Preload Form or POST/GET

[Jakec11]

I've been building forms in Campaign and have hit a snag I'm looking for the best solution for. I want to host a form directly on my site (rather than link off or iFrame). I don't want to have to do anything too complex for my team to keep up or modify (APIs). In the past/on other systems, I've been able to create a simple form with a POST or GET to a program hosted form that auto populates (and can either act as a confirmation page or auto submit via script). Primarily, I want to send form data from a website to campaign - how can I do it?

The Neolane documentation seemed to suggest that preloading data with specific fields, then creating an html string would autoload string data into the form (such as email). But none of my tests are working.
