I need to build a questionnaire embedded in a Wordpress page. The questionnaire will be a multi-part form (20 consecutive screens with questions followed by a results page). The results page will be created by scoring the answers and doing some basic calculations and normalization. Web search returned me Ninja Forms and Formidable Pro as feasible options (i.e multi-part forms with PHP). Does anybody have an experience with these or any other form builders that work with WP and allow PHP scripting and multi-part forms creation? Any feedback? Recommendations? It's been really long time since I've done PHP coding, so I am going to hire a developer to do this job but want to do some due diligence to verify the approach and technology. Thanks!
I have used gravity forms with nice results in the past. I am not sure about the scoring part but they do have a quiz addon that you might be able to use for that http://www.gravityforms.com/add-ons/quiz/
Thanks Markus, I'll try Gravity Forms. If they have quiz add-on they must have scoring to display results.
