This snippet of code will fetch the 10 most recent posts that are featured.
``<?php $featured_posts = new WP_Query( array( 'post_type' => 'post', 'posts_per_page' => 10, 'tax_query' => array( array( 'taxonomy' => 'pts_feature_tax', 'field' => 'slug', 'terms' => array( 'featured' ), ) ) ) );
if ( $featured_posts->have_posts() ) : while ( $featured_posts->have_posts() ) : $featured_posts->the_post();
//output featured posts here
endwhile; endif;
?>``
