title: jquery chosen plugin - get data using php
body: <p>I'm using <strong>Multiple Select with Groups</strong> and <strong>Multiple Select</strong> from <a href="http://harvesthq.github.com/chosen/" rel="nofollow noreferrer">http://harvesthq.github.com/chosen/</a></p>
  
  <p>Does anyone know how to get the values of the submitted data using php?</p>
  
  <p><code>$_POST['countries'];</code> does not work and only returns one of the selected items (not an array)</p>
  
  <p>And here is the select tag name/id etc</p>
  
  <pre><code> &lt;select name="countries" multiple="multiple" class="chzn-select" id="countries" tabindex="6" data-placeholder="Countries"&gt;
  </code></pre>
  
  <p>PS. I already checked <a href="https://stackoverflow.com/questions/10521315/chosen-jquery-plugin-getting-selected-values">Chosen Jquery Plugin - getting selected values</a> but can't figure out what to do except for getting the value. Is there a straight forward method without using events to update a hidden field and submit data?</p>
