Strange output for a php request of $_SESSION

[Antoviscomi]

When I try to obtain informations on active LWC(PHP) session in my machine by

session_start(); echo '<pre>'; print_r($_SESSION); echo '</pre>';

I receive this response caused by a request that throws an error about an incomplete object in the PHP session:

`(
    [JX_LANG] => it_IT
    [JELIX_USER] => __PHP_Incomplete_Class Object
        (
            [__PHP_Incomplete_Class_Name] => cDaoRecord_lizmap_Jx_user_Jx_pgsql
            [__dao_profile:protected] => jauth
            [login] => admin
            [email] => [email protected]
            [password] => $2y$10$kHglBdPNhE8gwddEewV.YOXJZQJbT9YhzdR254rAqcCWFUMpIN2g2
            [firstname] => 
            [lastname] => 
            [organization] => 
            [phonenumber] => 
            [street] => 
            [postcode] => 
            [city] => 
            [country] => 
            [comment] => 
            [status] => 1
            [keyactivate] => 
            [request_date] => 
            [create_date] => 2023-07-18 09:51:11.441193
        )

    [JFORMS_SESSION] => __PHP_Incomplete_Class Object
        (
            [__PHP_Incomplete_Class_Name] => jFormsSession
        )

)`

then I'm not able to pass $_SESSION info to another php because of session crash.
can someone tell me if is it a bug or a misconfiguration caused by me?
And in both cases what can i do?

According to stack overflow, it's because the "cDaoRecord_lizmap_Jx_user_Jx_pgsql" (and jFormsSession) classes are unknown when session is deserialized (by print_r)

If you want to know the currrent user in session, you need to use jelix/lizmap objects ( jAuth::getUserSession()) or ensure the class used by object in session are defined.

If you want to know the currrent user in session, you need to use jelix/lizmap objects ( jAuth::getUserSession()) or ensure the class used by object in session are defined.

using jAuth::getUserSession() as follow:

try {
    // Prova a ottenere la sessione utente
    $user = jAuth::getUserSession();

    if ($user && !($user instanceof jAuthDummyUser)) {
        // Controlla che l'utente abbia le proprietà id e group
        $userId = isset($user->id) ? $user->id : 'N/A';
        $group = isset($user->group) ? $user->group : 'N/A';
        error_log("Debug: Utente connesso. ID: $userId, Gruppo: $group");

        // Verifica se l'utente è admin o registrato
        if (in_array($group, ['admins', 'users'])) {
            error_log("Debug: Utente autorizzato.");
            // Includi il form HTML o reindirizza alla pagina protetta
            // include '/var/www/webgism/lizmap/www/mapsm/myscript.php';
            exit;
        } else {
            error_log("Debug: Utente non autorizzato." . print_r($user, true));
        }
    } else {
        error_log("Debug: Utente non autenticato o autenticazione fallita.");
    }
} catch (Exception $e) {
    error_log("Debug: Errore durante il recupero della sessione utente: " . $e->getMessage());
}

my debug log come out as you can see after successful login in LWC

PHP message: Debug: Utente connesso. ID: , Gruppo: ', referer: http://xxx.xx.xx.xx/webgism/admin.php/auth/login?auth_url_return=%2Fwebgism%2Fmapsm%2Fmyscript.php

the ACL groups to which the user belongs can be found with \jAcl2DbUserGroup::getGroups();

@nworr my mistake! The php session path was not readable to the system group, so the signal returned by jAuth::getUserSession() was null!
