 * I have defined a custom post type, and with it, a number of custom fields that
   are displayed. All is well, except, I cannot hide fields, when they are not filled
   in. This is how I tried to do it:
 *     ```
       function the_brb_meta() {
           global $id;
   
           if ( $keys = get_post_custom_keys() ) {
               foreach ( $keys as $key ) {
                   $keyt = trim($key);
                   if ( '_' == $keyt{0} )
                       continue;
                       echo "<ul class=\"post-meta\">\n";
                          $values = array_map('trim', get_post_custom_values($key));
                       $value = implode($values,', ');
                       if(!empty($key)) {
                              echo "<li><span class=\"post-meta-key\">$key:</span> $value</li>\n";
                           echo "</ul>\n";
                           }
                   }
           }
       }
       ```
   
 * but the empty fields still show up. What is wrong with my code’s logic?
 * Any help appreciated.

 * it seems that the opening `<ul ...>` is outside your conditional check;
 * also, i would assume that you would need to check the $value, and not the $key.

   Thanks, mate!
