How to integrate some fields into a node more efficient? in my node.tpl.php i want to display a custom field (field_cta) which is part of my page.
It is working this way, but it looks so terrible...is there a drupal command to shorten all the array-walk-trough precedure? 

if (isset($content['body']['#object']-&gt;field_cta['und'][0]['value'])){ print $content['body']['#object']-&gt;field_cta['und'][0]['value'];}


Thanks a lot!
if it's Drupal 7, I think this can works.

if(isset($content['fieldname'])):

echo render($content['fieldname']);

endif;
