Hello.There is currently no way to hide objects depending on the user group.You can allow access for certain groups of users to certain pages.

Franco, further to what Aleksej correctly stated, you could have a locked page to which only appropriate groups get access, and on that page add a menu object starting at a (hidden) level under which all the user pages have been placed. Until a user logged in to see that page the menu would not be visible.

So, what is exactly the group that is retrieved by that function (in x5engine.php)?

I've displayed into a page and i so is something coded.

public function getUserByUsername($username)
    {
        $imSettings = Configuration::getSettings();        // Search in the file
        if (isset($imSettings['access']['users'][$username])) {
            $user = $imSettings['access']['users'][$username];
            return array(
                "id"        => $user['id'],
                ...
                "validated" => true,
                "groups"    => $user['groups'],
                "hash"      => $this->_getUserHash($username, $user['password'])
            );
        }
        // Search in the DB
        if ($this->db) {
            $res = $this->db->query("SELECT * FROM `" . $this->db_table . "` WHERE `email`='" . $this->db->escapeString($username) . "'");
            if (is_array($res) && count($res) > 0) {
                $user = $res[0];
                return array(
                    "id"        => $user['id'],
                    ..
                    "validated" => $user['validated'],
                    "groups"    => array($imSettings['access']['webregistrations_gid']),
                    "hash"      => $this->_getUserHash($user['email'], $user['password'])
                );
            }
        }
        return null;
    }

By checking x5engine.php i've found this function:

public function checkAccess($page)

Is there ANY way to get the id number of certain pages?

What if i set 3 hidden pages for the 3 type of level of user and by this function i can know if the actual user belong to any of those level, so i will know which level is the user?!

I just saw that page ID is compiled runtime, so i think it can dinamically change between download!

Suddenly I am out of my depth.

Good luck playing with code.
