PHP webform — получение в письме только имени вложения, а не исходного вложения

Webform работает нормально, кроме вложений электронной почты. Я получаю только имя вложения в письме. К письму следует приложить оригинальный файл. Любая помощь?

Проверьте приведенные ниже коды & дайте мне знать, как я могу решить эту проблему.

Заранее спасибо.
