Add Post ID class to each listing item

Display Posts adds a class of .listing-item to each post in the listing. You can customize the classes using the display_posts_shortcode_post_class filter.

The following code adds a class to each listing item of post-{id} , so if the post has an ID of 123 it will have a class of post-123.

This code snippet goes in a core functionality plugin or Code Snippets.

 * Display Posts - post ID class 
 * @see
 * @param array $classes
 * @param object $post
 * @return array $classes
function be_dps_post_id_class( $classes, $post ) {
	$classes[] = 'post-' . get_the_ID();
	return $classes;
add_filter( 'display_posts_shortcode_post_class', 'be_dps_post_id_class', 10, 2 );
