You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

$f55 = mysql_query("SELECT * FROM `member_online` WHERE uId = '".$_SESSION['uId']."'");

<?php
$sql = "SELECT * FROM tabel";
if(!$resultaat = mysql_query($sql)) {
echo mysql_error().' In query: '. $sql;
}
?>

if(!$resultaat = mysql_query($sql)) {

Lees bovenstaande handleiding eens door. Daarin wordt onder andere uitgelegd hoe je SQL queries uitvoert en fouten die daarbij optreden kunt herkennen en oplossen.
Leg ook even uit hoe je het opgelost hebt. Wel zo handig voor iemand die hetzelfde probleem heeft.
