online.php

hallo iederen ik heb ergens deze script vandaan geloof hier

<?
// sessie zelf instellen
if ( isSet ( $_SESSION['user_id'] ) )
{
$iUser_id = $_SESSION['user_id'];
}
else
{
$iUser_id = 0;
}

$rQueryUsernameBepalen = mysql_query ( "SELECT id, username FROM users WHERE id = ".$iUser_id ) or die ( mysql_error() );
$aQueryUsernameBepalen = mysql_fetch_assoc ( $rQueryUsernameBepalen );
$sUsername = $aQueryUsernameBepalen['username'];

/* #### INSTELBARE VARIABELEN #### */

$sIpadres = $_SERVER['REMOTE_ADDR'];
$sHuidigePagina = $_SERVER['HTTP_REFERER'];
$sTime = time()+180; // is 3 minuten



$sQuerySelectOnline = "SELECT count(*) FROM online WHERE ip = '".$_SERVER['REMOTE_ADDR']."'";

$rQuerySelectOnline = mysql_query ( $sQuerySelectOnline );

$aQuerySelectOnline = mysql_result ( $rQuerySelectOnline,0 );

// wanneer het ipadres er nog niet instaat

if ( $aQuerySelectOnline == 0 )
{
$rQueryInsert = mysql_query ( "INSERT
INTO online ( ip, locatie, tijd, user_id, username )
VALUES ('" . mysql_real_escape_string($sIpadres) . "','" . mysql_real_escape_string($sHuidigePagina) . "','" . mysql_real_escape_string($sTime) . "', '" . mysql_real_escape_string($iUser_id) . "', '" . mysql_real_escape_string($sUsername) . "' ) " ) or die ( mysql_error() );
}
else // het ipadres staat er dus wel in
{
$rQueryUpdate = mysql_query ( "UPDATE online
SET locatie='" . mysql_real_escape_string($_SERVER['HTTP_REFERER']) . "', tijd = '" . mysql_real_escape_string($sTime) . "', user_id = '" . mysql_real_escape_string($iUser_id) . "', username = '" . mysql_real_escape_string($sUsername) . "'
WHERE ip = '" . mysql_real_escape_string($_SERVER['REMOTE_ADDR'])."'" ) or die ( mysql_error());
}


$iHuidigeTijd = time();

mysql_query("DELETE FROM online WHERE tijd < $iHuidigeTijd");

$sQueryGastenOnline = "SELECT * FROM online WHERE user_id = 0";
$rQueryGastenOnline = mysql_query ( $sQueryGastenOnline );
$iAantalGastenOnline = mysql_num_rows ( $rQueryGastenOnline );

$sQueryLedenOnline = "SELECT * FROM online WHERE user_id <> 0";
$rQueryLedenOnline = mysql_query ( $sQueryLedenOnline );
$iAantalLedenOnline = mysql_num_rows ( $rQueryLedenOnline );


echo "Gasten: ".$iAantalGastenOnline."<br />";
echo "Leden: ".$iAantalLedenOnline."<br />";

while ( $aQueryLedenOnline = mysql_fetch_assoc ( $rQueryLedenOnline ) )
{
echo '<a href=#>'.$aQueryLedenOnline['username'].'</a>,';
}
?>


maar nu krijg ik deze fout melding
