    $login =$_POST['login'];
    $password =$_POST['password'];
    $user = Users::where('name', $login)->where('password', md5($password))->first();
    if(isset($user) && !empty($user) ){
        $_SESSION["user"] = $login;
        if($user->admin == 1){
            $_SESSION["admin"]=1;
        }
        $sess = new Ses();
        $sess->userId = $user->id;
        $sess->id = $sid;
        $sess->save();
        return $response->withStatus(200)->withHeader('Location', '/');
    }else{
        $args['login_error']=true;
        return $this->renderer->render($response, 'login.phtml', $args);
