openSSL API integration

dennismonsewicz · February 12, 2009

I am trying to setup an ecommerce website and my client has purchased a CC processing gateway through yourpay.com and I am trying to follow their documentation for setting up their PHP API integration but I am confused as all get out.

the example form code they give

<?php
echo"<html><head><title>PHP_FORM_MIN.php LinkPoint Sample </title></head><body><br>";

/*
<!---------------------------------------------------------------------------------
* PHP_FORM_MIN.php - A form processing example showing the minimum 
* number of possible fields for a credit card SALE transaction.
*
* This script processes form data passed in from PHP_FORM_MIN.html

	This program is based on the sample SALE_MININFO.php

	Depending on your server setup, this script may need to
	be placed in the cgi-bin directory, and the path in the
	calling file PHP_FORM_MIN.html may need to be adjusted
	accordingly.

	NOTE: older versions of PHP and in cases where the PHP.INI
	entry is NOT "register_globals = Off", form data can be
	accessed simply by using the form-field name as a varaible
	name, eg. $myorder["host"] = $host, instead of using the 
	global $_POST[] array as we do here. Passing form fields 
	as demonstrated here provides a higher level of security.

include"lphp.php";
$mylphp=new lphp;

# constants
$myorder["host"]       = "hostname";
$myorder["port"]       = "postname";
$myorder["keyfile"]    = ".PEM-file"); # Change this to the name and location of your certificate file 
$myorder["configfile"] = "store-number";        # Change this to your store number

$myorder["ordertype"]     = $_POST["ordertype"];

if ($_POST["debugging"])
	$myorder["debugging"]="true";

  # Send transaction. Use one of two possible methods  #
//	$result = $mylphp->process($myorder);       # use shared library model

# print complete server response to a table
if ($_POST["verbose"])
{
	echo "<table border=1>";

	while (list($key, $value) = each($result))
	{
		# print the returned hash 
		echo "<tr>";
		echo "<td>" . htmlspecialchars($key) . "</td>";
		echo "<td><b>" . htmlspecialchars($value) . "</b></td>";
		echo "</tr>";
	}	

	echo "</TABLE><br>\n";
}
?>

I am not understanding how all of this is supposed to work...

here is some of their instructions from their website

Build the XML string yourself and send it directly to the secure payment gateway.

This option requires a PHP version higher than 4.0.2 and cURL support to be compiled

into PHP. (This is the default setup for Red Hat® Linux® server installations.)

This option does not use the PHP module to build the XML string. You need to manage

your own XML output. This option is demonstrated in the PHP sample program

pass_xml_direct.php.

2. Use cURL (with OpenSSL) along with the lphp.php module.

Use this option with older versions of PHP or where PHP has not been compiled to

support cURL. This object accepts either hash-style input or XML.

3. Use the PHP built-in cURL methods along with the lphp.php module.

This is the easiest option to use. It requires PHP version higher than 4.0.2 and that

cURL support is compiled into PHP. (This is the default setup for Red Hat Linux server

installations.) This option accepts either hash-style input or XML.

4. Use the lphp.php module with the provided shared libraries and OpenSSL.

This option requires the provided shared libraries libspssl.so and liblphp.so to be

installed, and that you have OpenSSL libraries built with shared object support on your

web server.

This option uses the lphp.php module to accept either hash-style input or XML. It is

recommended for users with admin privileges on their server to correctly install the

shared libraries. FreeBSD 3.3 PHP users should not attempt to use the shared libraries

option. Shared libraries are not supported for FreeBSD 3.3 with PHP.

5. Build the XML stream yourself and send it through cURL or the shared libraries

provided with the PHP module.

This option requires the provided shared libraries libspssl.so and liblphp.so to be

installed, and that you have OpenSSL libraries built with shared object support on your

web server.

This option is demonstrated in the PHP sample program pass_xml_lib.php. To

determine whether PHP cURL support is installed, enter the command php -m in the

command prompt window.

If anyone can shed some light into my world, I will be greatly appreciative. I have contacted their support but its so hard to get anyone to answer back and in a timely manner. Thanks!

Where are you stuck? In the example provided the form would send the CC info to the php file which sends the order info off to the merchant and reads the result.

dennismonsewicz · February 12, 2009

When you submit the information to the PHP file..

the following displays

Status: <

Error: <

Which according to yourpay.com's support line is because the .PEM file cannot be found but the .PEM file is in the same directory as all of the rest of the files... so I am not sure what is happening

tested this in on a Linux box and everything worked perfectly...

Its the hosting company I am using!

I am getting

Status : <

Error: < this on submit? can i know how you solve this problem

He posted his solution.

Probably some sort of configuration having to do with the platform was necessary.
