[webAmeteur]

at the moment I have a text box with a number in it. I want to use this number in a SQL query to update my atabase.

How do I extract the value inside the textbox into the query?

Thanks.

I have worked out how to use the data in the textboxes, but now hereis my next problem.

When using this code

if ((isset($POST["MM_update"])) && ($POST["MM_update"] == "form2")) {
$updateSQL = sprintf("UPDATE screens SET seat_status='BOOKED' WHERE seat_number=%s", GetSQLValueString($POST['hiddenField0'], "int"),
"AND seat_number=%s", GetSQLValueString($POST['hiddenField1'], "int"));

Is it possible to update more than one row in my database using the same submit.

I am trying to get upto 10 values, GetSQLValueString($_POST['hiddenField0'], "int"), then hiddenField1, then 2 etc...

It will only update the first value in hiddenField0 though.

Regards
