php question

message from wikstov on 21 Jul 2004

i'm rather new to this, so please don't shoot me for asking something all too
obvious

what is wrong with this code?

session_start();

$aantal=$_SESSION['aantal'];
echo $aantal;

while ($i<=$aantal){
if (isset($_POST['inschrijvingID[$i]']))$recs[]="inschrijvingID[$i]";
$i++;
}
if (is_array($recs)){
echo "OK";
if (count($recs)>1){
$where=join($recs,",");
$sql="UPDATE mytable SET field=value WHERE field IN ($where)";
}
i'd at least expect it to display "OK", but it doesn't
thanks to all of you who can help me out

What's the value of $aantal? Does it display anything?

$i is not initialized.

$recs is not initialized.

While the above may not be the reasons for your problem, I _strongly_
recommend to set error_reporting to E_ALL in your php.ini first and fix
the reasons for the notices that will show up then.
