我有以下用于贝宝交易的发布按钮:
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="my@email.com">
<input type="hidden" name="item_name" value="Item description">
<input type="hidden" name="item_number" value="1">
<input type="hidden" name="amount" value="00.30">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="bn" value="PP-BuyNowBF">
<input type="hidden" name="return" value="website.com/index.php" />
<input type="hidden" name="cancel_return" value="website.com/index.php" />
<input type="hidden" name="rm" value="2">
<input type="hidden" name="notify_url" value="website.com/ipn/ipn.php">
<input type="hidden" name="custom" value="user_id">
<input type="submit" value="upgrade" />
</form>
以及 ipn.php 中的以下代码
<?php
include_once 'config.php';
// 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);
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
mysql_query("UPDATE table SET column='1' WHERE column2='13'");
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
?>
当我点击升级按钮并付款时,它没有显示返回网站按钮...但是有一个返回 my@email.com 按钮,它有 10 秒的延迟并将我带回我的网站...虽然它会弹出一个关于加密数据的警告,但我不知道它是什么。
我在 ipn.php 中使用的查询也不执行。我什至不知道它是否转到 ipn.php。
