Put some

 tags around it and I'll have a look at it, code means nothing to me without syntax highlighting.

Well, first, [php] tags help.

<html>
<body>
<?php
$data="guestbook.txt";
if($file=fopen($data,"r"))
{
while(!feof($file))
{
$contents_old.=fgets($file,255);
}
fclose($file);
}

$ar_row=explode("\n",$contents_old);

$recperpage=3;
$row_first=1;
$row_last=count($ar_row)-1;
if (empty($row_start)){ $row_start=$row_first; }
$row_end=$row_start+$recperpage-1;
if ($row_end>$row_last){ $row_end=$row_last; }

if ($row_last>$recperpage){
echo "Page : ";
for ($p=1; $p<=ceil($row_last / $recperpage); $p++){
if ($p>1){ $start=((($p-1)*$recperpage)+1);

} else { $start=1; }
if ($p==ceil($row_start/$recperpage)){ $tdcol="#cccccc"; } else { $tdcol="#ffffff"; }
echo "<font style=\"background-color:$tdcol\">[<a href=\"$PHP_SELF?row_start=$start\">$p</a>]</font> ";
}
} echo "<table bgcolor=#EEEEEE border=1 cellspacing=0 cellpadding=5 style=\"border-collapse:collapse\" bordercolor=#999999>\n";
for ($r=$row_start; $r<=$row_end; $r++){
$ar_field=explode("\t",$ar_row[$r]);
$tanggal=$ar_field[0];
$name=$ar_field[1];
$description=$ar_field[2];
echo "<tr><td rowspan=3>$r <td><small>$tanggal<td><small>$name</tr>";
echo "<tr><td bgcolor=#FFFFFF colspan=2>";
echo "</tr>";
echo "<tr><td bgcolor=#FFFFFF colspan=2>$description</tr>";
}
echo "</table>";

?>
</body>
</html>

The other things is:
[-] $contents_old isn't instantiated before you add on to it.

so just instantiaitng the $contents_old would solve the problem??? coz i dont think that the problem is coz of that!!

still looking for solution to the problem!

I don't know. You didn't say you got an error, so there isn't anything to debug unless we can see it.

if u try to run te file against the .txt file i have provided, u will see that the pagination is done and pages are divided. But the contents of first page are the ones only shown...even if i click on link for page 2, nothing happens and the page 1 link remains higlighted and the contents dont change.....so thts the error in my code...something sumwhere is wrong and the page isnt working as it should.....
hope i have been able to explain it in the right way...

cheers
