Cześć. Borykam się z tym od kilku dni i nie wiem jak dodać dane z formularza. które poda osoba odwiedzająca naszą stronę czyli: imię i nazwisko, e-maila, czy numer telefonu w treści wiadomości( w jej nagłówku) Z góry Wam dziękuję za pomoc.
Problem rozwiązany

Dodałem taką linijke do kodu poniżej:

[PHP] pobierz, plaintext 
$mail->Body = '<h1 align=centre>Imię i nazwisko: '.$_POST['userName'].'<br>Telefon: '.$_POST['userPhone'].'<br>E-mail: '.$_POST['userEmail'].'<br><br>'.$_POST['userMessage'];

Ale porady odnośnie kodu i jego poprawy mile widziane.
