marked as primary will the post meta show it. Otherwise, the standard post meta.
