    Hi guys,

    I need a way to not display something if the meta field is empty for the user.

    Here’s what I’m doing.

    I’ve created a few custom fields, and am displaying them in their users pages. I need away to not display icons for social networks if their not filled. here my code.

    <?php
  $key = 'facebook';
  $single = true;
  $user_last = get_user_meta( $user_id, $key, $single );
 echo '<a href="' . $facebook . '"><img src="/img/facebook.png" width="43" height="42" /></a>   ';
?>

    <?php
   $key = 'facebook';
   $single = true;
   $user_last = get_user_meta( $user_id, $key, $single );
   if (!empty($user_last)) :
      echo '<a href="' . $facebook . '"><img src="/img/facebook.png" width="43" height="42" /></a>   ';
   endif; ?>

    The only other (cosmetic) modification I would consider is not echoing out that HTML fragment with PHP, but instead outputting it like this:

    <?php
   $key = 'facebook';
   $single = true;
   $user_last = get_user_meta( $user_id, $key, $single );
   if (!empty($user_last)) : ?>
      <a href="<?php echo $facebook; ?>"><img src="/img/facebook.png" width="43" height="42" /></a>
   <?php endif; ?>

    In this case it may not look like much of an improvement, but in general, creating HTML parts with PHP makes your code less readable.
