Hi There,

I have a form with various checkboxes, they got names i have from a db
to identify them.
Now I would like to check what has been posted by the form. For that I
would like to read all the field names from the db and check if they
have been set something like this:

$result = mysql_query("SELECT * FROM specialty");
while($row = mysql_fetch_array($result)) {
if (isset($_POST[$row['name']])) {
var_dump($POST);
session_unset();
}

But this doesn't seem to work the way I expected it to? I.e. I would
liek to check if $_POST['MyCheckbox'] is set now but MyCheckbox is a
name from the database. How do I do this best, the easiest way?

Thanks,
Ron
