Question

我希望有人能指出我正确的方向。

我在一个网站上创建了一个IPN监听器，目前它适用于订阅的人并创建他们的PIN号，将他们的登录（电子邮件和随机生成的PIN）添加到数据库而不会出现问题。然后，他们可以在收到包含详细信息的电子邮件后登录下载区域。

注册效果很好 - 但是，当他们取消订阅时，Paypal会清楚地发送通知，而IPN只是发出新的登录信息而且我不知道如何编写代码来发送“抱歉你” “离开”电子邮件并将其从数据库中删除。

非常感谢任何帮助！

以下脚本;

<?php

mysql_connect("xxxx", "xxxx", "xxxx") or die(mysql_error());
mysql_select_db("xxxx") or die(mysql_error());


// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30); 

if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {

// PAYMENT VALIDATED & VERIFIED!

$email = $_POST['payer_email'];
$password = mt_rand(1000, 9999);

mysql_query("INSERT INTO users (email, password) VALUES('". mysql_escape_string($email) ."', '".md5($password)."' ) ") or die(mysql_error()); 

$to      = $email;
$subject = 'xxx Download Area | Login credentials';
$message = '

Your account information
-------------------------
Email: '.$email.'
Password: '.$password.'
-------------------------

You can now login at xxxxx';
$headers = 'From:xxx@xxx.co.uk' . "\r\n";

mail($to, $subject, $message, $headers);



}

else if (strcmp ($res, "INVALID") == 0) {

// PAYMENT INVALID & INVESTIGATE MANUALY!

$to      = 'paypal@xxx.co.uk';
$subject = 'xxx Download Area | Invalid Payment';
$message = '

Dear xxx,

Please verify the payment manually and contact the buyer.

Please contact xxx at xxx on xxx if you need additional help, the buyers email is below;

$headers = 'From:noreply@xxx.co.uk' . "\r\n";

mail($to, $subject, $message, $headers);

}
}
fclose ($fp);
}

只需添加一个开关，检查与ipn一起发送的txn_type的类型。这只是我的头脑，但试一试.....

$email = $_POST['payer_email'];               

switch ($_POST['txn_type']) {
          case 'web_accept':
            //you received a payment such as a buy now button
            //so now lets do things such as trigger a call to a 
            //function to create an email or add POST vars to a database
            $this->createUser($email, $password);
            $this->createEmail($email, $password);
          break;
          case 'subscr_signup':
            //This shows that someone has subscribed using a subscribe button
            //We can do anything here such as increase the users access level
          break;
          case 'subscr_payment':
            //payment for a subscribed user has just been made
            //do something such as send them a conformation email
          break;
          case 'subscr_eot':
            //this is a End Of Terms meaning that the subscriber either canceled or
            //paypal could not process the payment due to the user not having the funds
            //lets remove them from our database and send them an email
            $this->removeUser($email);
          break;
    case 'subscr_cancel':
            //Here the user canceled their account so lets remove them and send an email
            $this->removeUser($email);
          break;
        }

       function createEmail($email, $password)
       {

        $to      = $email;               
        $subject = 'xxx Download Area | Login credentials';               
        $message = '               

        Thank you for your purchase               

        Your account information               
        -------------------------               
        Email: '.$email.'               
        Password: '.$password.'               
        -------------------------               

        You can now login at xxxxx';               
        $headers = 'From:xxx@xxx.co.uk' . "\r\n";               

        mail($to, $subject, $message, $headers);               

       }

       function createUser($email, $password)
       {
       mysql_query("INSERT INTO users (email, password) VALUES('". mysql_escape_string($email) ."', '".md5($password)."' ) ") or die(mysql_error());
       }

沿着这些方向的东西应至少让你朝着正确的方向前进。

Paypal IPN取消订阅，发送新登录？
