How do you display the archives of a Custom Post Type by Year & Month?
Yes, you can.
All you need is make a filter for wp_get_archives();
so it accepts post_type
parameter:
function my_custom_post_type_archive_where($where,$args){
$post_type = isset($args['post_type']) ? $args['post_type'] : 'post';
$where = "WHERE post_type="$post_type" AND post_status="publish"";
return $where;
}
then call this:
add_filter( 'getarchives_where','my_custom_post_type_archive_where',10,2);
Whenever you want to display archive by custom post type, just pass the post_type args:
$args = array(
'post_type' => 'your_custom_post_type',
'type' => 'monthly',
'echo' => 0
);
echo '<ul>'.wp_get_archives($args).'</ul>';
