}

echo json_encode($result);
die;
}
}

EmiPrivateMessages::init();

?>

y tu pregunta cual es?...

Al parecer en esta parte:

public static function notify(){
global $wpdb, $current_user;

$intTotalUnread = self::$DB->getTotalUnread($current_user->ID);

if(empty($intTotalUnread)) {
$intTotalUnread = 0;
}

if($intTotalUnread>0 && ('wp_head') && (!isset($_REQUEST['page']) || $_REQUEST['page'] != 'emiPrivateMessages_inbox' || $_REQUEST['page'] != 'emiPrivateMessages_dialog' )) {
echo '<div id="message" class="error"><p><b>', sprintf( _n( '¡Usted tiene %d nuevo mensaje!', '¡Usted tiene %d nuevos mensajes!', $intTotalUnread, 'emiPrivateMessages' ), $intTotalUnread ), '</b> <a href="admin.php?page=emiPrivateMessages_inbox">', __( 'Ir a la Bandeja', 'emiPrivateMessages' ), ' &raquo;</a></p></div>';
}
}

es donde muestra Screenshot by Lightshot (¡Usted tiene 1 nuevo mensaje! Ir a la Bandeja)

Quisiera saber si alguien me puede ayudar con el código para que esta notificación aparezca también en la barra superior de Wordpress o en la parte superior de la cabecera de mi web y agregarlo al plugin.

Gracias de antemano.
