我在我的网站上设置PayPal IPN来管理订阅支付，取得了一些中等程度的成功。我目前已经在PayPal fine中设置了付款，并且将完成的付款从PayPal沙箱发送到我的IPN工作得很好，并将MySQL行设置为is_paid而不是No，这反过来又允许用户登录。

我现在想知道，当用户的订阅支付失败或取消时，IPN如何让我知道(现实世界中发生的所有糟糕和令人讨厌的事情！)我想让IPN给管理员发一封邮件

<?php
// tell PHP to log errors to ipn_errors.log in this directory
ini_set('log_errors', true);
ini_set('error_log', dirname(__FILE__).'/ipn_errors.log');

// intantiate the IPN listener
include('ipnlistener.php');
$listener = new IpnListener();

// tell the IPN listener to use the PayPal test sandbox
$listener->use_sandbox = true;

// try to process the IPN POST
try {
    $listener->requirePostMethod();
    $verified = $listener->processIpn();
} catch (Exception $e) {
    error_log($e->getMessage());
    exit(0);
}

// TODO: Handle IPN Response here

if ($verified) {

    $errmsg = '';   // stores errors from fraud checks

    // 1. Make sure the payment status is "Completed" 
    if ($_POST['payment_status'] != 'Completed') { 
        // simply ignore any IPN that is not completed
        exit(0); 
    }

    // 2. Make sure seller email matches your primary account email.
    if ($_POST['receiver_email'] != 'EMAILHERE') {
        $errmsg .= "'receiver_email' does not match: ";
        $errmsg .= $_POST['receiver_email']."\n";
    }

    // 3. Make sure the amount(s) paid match
    if ($_POST['mc_gross'] != '3.99') {
        $errmsg .= "'mc_gross' does not match: ";
        $errmsg .= $_POST['mc_gross']."\n";
    }

    // 4. Make sure the currency code matches
    if ($_POST['mc_currency'] != 'GBP') {
        $errmsg .= "'mc_currency' does not match: ";
        $errmsg .= $_POST['mc_currency']."\n";
    }

    // 5. Ensure the transaction is not a duplicate.
    mysql_connect('', '', '') or exit(0);
    mysql_select_db('') or exit(0);

    $txn_id = mysql_real_escape_string($_POST['txn_id']);
    $sql = "SELECT COUNT(*) FROM payments WHERE txn_id = '$txn_id'";
    $r = mysql_query($sql);

    if (!$r) {
        error_log(mysql_error());
        exit(0);
    }

    $exists = mysql_result($r, 0);
    mysql_free_result($r);

    if ($exists) {
        $errmsg .= "'txn_id' has already been processed: ".$_POST['txn_id']."\n";
    }

    if (!empty($errmsg)) {

        // manually investigate errors from the fraud checking
        $body = "IPN failed fraud checks: \n$errmsg\n\n";
        $body .= $listener->getTextReport();
        mail('EMAILHERE', 'PayPal IPN Fraud Warning', $body);

将这些代码添加到您的代码中，并将//电子邮件代码//注释更改为您的电子邮件代码，它将正常工作。

之前：

if ($_POST['payment_status'] != 'Completed') {

添加：

// denied payment
if ($_POST['payment_status'] == 'Denied') { 
// email code
exit(0);
}

// failed subscription payment
if ($_POST['txn_type'] == 'subscr_failed') { 
// email code
exit(0);
}

// canceled subscription
if ($_POST['txn_type'] == 'subscr_cancel') { 
// email code
exit(0);
}

只需在评论中创建发送电子邮件所需的内容。
