Show Custom Post Types on the Homepage

Custom post types are commonly used on WordPress sites, but they don’t show on the homepage or in the archive pages unless you write code to do that.  I’ve put together some code that is smart about detecting your public custom post types and automatically adding them to your homepage and archive pages:

 * Show WordPress custom post types on the main blog and archive pages
 * @param WP_Query $query
function show_custom_post_types( $query ) {

  // Show all custom post types on main blog and archive pages
  if ( $query->is_main_query() && ( is_home() || ( is_archive() && !is_post_type_archive() ) ) ) {

    $custom_post_types = get_post_types( array(
       'public' => true,
       '_builtin' => false,
    ) );
    $post_types = array_merge( array('post'), $custom_post_types );
    $query->set( 'post_type', $post_types );

   return $query;

add_filter( 'pre_get_posts', 'show_custom_post_types' );

  1. Great snippet Micah, thanks. I would optimize the snippet by moving the get_post_types() call inside the conditional statement though. Saves a SQL query for every page request. 🙂
