if ( 'publish' !== $new_status or 'publish' === $old_status ) return; if( has_term( 'oberbayern', 'event_category' ) ) 
{ $spielern = get_users( array ( 'role' => 'oberbayern' ) );
$emails      = array (); foreach ( $spielern as $spieler ) $emails[] = $spieler->user_email; 
$post_title = get_the_title( $post_id );
$post_url = get_permalink( $post_id );
$subject = 'Das Spiel wurde verschoben';
$message .= "Das Spiel\n -> ".
