   ?>

Answer 1

If I understand correctly, you're parsing the article text to get the image link and the display it somewhere in your view.

Check before echo

<?php
if(isset($imagename) && $imagename != ""){
   echo $html->link( $html->image($imagename,array('height'=>'250px','width'=>'280px')),array('action' => 'view',$article['Article']['id']),array('escape' => false));
}
?>
