What Happens When Using Auth::user()->id In PHP Laravel And The Object Doesn’t Exist?

The error "Trying to get a property of a non-object" in Laravel occurs when you try to access a property of an object that doesn’t exist or is null. In this case, it seems that the Auth::user() is returning null instead of an object.

This issue can typically happen when there is no authenticated user, meaning the user is not logged in or the current request does not have a valid session. Here are a few possible reasons and solutions:

  1. Make sure you are using the auth middleware in your route or controller to enforce authentication. For example, in your route definition:
Route::get('/profile', 'ProfileController@index')->middleware('auth');
  1. Verify that you have set up the authentication system correctly in your Laravel application. Check your config/auth.php file to ensure you have the correct authentication guards and providers configured.

  2. Ensure that you have properly logged in the user before accessing Auth::user()->id. You can use the Auth::check() method to verify if the user is authenticated before accessing their data. For example:

if (Auth::check()) {
    $userId = Auth::user()->id;
    // Rest of your code
} else {
    // Handle the case when user is not authenticated
}
  1. If you are using the default Laravel authentication system, make sure you have included the web middleware in your routes. For example, in your routes/web.php file:
Route::middleware(['web'])->group(function () {
    // Your routes here
});

By following the above suggestions, you should be able to resolve the "trying to get a property of a non-object" error when accessing Auth::user()->id in Laravel.
