Problema con paginacion de resultados [PHP y mysql]
#1
Estoy probando paginar las entradas de un foro probablemente sea un error de sintaxis o le pifié en algo Lengua ojalá alguien me heche un cable con esto...

foro.php
Código:
<html>
<!--La tabla con la consulta a la base de datos del foro -->
<table border="1" cellpadding="2" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="100%" id="AutoNumber1">
<?
$sql = "SELECT * FROM foro WHERE foro = '".$foro."' ORDER BY id DESC LIMIT 5";
$res=mysql_query($sql,$db);
while ($row=mysql_fetch_array($res)){
$rows = 1;
?><tr>
    <td width="82%" colspan="2"><font face="Verdana" size="2"><b><? echo $row["autor"]; ?></b><br />
    <? echo htmlentities($row["mensaje"]); ?><br />
    </font><b><font face="Verdana" size="2">
    <a href="?foro=<? echo $row["id"]; ?>"><?
    echo mysql_result(mysql_query("SELECT COUNT(id) FROM foro WHERE foro = '".$row["id"]."'",$db));
?> [Leer mas]</a></font></b></td>
  </tr><?
}
if($rows == ''){ ?><tr>
    <td width="82%" colspan="2"><font face="Verdana" size="2">No hay mensajes en este foro</font></td>
  </tr><?
}
?><tr>
    <td width="82%" colspan="2"><font face="Verdana" size="2"><b><a href="?escribir=<?
echo $foro;
?>">Escribir mensaje</a><?
$arriba = @mysql_result(mysql_query("SELECT foro FROM foro WHERE id = '".$foro."'",$db));
if($arriba != '')echo ' | <a href="?foro='.$arriba.'">Volver</a>';
else echo ' | <a href="?foro=">Volver</a>';
?></font></b></td>
  </tr>
</table>

<!--script de paginacion-->
<?

require_once('paginator.class.php');
$pages= new Paginator;
$pages->items_total = "SELECT COUNT(*) FROM foro WHERE foro='0'"; // cambiamos X por el total
$pages->mid_range = 7;
$pages->paginate();
echo $pages->display_pages();
?>

</html>

paginator.class.php (lo agrego aunque probablemente el error está arriba)
