Creating a Form Options Train to results
I’m not sure I'm saying it right: what I want to do is build a form where if a user chooses option A, then he is presented with Options 1 and 2, but if he chooses option B, he is presented with options 3 & 4... This would be like a funnel leading to a final result after several choices. I wonder if this can be done in PHP alone, or needs MySql? Are there any features in DA or WA that would help me accomplish this objective?
What is this selection process called in code speak? Any tutorials or recommendations or examples ?
