Add breadcrumbs to Genesis Portfolio Pro archives and single pages

functions.php

<?php
//* Do NOT include the opening php tag

//* Add the breadcrumb navigation to portfolio archives and single pages
add_action( 'genesis_before_loop', 'add_portfolio_breadcrumb' );
function add_portfolio_breadcrumb() {
if ( get_post_type( $post_id ) == 'portfolio' || is_post_type_archive( 'portfolio' ) || is_tax( 'portfolio-type' ) ) {
	add_action( 'genesis_before_loop', 'genesis_do_breadcrumbs', 15 );
        }
}

Ryan,

Thanks for posting this. Is sounds like what I'm looking for. A breadcrumb so that users can click back easily, as the Portfolio plugin doesn't keep the Nav item highlighted when in a portfolio item page.

I tried pasting this at the top of the functions.php file, but when I saved and reloaded the page, it just posted the code to the top of all the pages on the site.

Can you tell me where the code goes?

thanks
