Add class to first post in the loop

If you wanted to add emphasis to the first post in your blog adding this snippet to the functions.php of your wordpress theme will add the class of "first" to your first post.

add_filter( 'post_class', 'wps_first_post_class' );
function wps_first_post_class( $classes ) {
    global $wp_query;
    if( 0 == $wp_query->current_post )
        $classes[] = 'first';
        return $classes;

  1. Yeah! for adding a last class to the post, need only to add a condition like $wp_query->current_post === $wp_query->found_posts?

    1. Something like this should work,
      if( $wp_query->current_post == $wp_query->post_count-1 )

      1. Thank you man, i was unsafe about found_posts start from 0 (my bad). However, in same cases post_count isn’t a right choice because it contain the total number of posts being displayed. The use of found_posts or post_count depend which query had been performed, post_count have the same value of “posts_per_page” if is defined in a query or the default value defined into the read settings (sorry for my english).

        1. Hi Widzo, I think it depends on the results you want, if you want to add the class to the last post on every page you would use “post_count” on the very last post only you would use “found_post”

  2. great! And if I want to add a class always to the fourth column of the loop? For example, I have a loop showing my posts into 4 columns and I need to add this class to the right column. How can I do that?


    1. Hi Fabio, I would need to see your columns loop in order to see what would need to be done.
