Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

add_filter( 'post_class', 'wps_first_post_class' );
function wps_first_post_class( $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?

    Thanks

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