php - Paypal IPN - 如何在监听器中获取 option_selection 的值？

Question

IPN 向我发送了 option_selection1 值，但我认为我的听众无法通过电子邮件将这些值发送给我，因为它们是 url。

在 html 表单中，买家在文本字段中输入他的选择。 IPN 将其发送给听众。

我的监听器的工作是获取数据并将详细信息通过电子邮件发送给我。

问题是:我收到的电子邮件包含所有正确的详细信息，但没有选择值。

这是表格:

Your website url:<br>
<input type="hidden" name="on0" value="website">
<input type="text" name="os0" size="30" required><br><br>
Your fb page url:<br>
<input type="hidden" name="on1" value="fb">
<input type="text" name="os1" size="30" required>

这是监听器:

<?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";

// If testing on Sandbox use: 
// $header .= "Host: www.sandbox.paypal.com:443\r\n";
$header .= "Host: www.sandbox.paypal.com:443\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

// If testing on Sandbox use:
//$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);


// assign posted variables to local variables
$item = $_POST['item_name'];
$quantity = $_POST['quantity'];
$total = $_POST['payment_gross'];
$website = $_POST['option_selection1'];
$fb = $_POST['option_selection2'];
$firstname = $_POST['first_name'];
$lastname = $_POST['last_name'];
$email = $_POST['custom'];
$id = $_POST['txn_id'];
$time = $_POST['payment_date'];



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

$mail_From = "From: noreply@domainname.com/";
$mail_To = "my@gmail.com";
$mail_Subject = "New Order Received";
$mail_Body = '';

$emailtext = '

New Order Received
-------------------------
Item: '.$item.'
Quantity: '.$quantity.'
Total paid: $ '.$total.'

Website: '.$website.'
fb: '.$fb.'


Buyer Information:
-------------------------
First Name: '.$firstname.'
Last Name: '.$lastname.'
Email: '.$email.'

-------------------------
Transaction ID: '.$id.'
Time: '.$time.'

';

mail($mail_To, $mail_Subject, $emailtext . "\n\n" . $mail_Body, $mail_From);

                        }
            }
}

?>

这是 IPN 发送给听众的消息:

&option_selection1=http://www.testwebsite.com/home.html&option_selection2=http://www.facebook.com/testpage&option_name1=websitel&option_name2=fb

这将在 $cart_items 数组中准备所有内容，以便您可以遍历这些项目并相应地提取所需的数据。

$i = 1;
$cart_items = array();
