Authorize API

[eluser]mikeyhell[/eluser]
Had to write this for a project... It's somewhat unfinished and I had to take some things out for security, but this should be a good starting point for someone looking to integrate authorize.net

Part 1:

Code:

<?php


class Authorize
{

//****************************************************************************

   function __construct( $processXML )
   {
      $this->processXML = $processXML;
   }

//****************************************************************************

   /**

   * @param array $params An assosciative array of paramaters to pass to Authorize.net
   * @return array Array of the results from the payment gateway
   */

   function chargeCard( $params, $processor = array() )
   {
      /**
      * Configuration
      */

      $x_Login    = (string)$this->processXML->user;     // Your authorize.net login
      $x_Password = (string)$this->processXML->password; // Your authorize.net password (if Password-Required Mode is enabled)
      $x_Tran_Key = (string)$this->processXML->tranKey;  // Your authorize.net tran_key

      if( isset( $processor['user'] ) && $processor['user'] != '' )

Thanks for the code Michael.

Do you have any examples of using this class with CodeIgniter?

[eluser]mikeyhell[/eluser]
I Believe this has been replaced. Check the wiki for examples.

[eluser]Overlord[/eluser]
Didn't find anything on the wiki for Authorize(.Net), and only PayPal came up under a search of payment...

[eluser]manilodisan[/eluser]
This is good resource...thanks man.

[eluser]mikeyhell[/eluser]
Haven't found the time to do too much to it beyond my own stuff, but hopefully it will save someone some work.

[eluser]Overlord[/eluser]
So I'm going to go back with my original question (that might help others also):

"Do you have any examples of using this class with CodeIgniter?"

[eluser]manilodisan[/eluser]
I will add it to my project. I need to find something or create my own for 2checkout and I'll add them.
