I've searched the forums and read the PayPal documentation but I can't figure out an anser to my simple task.
My order is submitting to PayPal correctly and processing correctly. I need the IPN to set a session for the item_number so that I can use it in later processing, but I can get the IPN to set a session. My code is below. What do I have wrong? Or can't I use IPN to set a session? Thanks.
session_start();
// Include the paypal library
include_once ('Paypal.php');
// Create an instance of the paypal library
$myPaypal = new Paypal();
// Log the IPN results
$myPaypal->ipnLog = TRUE;
// Enable test mode if needed
$myPaypal->enableTestMode();
// Check validity and write down it
// PHP 4.1
// 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);
// 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) {
session_register('item_number');
$_SESSION['item_number'] = $_POST['item_number'];
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
