A mostly Out of the Box Quiz with ExpressionEngine

I'm working for an agency here in Toronto and one of the sites that I'm currently working on has a matchmaker quiz. There are four questions each with three possible answers and when the user clicks submit they are taken to a results page which will list a recommended product for them to purchase. This sounds simple enough on the surface but I was struggling with the best approach to this for a while. In the end though it was actually quite simple to achieve and only required one additional add-on.

This sounds simple enough on the surface but I was struggling with the best approach to this for a while. In the end though it was actually quite simple to achieve and only required one additional add-on.

I approached Carl Crawley on skype about what I thought would be a good way to do this, but his suggestion was much simpler and most of what I'm putting here is a result of my conversation with him.

First up, build a channel called quiz results. with five fields. The first for field types need to be drop downs - I called mine {question-one}, {question-two}, {question-three} and {question-four} and populated with the answers a, b, c each on a new line. The last field is a relationship field which will be the product that the results link to, I called this {question-result}. Now start the data entry creating entries for each possible combination of answers.

Next build a basic form with radio buttons for the answer. You'll also need some way to get the $POST data into the quiz results page to pull up the correct answer. I thought about using strait php, but didn't want to enable php on my templates so looked to devot:ee for an add-on and found a few. The one that I chose looked best and is dead simple to use: EvoPost.

Next you need to create a new template called evopost (or whatever you want it to be) and set the action="" to point to that template like this action="{site_url}/template_group/evopost" and then in the evopost template you add the following code where you prefix the name="" value of each field with ep_ so if your field is name="old" then your post data would be {ep_old}:

This then redirects to the results template where Where your channel entries tag then pulls this information from the url structure like this

And there you have dynamically pulled answers based on a quiz - of course with four questions - each with three answers, there's a fair amount of data entry to ensure that you have results for every possible combination.
