buna contact.php yazabilecek varmı? form mail göndermiyorda sanırım contact.php lazım?

kardeş bu neya.. burdaki bilgileri alıp iletecek sayfanın kodları;

<?php

$kime = "adim@sunucum.com";
$konu = $_POST['konu'];
$mesaj = $_POST['mesaj'];
$kimden = $_POST['gonderen'];

$mail = mail($kime, $konu, $mesaj, $kimden);

if($mail) { echo "Mail Gönderme Başarılı"; } else { echo "Mail Gönderme Başarısız"; }

?>

şeklindedir. umarım işinize yarar.

normal submit butonu ekleyip dene bence nssasmaz'ın verdiği kodları denemiş de olursun .
