我已经设法设置 PDT，现在设置为 IPN。问题是即使我使用相同的代码，卖家账户确实会收到一封确认邮件，但买家却没有，这没有意义。
这是我的 IPN.php：
<?php
header('Content-type: text/html; charset=utf-8');
?>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<?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);
}
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'] != '*****') {
$errmsg .= "'receiver_email' does not match: ";
$errmsg .= $_POST['receiver_email']."\n";
}
// 3. Make sure the amount(s) paid match
/*if ($_POST['mc_gross'] != '9.99') {
$errmsg .= "'mc_gross' does not match: ";
$errmsg .= $_POST['mc_gross']."\n";
}*/
// 4. Make sure the currency code matches
if ($_POST['mc_currency'] != 'USD') {
$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']);
$sql = "SELECT COUNT(*) FROM orders WHERE txn_id = '$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('*****', 'IPN Fraud Warning', $body);
} else {
// add this order to a table of completed orders
$payer_email = mysql_real_escape_string($_POST['payer_email']);
$mc_gross = mysql_real_escape_string($_POST['mc_gross']);

if (!mysql_query($sql)) {
error_log(mysql_error());
exit(0);
}
// send user an email with a link to their digital download
$num = $_POST['num_cart_items'];
$amount = $_POST['mc_gross'];
$firstname = $_POST['first_name'];
$lastname = $_POST['last_name'];
$to = filter_var($_POST['payer_email'], FILTER_SANITIZE_EMAIL);

如果您查看它的底部，您会看到我尝试发送 2 封邮件，一封给买家，一封给卖家，其代码几乎相同（只有 mailadress 更改），但仍然只有卖家收到邮件。为什么是这样？
