As a side comment, should '
"Statu" => 1
' not be '
"Status" => 1
'?
Your problem lies in the fact that you are closing your session with:
unset($_SESSION['FBRLH_state']);
When you want to redirect, you are checking if the session is set using:
if (!isset($_SESSION['loginer'])) {
which will be
false
as you have closed your session, meaning the page will not re-direct. You can check it using:
if (!isset($_SESSION['loginer'])) {
header("location: product.php");
} else {
echo "I have closed the session, there are no session for me";
}
