title: Get values of dynamic fields and radio button
body: <p>can you give ideas or suggestions about this problem.<br>
  im creating four radio buttons per question(a multiple choice question basically)and they are generated dynamically. if i created 3 questions that are multiple choice, 3 multiple choices will be displayed in my questionnaire. 
  if 3 multiple choice questions exist, 3 questions x 4 radio buttons = 12 radio buttons.  this means i have a 3 set radio group consisting of four radio buttons.  my problem, how can i get the values selected in the 3 sets of radio group?</p>
  
  <pre><code>php code:
            echo "&lt;li&gt;&lt;input type='radio' name='radio' value='a' class='answer multiple'/&gt;choice&lt;/li&gt;";
            echo "&lt;li&gt;&lt;input type='radio' name='radio' value='b' class='answer multiple'/&gt;choice&lt;/li&gt;";
            echo "&lt;li&gt;&lt;input type='radio' name='radio' value='c' class='answer multiple'/&gt;choice&lt;/li&gt;";
            echo "&lt;li&gt;&lt;input type='radio' name='radio' value='d' class='answer multiple'/&gt;choice&lt;/li&gt;";
  </code></pre>
