<?php
/********************************************
* ReviewOrder.php
*
* This file is called after the user clicks on a button during
* the checkout process to use PayPal's Express Checkout. The
* user logs in to their PayPal account.
*
* This file is called twice.
*
* On the first pass, the code executes the if statement:
*
* if (! isset ($token))
*
* The code collects transaction parameters from the form
* displayed by SetExpressCheckout.html then constructs and
* sends a SetExpressCheckout request string to the PayPal
* server. The paymentType variable becomes the PAYMENTACTION
* parameter of the request string. The RETURNURL parameter
* is set to this file; this is how ReviewOrder.php is called
* twice.
*
* On the second pass, the code executes the else statement.
*
* On the first pass, the buyer completed the authorization in
* their PayPal account; now the code gets the payer details
* by sending a GetExpressCheckoutDetails request to the PayPal
* server. Then the code calls GetExpressCheckoutDetails.php.
*
* Note: Be sure to check the value of PAYPAL_URL. The buyer is
* sent to this URL to authorize payment with their PayPal
* account. For testing purposes, this should be set to the
* PayPal sandbox.
*
* Called by SetExpressCheckout.html.
*
* Calls GetExpressCheckoutDetails.php, CallerService.php,
* and APIError.php.
