Logic gate sequence
Development and Programming
Hi, I’m new to expression engine and was just wondering if something is theoretically possible and how it might be achieved.
A potential project requires that we ask users a series of questions and pending the outcome of those questions generate pdf “advice” sheet. The really tricky thing is that depending upon the answer of each question, a different question will be next in the sequence of questions eg.
Are you a dog or a cat?
If answer = cat goto: How loud do you meow?
If answer = dog goto: How loud do you woof?
and so on an so on…
There would be a great many of these questions, with each one being illustrated with graphics and probably loaded with AJAX so as not to have to reload the page constantly.
I need a way of building this so that it is possible to keep easy track of the relations and outcomes between all these questions and so that it is flexible enough to introduce new questions and outcomes.
Is there some kind of E module that could do this or am I firmly in the realm of custom built stuff?
Thanks for your time..
Try to use something from http://devot-ee.com/search/results/search&keywords=question&channel=addons/ maybe http://devot-ee.com/add-ons/4-eequiz/
Why not just do the entire thing in JS? Or rather, a combo of JS and channel output if you needed it. Though JS might not be the best choice if you had to actually save these results to a DB.
I’m thinking you won’t be able to pull this off without a little bit of custom work though.
Thanks for both your replies - @MaxStoun, I did look through the devot-ee addons including 4-eequiz but didn’t really find something that quite matched the bill.
@John Fuller, I would unfortunately need to save the results in a database and so I think php and mysql is probably the way forward - I think you might be right about the need for custom work though!
It’s funny as it seems like a fairly straightforward requirement in some ways and yet I’ve not found any mention of anything similar anywhere on the web :(
I bet you can use SafeCracker for this.
Hi Rob, thanks for your reply. Forgive my ignorance - I’m new to Expression Engine - I had a look at Safe Cracker but I’m not really sure what it does?! What is a SAEF and how how Safe Cracker achieve what I’m looking for?
Once again apologies for asking what are probably obvious question…
Rob, I just noticed that you’re a lead developer on Safe Cracker - no one better to answer question than you I guess! 😊
I am the former lead developer, SafeCracker is now owned by EllisLab. SafeCracker allows you to create/edit channel entries on the front end of your site. Channel entries are the core content storage in ExpressionEngine. So for your project, you could store the user’s answer to each question, and then use template conditionals based on their answer to display the appropriate followup question.
