When HTTP performs a redirect all POST data is lost because the browser performs a GET request.

You could convert the data to GET and send it along in the url however, this is a bad practice. It would potentially reveal secure information in the address bar with the URL.

A better option would be to use cURL to do a post to the URL via a class.

<?php

Class CurlExample
{
    protected function transmitData($data, $url)
    {
        $curl = curl_init($url);
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        curl_exec($curl);
    }
}

That is one option. You could also use Buzz\Browser a PHP extension you can use instead of cURL.

However, the best idea is to use an API. Most payment gateways have an API you can hook into in order to send them the data they are expecting.

I hope this was helpful.
