title: POST in a form Jquery select2
body: <p>So I am using the Select2 plugin, and am having trouble posting multiple options in a form. I am able to select multiple options but can only pass one through:</p>
  
  <pre><code>&lt;form&gt;
    &lt;select multiple name="message-from-select" id="message-from-select" class="select2"&gt;
        &lt;option value="janedoen@example.com"&gt;janedoen@example.com&lt;/option&gt;
        &lt;option value="antonius@example.com" selected="selected"&gt;antonius@example.com&lt;/option&gt;
        &lt;option value="michael@example.com" selected="selected"&gt;michael@example.com&lt;/option&gt;
        &lt;option value="bayjack@example.com"&gt;bayjack@example.com&lt;/option&gt;
        &lt;option value="stacy@example.com"&gt;stacy@example.com&lt;/option&gt;
    &lt;/select&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>On my PHP page, when I var_dump after selecting multiple options:</p>
  
  <pre><code>var_dump($_POST['message-from-select']);
  </code></pre>
  
  <p>I only get one string coming through, i.e.:</p>
  
  <pre><code>string 'michael@example.com' (length=19)
  </code></pre>
  
  <p>Do I need to go to a hidden input format? </p>
