title: Wordpress $curauth conditional statement on author.php
body: <p>I am trying to display twitter &amp; facebook links on the author.php page only if these have been added to the profile in the backend.</p>
  
  <p>I can display the Twitter profile using $curauthor with this code:
  twitter); ?>">Twitter</p>
  
  <p>How do I put this in to a conditional statement so it only shows this URL if the details have been added for that user?</p>
  
  <p>Thanks!</p>
