I've used header() a hundred times. For some reason this just gives me a blank screen. The url exists and the script gets into the conditional and exits.
This is a modification of Larry's script in chapter 16 that I get get to work because of this.
thanks very much
if (!isset($_SESSION['first_name']) || $_SESSION['user_level'] == 0 ) {
echo "Hello, I should be redirecting now...";
header('Location: https://tenthousandeyes.org/.php');
exit(); // Quit the script.
}
