購買後發送電子郵件

Question

我有一個捐贈網站。我希望得到發送給我的捐款後收到一個電子郵件與買家用戶名作爲進入這裏：

<input type="text" name="custom" value="Enter your Minecraft username here!"><br /><br /> 

我怎麼會去考慮該用戶名和發送，在郵件到我的郵箱？

這裏是貝寶IPN：

Answer 1

假設你的代碼的其餘部分是有效的，你可以只把下面剛過mysql_close($con);

廣場這樣的事情有：

mail("youremail@example.com", "Donation received", "You have received a new payment from ".$custom.""); 

將youremail@example.com替換爲您希望收到這些郵件的mailaddress。

因此，最終的代碼如下所示：

mysql_close($con); 
    mail("youremail@example.com", "Donation received", "You have received a new payment from ".$custom.""); 
}
