AuthNetClass

I wanted a quick and dirty way to simply use the AuthorizeNet AIM interface to process payments. I didn't find a php routine readily available, So I wrote one.

This script takes care of all the basics - it will generate the POST request, and parse the POST results.

Below is an example of a credit card transaction:

Example:

require_once ("AuthNetClass.php");

$tp = new authNetClass("7nqsdff3z4122", //TransKey "6JSHSD5K", //Login true);

//Use the AIM manual to determine the necessary field names.

$tp->SetElement("x_card_num", "43123231111225"); //Credit Card Number

$tp->SetElement("x_exp_date", "1209"); //Expiration Date

$tp->SetElement ("x_amount", "1.03"); //Amount of trans

$tp->SetElement ("x_type", "AUTH_CAPTURE"); //We want to do an auth capture

$tp->SetElement ("x_method","CC"); //This is a CC transation

//Send to the server

$tp->DoTransaction();

//Here is my response code

print ("RV: ".$tp->GetReturnedValues("Response Code"));

We created an instance of AuthNet, passing in the login and transaction key. Both of these are obtained from AuthorizeNet Member Settings. You can also specify true for the debug, which proceeds to print out information useful for testing/debugging.

Set a few of the required elements (see AuthorizeNet's AIM documentation), and then throw in a doTransaction.

By using getReturnedValues, you get access to the values passed back from the authorizenet server.
