In my file is error.
The list 5-th last added sites www is show in wrong order.
If i add more than 5 url, than i can't see next url's(unless, in $num_new_sites=5; i enlarge number for something else).
I paste here my function, if everything is all right, then i please someone, to send me two files(php.directory.inc & dir_manager.php) on my mail mailto:[email protected] in subject please write"WROX",cause i may mistake it with spam.

function list_sites($mode='top', $category_id='') {
   global $directory_tablename, $root_category_id, $PHP_SELF, $num_top_sites, $num_new_sites;
   if(!$link_id) $link_id = db_connect($default_dbname);
   if($mode=='top') {
      $order_by_str = 'ORDER BY hit DESC';
      $limit_str = "LIMIT $num_top_sites";
   }
   else {
      $order_by_str = 'ORDER BY registerdate DESC';
      $limit_str = "LIMIT $num_new_sites";
   }
   if($category_id == $root_category_id) $category_str = '1';
   else $category_str = "category_id LIKE '$category_id%'";
   $query = "SELECT url_id, title, url FROM $directory_tablename WHERE $category_str AND approved = 1 $order_by_str $limit_str";
   $result = mysql_query($query);
   if(!$result) echo sql_error();
   if(mysql_num_rows($result) > 0) {
      if($mode=='top') echo "<STRONG>$num_top_sites NAJLEPSZYCH!</STRONG><BR>";
      else if($mode=='new') echo "<STRONG>$num_new_sites NOWYCH!</STRONG><BR>";
   }
   $i = 1;
   while($query_data = mysql_fetch_array($result)) {
      $url_id = $query_data["url_id"];
      $url = "http://" . $query_data["url"];
      $title = $query_data["title"];
      echo "<STRONG> - <A HREF=\"$PHP_SELF?action=go_url&url=$url&url_id=$ur l_id\">$i. $title</A></STRONG><BR>\n";
      $i++;
   }
}

I think i have answer for my own question.
I don't know is this good idea, but it works.
In Function List_sites i change:"order by registerdate DESC" on "order by url_id DESC".
Every next url_id added is increment, so it works ok.:)
