   Hi all I have used the Yoast method to add Twitter contact field in my user profiles. Works great.
   Link: User Contact Fields in WordPress 2.9

   But now I would like to show a Twitter user link only when the field is filled in... How can I do this?
   I use
   the_author_meta('twitter', $current_author->ID)
   to show the link, but how can I make it only show the link if the field is filled in?

   Code I use in functions.php:

   function add_twitter_contactmethod( $contactmethods ) {
   // Add Twitter
   $contactmethods['twitter'] = 'Twitter';
   // Remove Yahoo IM
   unset($contactmethods['yim']);
   return $contactmethods;
   }
   add_filter('user_contactmethods','add_twitter_contactmethod',10,1);

   get_the_author_meta returns value instead of displaying. Use trim() so if the twitter data is blank but has spaces you make sure it counts as empty.

   if(trim(get_the_author_meta('twitter', $current_author->ID) != ""){
       the_author_meta('twitter', $current_author->ID);
   }

   Ok, but lets say I want a link (with a background image of a Twitter icon)
   And it should only show if the twitter field is filled in.

   I use this now:
   

   <div class="post_twitter"><a href="<?php the_author_meta('twitter'); ?>" title="Twitter"><span>twitter</span></a></div>

   CSS:
   

   .post_twitter a {
   	width: 16px;
   	height: 16px;
   	background: url("images/site/twitter.png") no-repeat;
   }
   .post_twitter span {
   	display: none;
   }

   Could you help me a bit more?

   Same way, everything inside the if statement that will show if filled in. But I split up the PHP so its easier to manage the HTML.

   <?php if(trim(get_the_author_meta('twitter', $current_author->ID) != ""){ ?>
       <div class="post_twitter"><a href="<?php the_author_meta('twitter'); ?>" title="Twitter"><span>twitter</span></a></div>
   <?php } ?>
