Snippets by IsItWP

Do you want to add additional classes to the enclosing div for each post in the loop? It’s easy with our code snippet. Let’s take a look at how to do it.

Instructions:

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

<?php
function additional_post_classes( $classes ) {
	global $wp_query;

	if( $wp_query->found_posts < 1 ) {
		return $classes;
	}

	if( $wp_query->current_post == 0 ) {
		$classes[] = 'post-first';
	}

	if( $wp_query->current_post % 2 ) {
		$classes[] = 'post-even';
	} else {
		$classes[] = 'post-odd';
	}

	if( $wp_query->current_post == ( $wp_query->post_count - 1 ) ) {
		$classes[] = 'post-last';
	}

	return $classes;
}
add_filter( 'post_class', 'additional_post_classes' );
?>
