Question

I`m looking to create a form where upon submission, all the values from the form are added up together.

At the same time I would define a session within the controller so later the added up values can be written into the DB.

views/quiz/new.html.erb :

<% form_tag do %>
        <%= form_tag(:controller => "quiz", :action => "new", :method => "post") %>
        <div id="container">
        <p class="question">The glass is...</p>
        <ul>
            <%= radio_button_tag :value, '2' %>
            <li>Half full.</li><br>
            <%= radio_button_tag :value, '1' %>
            <li>Half empty.</li><br>
            <%= radio_button_tag :value, '3' %>
            <li>What glass?</li><br>
        </ul>


<p class="question">When does the narwhal bacon?</p>
            <ul>
                <%= radio_button_tag :value, '2' %>
                <li>Tomorrow.</li><br>
                <%= radio_button_tag :value, '1' %>
                <li>Midnight.</li><br>
                <%= radio_button_tag :value, '3' %>
                <li>Mmm, I love bacon.</li><br>
            </ul>

         <p class="right">
            <%= submit_tag "Submit Answers", :class => "submit_button" %>
        </p>
        </div>
<% end %>

Don`t quite know how the controller would look like for this though.

How would I add the selected values together upon submission?

Answer 1

sum = 0
params.each_pair do |key, value|
  sum += value.to_i
end

# sum now has your added values
