This is very unlikely to be true.  This "page" is likely going to be the
result of a GET request rather than a POST.

But this code is the result of a POST request -- specifically the result
of submitting the form shown above.  In other words it's here where you
need to look at $_POST["uF"].  If you need to set a session variable,
it's here you would do it.

That happens as a result of submitting the form.  You don't need to do
anything with session variables at all.
