Adding Custom Post Types to wp_get_archives()

Are you looking for a way to enable wp_get_archives to display your custom post types? While there’s probably a plugin for this, we have created a quick code snippet that you can use to add custom post types to wp_get_archives() in WordPress.

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( 'getarchives_where' , 'ucc_getarchives_where_filter' , 10 , 2 ); 
function ucc_getarchives_where_filter( $where , $r ) { 
	$args = array( 'public' => true , '_builtin' => false ); 
	$output = 'names'; $operator = 'and';
	$post_types = get_post_types( $args , $output , $operator ); 
	$post_types = array_merge( $post_types , array( 'post','CUSTOM_POST_TYPE_NAME' ) ); 
	$post_types = "'" . implode( "' , '" , $post_types ) . "'";
	return str_replace( "post_type = 'post'" , "post_type IN ( $post_types )" , $where ); 
}
