// vérifier si l'utilisateur a choisit de se déconnecter
if ( $action == "quitter" ) {
session_unset();
session_destroy();
}
}
// vérifier si les variables sont affectés.
if(!isset($_SESSION["l_user"]) || !isset($_SESSION["l_pwd"])) {
unset($_SESSION["l_user"]);
unset($_SESSION["l_pwd"]);
header("Location: login.php");

}

}

// manitenant se loguer sur SAP system
