I don’t think there exist one, but you could create your own, wpse_empty_trash, with something like this: /** * Add a custom hook ‘wpse_empty_trash’ */ add_action( ‘load-edit.php’, function() { add_action( ‘before_delete_post’, function ( $post_id ) { if ( ‘trash’ === get_post_status( $post_id ) && filter_input( INPUT_GET, ‘delete_all’ ) && 1 === did_action( ‘before_delete_post ‘ ) … Read more

This will do it: (add to your theme’s functions.php) add_action( ‘pre_get_posts’, ‘set_posts_per_page’ ); function set_posts_per_page( $query ) { global $wp_the_query; if ( ( ! is_admin() ) && ( $query === $wp_the_query ) && ( $query->is_search() ) ) { $query->set( ‘posts_per_page’, 3 ); } elseif ( ( ! is_admin() ) && ( $query === $wp_the_query ) … Read more
My approach. No extra function, no filter. 🙂 <?php $GLOBALS[‘wpdb’]->current_post = 0; ?> <div <?php post_class( 0 === ++$GLOBALS[‘wpdb’]->current_post % 3 ? ‘third’ : ” ); ?>> Alternative: <div <?php post_class( 0 === ++$GLOBALS[‘wpdb’]->wpse_post_counter % 3 ? ‘third’ : ” ); ?>>
