This is a follow up post to my initial Adding the Authorize.net PHP SDK to CodeIgniter 1.7. Now that CI 2.0 is out the plugins are long gone.

So after a couple of minuted fiddling with this, I managed to get the Authorize.net API working as a library in CI

Here is what you need to do :

• Step 1 – You need to download the PHP SDK from Authorize.net, you can get it here
• Step 2 – Copy the AuthorizeNet.php file and the lib folder into your copy of CI’s application/libraries folder
• Step 3 – Rename the file AuthorizeNet.php to Authorizenet.php
• Step 4- Add this to code to Authorizenet.php
  

//AuthorizeNetAIM for using AIM - replace with your preferred method
class Authorizenet extends AuthorizeNetAIM         
{
}

Now you only need to call your new library like so

$this->load->library('authorizenet');

And to use it

$this->authorizenet->setFields(
array(
'amount' => '10.00',
'card_num' => '6011000000000012',
'exp_date' => '04/17',
'first_name' => 'John',
'last_name' => 'Doe',
'address' => '123 Main Street',
'city' => 'Boston',
'state' => 'MA',
'country' => 'USA',
'zip' => '02142',
'email' => 'some@email.com',
'card_code' => '782',
)
);
$this->authorizenet->authorizeAndCapture();

Of course don’t forget to set your global variables that Authorize.net requires
You can see the included example in the SDK or the my previous post
