page-independent frontend-login

[demlak]

hey.. logging out is possible by visiting /logout
But whats a solution for a simple frontend login-page with maybe redirect to / after login?

accessing /no-permission to login, results into:

TypeError thrown with message "Argument 1 passed to go() must be of the type string, null given, called in /var/www/html/site/plugins/kirby-securedpages-1.2.0/src/loginform/LoginFormCtrl.php on line 31"

Stacktrace:
#9 TypeError in /var/www/html/kirby/config/helpers.php:223
#8 go in /var/www/html/site/plugins/kirby-securedpages-1.2.0/src/loginform/LoginFormCtrl.php:31

#0 Kirby\Cms\App:render in /var/www/html/index.php:35

so it seems there needs to be a default argument to let go() never go empty.

my solution in src/loginform/LoginFormCtrl.php:

        if ($form->success()) {
//            go(get('prevloc'));
            if (!empty(get('prevloc'))) {
                go(get('prevloc'));
            } else {
                go('/');
            }
        }

no, it is possible to go to /no-permission to get default Login-Page. And after Login, you are redirected to /

this could also be changed to a specific option like kerli81.securedpages.loginform.default.go or similar..
