   Example migrated from Codex:

   Append the query string for posts to permalink URLs (uses add_query_arg):

   function append_query_string( $url, $post, $leavename=false ) {
   	if ( $post->post_type == 'post' ) {
   		$url = add_query_arg( 'foo', 'bar', $url );
   	}
   	return $url;
   }
   add_filter( 'post_link', 'append_query_string', 10, 3 );

   For other post types, use the following filters:

   • page: page_link
   • attachment: attachment_link
   • Custom post types: post_type_link

   • There is also term_link for archive pages, such as categories.

   /**
    * Filter to remove a particular slug from post urls
    */
   function remove_slug_from_URL($permalink) {
   	$new_link = str_replace('/slug-to-remove', '', $permalink);
   	return $new_link;
   }
   add_filter( 'post_link', 'remove_slug_from_URL', 10, 1);

   Used to remove parent category slug from permalinks and maintain subcategories in URL
