Hi

I have the following php code which simply displays links on the page:

<?php
      if($_GET['id'] == "")
      {
            echo getdata("");
      }
      else
      {
            echo getdata("and link_group like '%".$_GET['id'].",%'");
      }

      function getdata($querystring)
      {
            $connection = mysql_connect('servername', 'password', '') or die (mysql_error());
            $db = mysql_select_db('database', $connection) or die (mysql_error());
            $query = "select * from link_info where archive = 0 and inactive = 0 and type = 'news' ".$querystring." order by display_date desc";
            $result = mysql_query($query) or die (mysql_error());
                  
            global $the_data;

            $the_data = '';
            while ($row = mysql_fetch_array($result))
            {
                  extract($row);
                  $new_date = date('F Y', strtotime($display_date));
                  
                  $the_data = $the_data."<div class='newsdate'>$new_date</div>";
                  $the_data = $the_data."<div class='newssubject'><a href='links/news/$file_name' title='Download $description link'><img src='images/linkicon_small.gif' alt='link' width='17' height='17' /> $description</a></div>";
                  $the_data = $the_data."<div class='clear'></div>";
            }            
            mysql_close($connection);
            
            return $the_data;
      }
?>

How do I create paging with this?  So it only displays 15 results at a time.  If they want to see the next 15, they have to click the page number at the bottom, i.e. Page 1,2,3,4.  The page number depends on how many links are returned,  so if <= 15 links are returned, it only displays page 1, if more > 15 and <= 30 it should display Page 1,2.  and so on.

Can this be done?
