Issue with Custom Post Types

    Background

    I have enabled multiple post types on my site and I am using the same tags across all post types. The first issue that I had was the custom posts where not appearing in the tag archive. I found a solution to the issue on this page which suggested adding the following code into my functions.php file which resolved the issue. 

    add_filter('pre_get_posts', 'query_post_type');
function query_post_type($query) {
  if(is_tag()) {
    $post_type = get_query_var('post_type');
	if($post_type)
	    $post_type = $post_type;
	else
	    $post_type = array('post','video'); // replace cpt to your custom post type
    $query->set('post_type',$post_type);
	return $query;
    }
}

    New Problem

    Since adding the code, when I save a post (standard post or custom page), I get a PHP error despite the post saving successfully.

    Warning: Cannot modify header information – headers already sent by (output started at /home/tbassett/webapps/thetennisbulletin/wp-content/themes/StudioBlue/functions.php:61) in /home/tbassett/webapps/thetennisbulletin/wp-includes/pluggable.php on line 881

    Try it with this:

    add_action('pre_get_posts', 'query_post_type');
function query_post_type($query) {
	// do not alter the query on wp-admin pages and only alter it if it's the main query
	if (!is_admin() && $query->is_main_query()){

		if(is_tag()) {
			$query->set('post_type', array('post','video'));
		}

	}
}
