Login Status on every page

Bill Lions

I wish to put the login status of a user in the top bar of my site.
This is simple enough, but how to share this logic across multiple presenters, and to the template, without reproducing the code for each presenter?

$user variable is available in each template by default

Use @layout.latte

Soo, in the layout,

{php echo $user->username}

Or something?

manwe

instead of {php echo $user->username} you can just use {$user->username}.

But check the $user variable to check whats inside.
Its filled by authenticator.

I get an error

Nette\MemberAccessException
Cannot read an undeclared property Nette\Security\User::$username

My authenticator is basically a copy from the tutorial on https://doc.nette.org/…thentication


class UserAuthenticator implements Nette\Security\IAuthenticator
{
        private $database;

        public function __construct(Nette\Database\Context $database)
        {
                $this->database = $database;
        }

        public function authenticate(array $credentials)
        {
                list($username, $password) = $credentials;
                $row = $this->database->table('users')
                        ->where('username', $username)->fetch();

                if (!$row) {
                        throw new Nette\Security\AuthenticationException('User not found.');
                }

                if (!Nette\Security\Passwords::verify($password, $row->password)) {
                        throw new Nette\Security\AuthenticationException('Invalid password.');
                }

                return new Nette\Security\Identity($row->id, $row->role, ['username' => $row->username]);
        }
}

My latte template has

<li>{$user->username}</li>

MajklNajt

you should use {$user->getIdentity()->username}

So, that gets rid of the error, but does not show the value.
Is there something in the UserAuthenticator that I am doing/not doing to cause this?

manwe

dump the $user variable to Tracy using
{dump $user}
to see whats inside, if everything is set correctly
