title: How do I pass a querystring parameter to a link in an article?
body: <p>We have some banner ads linking to an article in Joomla and they are passing a reference code in the URL, like this:</p>
  <pre><code>index.php?option=com_content&amp;view=article&amp;id=378&amp;Itemid=249&amp;ReferenceCode=WB6074
  </code></pre>
  <p>Inside the article, we're linking to a signup form on another web site and we need to pass the reference code in that URL's querystring.</p>
  <p>How do I do this?</p>
  <p>Is there a way to embed PHP in an article?  If so, then I could just use <code>$_GET[&quot;ReferenceCode&quot;]</code> to stick that parameter in the URL.</p>
