title: How to find by multiple criteria with Phalcon findFirst?
body: <p>I'm trying to get a video from my video database, the selection is based on a unique combination of <code>external_id</code> and <code>language_id</code> (both integers). I tried the following code, but it looks like <code>findFirst()</code> only picks up the first criterium</p>
  
  <pre><code>$video = Video::findFirst("language_id=" . $language-&gt;id . " and external_id=" . $external-&gt;id);
  </code></pre>
  
  <p>Can anybody help me how to properly use findFirst with multiple criteria?</p>
