Example Payment Module (authorize.net)

[NixBill]

This is an example of how to create payment modules and to return the correct values.
The clients credit card information is stored encrypted, but when it gets to the payment module it comes unencrypted.

PHP Code:

<?php
class authorize_net{
    var $ModuleId;
    var $Result = array();
    function authorize_net($id=false){
        $this->ModuleId = $id;

                            array('formtype' => 'text', 'description' => 'Account Id', 'name' => 'auth_net_login_id', 'value' => ''),
                            array('formtype' => 'text', 'description' => 'Trans Key', 'name' => 'auth_net_tran_key', 'value' => ''),
