Paypal IPN Problems

[Mike]

Does anyone have any idea why I would be receiving this e-mail?

I'm using a script for Paypal that I found.

P.S. The script works fine, and the payment goes through fine. But then I receive this e-mail after.

<?php
include('includes/config.php');
include('includes/functions.php');

    $invoiceid = clean($_GET['invoiceid']);

    $query = mysql_query("SELECT * FROM `orders` WHERE `invoiceid` = '$invoiceid'");
        while($row = mysql_fetch_assoc($query)) {
            $totalcost = $row['totalcost'];
            $email = $row['email'];

// PayPal settings
$paypal_email = 'myemailgoeshere@hotmail.com';
$return_url = 'rsgp.php';
$cancel_url = 'rsgp.php';
$notify_url = 'rsgp.php';
$item_number = 1;
$item_name = 'Runescape Gold';
$item_amount = $totalcost;

}

    $qry = mysql_query("UPDATE `orders` SET `complete` = '1' WHERE `invoiceid` = '$invoiceid'");

// Check if paypal request or response
if (!isset($_POST["txn_id"]) && !isset($_POST["txn_type"])){

    // Firstly Append paypal account to querystring
    $querystring .= "?business=".urlencode($paypal_email)."&";    
    
    // Append amount& currency (£) to quersytring so it cannot be edited in html
    
    //The item name and amount can be brought in dynamically by querying the $_POST['item_number'] variable.
    $querystring .= "item_name=".urlencode($item_name)."&";
    $querystring .= "amount=".urlencode($item_amount)."&";
    
    //loop for posted values and append to querystring
    foreach($_POST as $key => $value){
        $value = urlencode(stripslashes($value));
        $querystring .= "$key=$value&";
    }
    
    // Append paypal return addresses
    $querystring .= "return=".urlencode(stripslashes($return_url))."&";
    $querystring .= "cancel_return=".urlencode(stripslashes($cancel_url))."&";
    $querystring .= "notify_url=".urlencode($notify_url);
    
    // Append querystring with custom field
    //$querystring .= "&custom=".USERID;
    
    // Redirect to paypal IPN
    echo '<meta http-equiv="REFRESH" content="0;url=https://paypal.com/cgi-bin/webscr' . $querystring . '">';
    exit();

}else{
    
    // Response from Paypal

    // read the post from PayPal system and add 'cmd'
    $req = 'cmd=_notify-validate';
    foreach ($_POST as $key => $value) {
        $value = urlencode(stripslashes($value));
        $value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
        $req .= "&$key=$value";
    }

    $data['item_name']            = $_POST['item_name'];

$return_url = 'rsgp.php';
$cancel_url = 'rsgp.php';
$notify_url = 'rsgp.php';

I believe that has to be your full website URL.

$return_url = 'http://site.com/rsgp.php';
$cancel_url = 'http://site.com/rsgp.php';
$notify_url = 'http://site.com/rsgp.php';

Yep, the URLs have to be valid urls, not relative links to files.
