How do you log in a user in FuelPHP?

To log in a user in FuelPHP, you typically use the Auth package, which provides an easy way to handle user authentication. Here are the minimal steps to log in a user:

Step 1: Load the Auth Package

Ensure that the Auth package is enabled in your config file. Open fuel/app/config/config.php and ensure the auth package is loaded.

Example

<?php
'always_load'  => array(
    'packages'  => array(
        'auth',
    ),
),
?>

Step 2: Log in the User

You can log in a user by using the Auth::login() method. Typically, you’ll do this in a controller where users submit their credentials.

Example

<?php
// In a controller method, for example:
if (Auth::login($username, $password)) {
    // Login successful
    echo 'Login successful';
} else {
    // Login failed
    echo 'Invalid username or password';
}
?>
  • $username: The user’s username or email.
  • $password: The user’s password.

Step 3: Check if User is Logged In

Once the user is logged in, you can check whether a user session is active using the Auth::check() method.

Example

<?php
if (Auth::check()) {
    // User is logged in
    echo 'User is logged in';
} else {
    // User is not logged in
    echo 'No user session';
}
?>

Step 4: Log Out the User

To log out a user, simply call the Auth::logout() method.

Example

<?php
Auth::logout();
?>
