Code Samples: Add Custom Post Types to Author Archives

By default, WordPress only includes ‘posts’ in the Author Archive. To fix this, you need to modify the pre_get_posts filter to accommodate for your missing post types.

function post_types_author_archives($query) {

	// Add ‘videos’ post type to author archives
	// Add your own Post types in single quotes before 'post'
	if ( $query->is_author ) {
		$query->set( 'post_type', array('videos','post') );
		// Remove the action after it’s run
		remove_action( 'pre_get_posts', 'post_types_author_archives' );
	}
}
add_action( 'pre_get_posts', 'post_types_author_archives' );
