I was going through a strange issue where Author page was not showing the posts which belongs to Custom Post Types. After Googling, I found this article which shows how to include Custom Post Types for archives.php
I got inspiration from above mentioned article snippet and wrote the following snippet to modify Author.php page to include Custom Post Types
function wpbrigade_author_custom_post_types( $query ) { if( is_author() && empty( $query->query_vars['suppress_filters'] ) ) { $query->set( 'post_type', array( 'post', 'my-custom-post-type-here' )); return $query; } } add_filter( 'pre_get_posts', 'wpbrigade_author_custom_post_types' );
