title: Creating a widget from the "Popular member" widget and want to append data from a custom field
body: <p>I am creating a widget to show most active viewers but want to also fetch a custom field by alias. I have the below in my .tpl:</p>
  
  <pre><code>&lt;ul&gt;
  &lt;?php foreach( $this-&gt;paginator as $mam_user ): ?&gt;
      &lt;div&gt;
       &lt;?php echo $this-&gt;htmlLink($mam_user-&gt;getHref(), $this-&gt;itemPhoto($mam_user, 'thumb.icon'), array('class' =&gt; 'popularmembers_thumb')) ?&gt;
           &lt;h3&gt;
             &lt;?php echo $this-&gt;htmlLink($mam_user-&gt;getHref(), $mam_user-&gt;getTitle()) ?&gt;
           &lt;/h3&gt;
           &lt;?php
              // Fetches Fields from database by Alias
              $tagline = Engine_Api::_()-&gt;fields()-&gt;getFieldsValuesByAlias();
              echo $this-&gt;$mam_user-&gt;$tagline['tagline'];
           ?&gt;
      &lt;/div&gt;
  &lt;?php endforeach; ?&gt;
  </code></pre>
  
  <p></p>
  
  <p>I controller file is the same as that of the "Popular members" untouched.. but something seem not working here. I guess i'm doing something wrongly here.
  Any help pls..; and thanks in advance.</p>
