I need a reference number (or PO number) to be included on the checkout and sent with the customer information for the transaction. Magento, version 1.9.1, does not include this as an option out of the box. In order for this to be accomplished, I will need a custom text box for the user on the checkout page as well as adding the data to the request to send to the gateway.
I am very hesitant to edit Magento "core" files. The file that prepares the request for Authorize.net is /app/code/core/Mage/Paygate/Model/Authorizenet.php
Beginning at line 1134, here is the code that preps the request:
/**
* Prepare request to gateway
*
* @link http://www.authorize.net/support/AIM_guide.pdf
* @param Mage_Payment_Model_Info $payment
* @return Mage_Paygate_Model_Authorizenet_Request
*/
protected function _buildRequest(Varien_Object $payment)
{
$order = $payment->getOrder();
$this->setStore($order->getStoreId());
$request = $this->_getRequest()
->setXType($payment->getAnetTransType())
->setXMethod(self::REQUEST_METHOD_CC);
if ($order && $order->getIncrementId()) {
$request->setXInvoiceNum($order->getIncrementId());
}
if($payment->getAmount()){
$request->setXAmount($payment->getAmount(),2);
$request->setXCurrencyCode($order->getBaseCurrencyCode());
}
switch ($payment->getAnetTransType()) {
case self::REQUEST_TYPE_AUTH_CAPTURE:
$request->setXAllowPartialAuth($this->getConfigData('allow_partial_authorization') ? 'True' : 'False');
if ($payment->getAdditionalInformation($this->_splitTenderIdKey)) {
$request->setXSplitTenderId($payment->getAdditionalInformation($this->_splitTenderIdKey));
}
break;
case self::REQUEST_TYPE_AUTH_ONLY:
$request->setXAllowPartialAuth($this->getConfigData('allow_partial_authorization') ? 'True' : 'False');

}I also need to figure out how to add a custom "Purchase Order" or "Reference ID" on the cart page. I am using the "Onepage" checkout option and I don't know which files I would need to add the text field. I've never added custom fields to Magento forms so I would appreciate help with that as well.
The front-end code for the onepage checkout is located in app/design/frontend/base/default/template/checkout/onepage/.
Thanks in advance!
