   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.
