Conway Module

[dmarrero]

Hello:
Conway just released a PHP page that can be used to intergrate to a customers website and they can get shipping quotes on the customers website as opposed to having to leave the customers website.

I need help creating a module that i can import into zencart so that the customer can provide this method of shipping. Here is the code for the rate quote page provided by conway.

<?php
/*
Con-way XML Sample Code for PHP - Rating interface
This code has been tested on PHP 4.3.XX and PHP 5.XX
-----------------
TODO:  
* replace the USERNAME and PASSWORD String values below 
with your Con-way username and password
* to get customer-specific discounts, replace CUSTNMBR String value
below with your Con-way customer number

NOTE:  you must have the cURL libraries installed with PHP on your server--
If you need them, see your System Administrator, who can get then at

Build XML Request

For this sample we will just hard code some dummy data.
