Need PHP script: Responsive multi page form with conditional logic

[phrench]

For a loan company in Switzerland I'm generating leads by including their form via iframe on my sites.

Unfortunately when it comes to conversion optimization their form sucks donkey balls.
Additionally some of my sites already have a responsive design. Needless to say their form isn't responsive.

Since in today's meeting I was able to convince them to let me build my own forms, I'm looking for a solution that offers the following features:

• Multi page support
• Conditional logic
• Responsive or easy to implement into own design

As I want to track the funnel and do A/B tests, a hosted solution is no option.


So far I've found 2-3 interesting form scripts on Codecanyon.net, but they either lack the multi page support or the conditional logic.


What is your favorite PHP form script (beside coding it from scratch)?

Forgot to mention that it should not require a database.

I'd prefer the data to be saved in XML or CSV files.

What type of conditionals do you need?

 

[phrench]

Simple conditionals like

if this checkbox/bullet is selected, display these form elements

In the meantime I found this: Zebra_Form, a jQuery augmented PHP library for creating and validating HTML forms

Looks promising and unless something better pops up it's going to be zebra

Why wouldn't you put it in a database and just export it as a CSV? Using a CSV as a database just sounds like a royal pain in the ass.
