title: How to get Post Data from Magento's Onepage Checkout?
body: <p>in order to add a customers comment field in the Magento Checkout, I added a text field in the appropriate template file and added the comment to the order using an observer like this:</p>
  
  <pre><code>        $comment = strip_tags(Mage::app()-&gt;getRequest()-&gt;getParam('cpOrderComment'));  
  
          if(!empty($comment)){  
             $observer-&gt;getEvent()-&gt;getOrder()-&gt;setCustomerNote($_comments);              
          } 
  </code></pre>
  
  <p>This worked perfectly using the OnestepCheckout extension, however it does not work with Magento's Onepage Checkout. The "getParam('cpOrderComment')" is always empty and now I not sure how to get the value of my text field.</p>
  
  <p>Any ideas would be greatly appreciated!</p>
