hi guys i am developing an eCommerce app using flex and ColdFusion and i would
like to use PayPal as a way to make payments. i stumbled on a very nice
tutorial on how to Integrate PayPal Express Checkout with Flex and Adobe AIR
(http://www.adobe.com/devnet/flex/articles/flex_paypal_02.html). the only
problem is that he uses php as the server side language and i would like to use
ColdFusion. can someone please help me to convert the following code to
ColdFusion. here it is
[b]startPaymentFlex.php[/b]
<?php
require_once 'ppNVP/CallerService.php';
require_once 'ppNVP/constants.php';
session_start ();
$token = $_REQUEST ['token'];
if (! isset ( $token )) {
$serverName = $_SERVER ['SERVER_NAME'];
$serverPort = $_SERVER ['SERVER_PORT'];
$url = dirname ( 'http://' . $serverName . ':' . $serverPort . $_SERVER
['REQUEST_URI'] );
function getMovieAmount($movieId) {
//you can replace this function with a more sophisticated one
return 1;
}
$paymentAmount = getMovieAmount($_GET['movieId']); //$_REQUEST
['paymentAmount'];
$currencyCodeType = 'USD'; //$_REQUEST ['currencyCodeType'];
$paymentType = 'Sale'; //$_REQUEST ['paymentType'];
/* The returnURL is the location where buyers return when a
payment has been succesfully authorized.
The cancelURL is the location buyers are sent to when
they hit the
cancel button during authorization of payment during
the PayPal flow
*/
$returnURL = urlencode ( $url .
'/GetExpressCheckoutDetails.php?currencyCodeType=' . $currencyCodeType .
'&paymentType=' . $paymentType . '&paymentAmount=' . $paymentAmount );
$cancelURL = urlencode ( "$url/cancel.php?paymentType=$paymentType" );
/* Construct the parameter string that describes the PayPal payment
the varialbes were set in the web form, and the
resulting string
is stored in $nvpstr
*/
$nvpstr = "&Amt=" . $paymentAmount . "&PAYMENTACTION=" . $paymentType .
"&ReturnUrl=" . $returnURL . "&CANCELURL=" . $cancelURL . "&CURRENCYCODE=" .
$currencyCodeType;
/* Make the call to PayPal to set the Express Checkout token
If the API call succeded, then redirect the buyer to
PayPal
to begin to authorize payment. If an error occured,
show the
resulting errors
*/
$resArray = hash_call ( "SetExpressCheckout", $nvpstr );
$_SESSION ['reshash'] = $resArray;
$ack = strtoupper ( $resArray ["ACK"] );
if ($ack == "SUCCESS") {
// Redirect to paypal.com here
$token = urldecode ( $resArray ["TOKEN"] );
$payPalURL = PAYPAL_URL . $token;
header ( "Location: " . $payPalURL );
} else {
//Redirecting to APIError.php to display errors.
$location = "APIError.php";
header ( "Location: $location" );
}
} else {
/* At this point, the buyer has completed in authorizing payment
at PayPal. The script will now call PayPal with the
details
of the authorization, incuding any shipping information
of the
buyer. Remember, the authorization is not a completed
transaction
at this state - the buyer still needs an additional
step to finalize
the transaction
*/
$token = urlencode ( $_REQUEST ['token'] );
/* Build a second API request to PayPal, using the token as the
ID to get the details on the payment authorization
*/
$nvpstr = "&TOKEN=" . $token;
/* Make the API call and store the results in an array. If the
call was a success, show the authorization details, and
provide
an action to complete the payment. If failed, show the
error
*/
$resArray = hash_call ( "GetExpressCheckoutDetails", $nvpstr );
$_SESSION ['reshash'] = $resArray;
$ack = strtoupper ( $resArray ["ACK"] );
if ($ack == "SUCCESS") {
require_once "GetExpressCheckoutDetails.php";
