<?php
if(isset($_GET['tx']))
{
$tx = $_GET['tx'];
$your_pdt_identity_token = //token
$request = curl_init();
// Set request options
curl_setopt_array($request, array
(
CURLOPT_URL => 'https://www.sandbox.paypal.com/cgi-bin/webscr', //sandbox!!!
CURLOPT_POST => TRUE,
CURLOPT_POSTFIELDS => http_build_query(array
(
'cmd' => '_notify-synch',
'tx' => $tx,
'at' => $your_pdt_identity_token,
)),
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_HEADER => FALSE,
// CURLOPT_SSL_VERIFYPEER => TRUE,
// CURLOPT_CAINFO => 'cacert.pem',
));
// Execute request and get response and status code
$response = curl_exec($request);
$status = curl_getinfo($request, CURLINFO_HTTP_CODE);
// Close connection
curl_close($request);
}
if($status == 200 AND strpos($response, 'SUCCESS') === 0)
{
$singlequantity = explode("\n",$response);
$email = $singlequantity[15];
$count = null;
$email = preg_replace('"%40"', '#', $email, -1, $count);
preg_match("/payer_email=(.*)/", $email, $email);
}
else
{
echo '<script type="text/javascript">
window.location="cancel.php";
</script>';
}
?>
i know i shoved it in real hard right now , but this might be useful to other users attempting to do this.
