Below you can find sample code for Payments page in PHP. You should also use this Testing Guide, which also contains test card details.
The sample code below requires the PHP XML API.
Settings file (worldnet_account.inc):
<?php # These values are used to identify and validate the account that you are using. They are mandatory. $gateway = ''; # This is the Worldnet payments gateway that you should use, assigned to the site by Worldnet. $terminalId = ''; # This is the Terminal ID assigned to the site by Worldnet. $currency = ''; # This is the 3 digit ISO currency code for the above Terminal ID. $secret = ''; # This shared secret is used when generating the hash validation strings. # It must be set exactly as it is in the Worldnet Selfcare system. $testAccount = true; # These are used only in the case where the response hash is incorrect, which should # never happen in the live environment unless someone is attempting fraud. $adminEmail = ''; $adminPhone = ''; ?>
