Checkout.com Payment gateway integration

I would create a helper and it would look something like:

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

function checkout()
{
   require_once('/server/path/to/assets/checkout/release/v1.0/autoload.php');
} 


In an assets folder, create a folder called checkout and put their php library into it.

Then you can use it by loading

PHP Code:

$this->load->helper('checkout'); 


Then all their functions are available for you to use in your controller.

Hope that helps,

Paul.
