Log in and out

The auth module provides methods to help you log users in and out of your application.

Log in

The Auth::login method handles the login.

// Handled from a form with inputs with names email / password
$post = $this->request->post();
$success = Auth::instance()->login($post['email'], $post['password']);

if ($success) {
    // Login successful, send to app
} else {
    // Login failed, send back to form with error message
}

Logged in User

There are two ways to check if a user is logged in. If you just need to check if the user is logged in use Auth::logged_in.

if (Auth::instance()->logged_in()) {
    // User is logged in, continue on
} else {
    // User isn't logged in, redirect to the login form.
}

You can also get the logged in user object by using Auth::get_user. If the user is null, then no user was found.

$user = Auth::instance()->get_user();

// Check for a user (null if not user is found)
if ($user !== null) {
    // User is found, continue on
} else {
    // User was not found, redirect to the login form
}

Log out

The Auth::logout method will take care of logging out a user.

Auth::instance()->logout();
// Redirect the user back to login page
