Override Genesis Archive Settings for CPT

Add the following code to your WordPress theme’s function.php file, or a functionality plugin to replace a post’s content with the post’s excerpt.

<?php

// Portfolio Archive Excerpt
add_action( 'genesis_before_loop', 'excerpt_content_specific_category' );
function excerpt_content_specific_category() {
  if (is_post_type_archive('portfolio')) {
		remove_action( 'genesis_entry_content', 'genesis_do_post_content' );
		add_action( 'genesis_entry_content', 'do_post_content' );
	}
}
function do_post_content() {
	the_excerpt();
}
