Reply To: display CPT next to post title

Sorry, there was an error in that code, please use this one:

add_filter( 'asp_results', 'asp_show_the_post_type', 10, 1 );
function asp_show_the_post_type( $results ) {
  foreach ($results as $k=>&$r) {
		if ( isset($r->post_type) ) {
			// Modify the post title
			$r->title = get_post_type( $r->id ) . ' - ' . $r->title;
		}
  }

  return $results;
}
