Yes I got that bit. But if the user goes straight to the page he jumps in
and the password entered and the password processed are identical null
values.
What I mean is in this example
$_POST['user_try'] will be empty if the user has typed in the page name of
the processing page directly. I am unsure how empty because the checking for
($_POST['user_try'] == "") was not enought to trap it, it appears there is
some kind of null that is not recognised as being "". However when I echoed
it to check there was nothing there.
I have been playing with isset but cant cant get the syntax.
if (isset($_POST['user_try'])){
lots of code goes here to kick off the page
after which then i can close the if statement
}
Header("Location: whatever.php");
exit;
.... But I am still missing something, greatfull for any help
