Paypal IPN
Hi,
I am trying to setup paypal's IPN system, but using the ipn simulator i am unable to get any 'VERIFIED' responses.
Here is the code i am using:
PHP Code:
<?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/1.1\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Host: www.paypal.com\r\n";
$header .= "Connection: close\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);
//
//error connecting to paypal
if (!$fp) {
//
}
//successful connection
if ($fp) {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
$res = trim($res); //NEW & IMPORTANT
if (strcmp($res, "VERIFIED") == 0) {
//insert order into database
//SEND EMAIL
$to = "[email protected]";
$subject = "Good IPN";
$message = " this is working ipn" . $payment_status . $item_name;
$from = "[email protected]";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
}
if (strcmp ($res, "INVALID") == 0) {
//insert into DB in a table for bad payments for you to process later
//SEND EMAIL
$to = "[email protected]";
$subject = "Bad IPN";
$message = "this is not working ipn";
$from = "[email protected]";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
}
}
fclose($fp);
}
?>
Thanks, Chris.
