Passing Variables to a URL
Posted: Mon Jul 19, 2010 6:17 am
I have some code that I dont exactly undertsand and wanted some help adding to.
I believe this code uses an external link (paypal) and passes additional variables to the URL?
Could I simply add to the URL by passing in an additional variable?

Code: Select all
// 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'];
$custom = $_POST['custom'];
if (!$fp) {
// HTTP ERROR
} else {
