I want to build a recommended list of products based on a questionnaire that a visitor completes. For example, if my questionnaire is for cars, I will ask them if they like small cars, medium sized cars, or large sized cars. If they select medium sized cars, I will provide a picture and product details for a 4-Runner, Chevy Equinox, etc.
How do I use a database, link it to a questionnaire that a visitor fills out on my website, then provide specific results from my database?
Thanks for the help, and let me know how I can explain more clearly.
