This is my implementation of a class for using PayflowPro transactions.
I programmed this so that I had an easy way of integrating the
Verisign stuff into some existing sites.
All information used to base this class on was taken directly out of
the Payflow Pro Developer?s Guide (Release Date: November 9, 2000).
Tender types that are supported by this class are:
Credit Cards (Purchase, Business, Corporate)
Tender types to have support added soon:
Electronic Checks
ACH Checks
Functions that you will use include:
pfp_class($user,$pwd,$test=1,$port=443,$time='45',$prox='',$proxp='',$proxl='',$proxw='')
The class constructor. This is called whenever you need to instantiate a
class object.
$user your Verisign merchant ID
$pwd your Verisign password
$test set this to 1 if you are only testing
$port the port of the processing server
$time the timeout for the transaction
$prox your proxy server (if needed)
$proxp your proxy port
$proxl your proxy login
$proxw your proxy password
CustomerDetails($name,$street,$city,$state,$zip,$phone='',$email='',$drvlic='')
Use this to set information about the purchasing party. The parameters
should not need more explanation than saying $drvlic is for the
driver's license number of the customer.
UseCreditCard($acct,$amt,$expdate,$trxtype,$commcard='P')
This is the function to call to make a credit card transaction.
$acct Credit card number
$amt Amount of transaction
$expdate Expiration date of the card (MMYY)
$trxtype Transaction type (See TRXTYPE in Payflow Pro Developer's Guide)
$commcard Card type (See COMMCARD in Payflow Pro Developer's Guide)
sets:
$respmesg The response string given from the transaction (error
messages, feedback, etc.)
$authcode The authorization code issued from the bank
$pnref Payment Network Reference ID for transaction
$avsaddr String telling of matching state of customer's street
address from the Address Verification Service
$avszip String telling of matching state of customer's zip code
address from the Address Verification Service
returns:
1 on accepted transaction
0 on declined transaction
-1 on communication error
