How to check user is login or not in Laravel

if you want to check the user is logged in or not, you can use the Auth facade or the auth() helper function. Here’s how you can do it:

1. Use the Auth Facade

The Auth::check() method returns true if the user is logged in, and false if the user is not logged in.

use Illuminate\Support\Facades\Auth;

if (Auth::check()) {
// User is logged in
return "User is logged in.";
} else {
// User is not logged in
return "User is not logged in.";
}

2. Use the auth() Helper

You can get the same results by using the auth() helper.

if (auth()->check()) {
// User is logged in
return "User is logged in.";
} else {
// User is not logged in
return "User is not logged in.";
}

3. In Blade Views

To conditionally check the user’s login status in Blade templates, use the following code:

@if(Auth::check())
<p>User is logged in.</p>
@else
<p>User is not logged in.</p>
@endif

Alternatively, use auth():

@if(auth()->check())
<p>User is logged in.</p>
@else
<p>User is not logged in.</p>
@endif

4. Middleware Approach

To make sure routes are only accessible to logged-in users, use Laravel’s  auth middleware. Define it in your routes:

Route::get('/dashboard', function () {
return view('dashboard');
})->middleware('auth');

For routes that should only be accessible to guests, use the guest middleware:

Route::get('/login', function () {
return view('login');
})->middleware('guest');

5. Checking the Authenticated User’s Data

If you want to get the logged-in user’s details, use the Auth::user()  or  auth()->user():

$user = Auth::user(); // or auth()->user();
if ($user) {
return "Logged-in user: " . $user->name;
} else {
return "No user is logged in.";
}
