Laravel How to check whether the user is authorized

Laravel: How to check if a user is authenticated, with example code.

In order to check whether a user is authorized or not in Laravel, we can use the Auth facade. The Auth facade provides a convenient way to check if a user is authenticated or not. It can be used in both the blade template and in the controller. We will look at how to use it in both places.

Using the Auth Facade in Blade Templates

The Auth facade has a few different methods that can be used to check if a user is authenticated or not. The most common way to check if a user is authorized is using the check() method. This method takes a single argument, which is the guard to check. If the user is authenticated, it will return true, otherwise, it will return false.

@if (Auth::check())
    // The user is logged in...
@endif

We can also use the Auth::user() method to get the currently authenticated user. This method will return an instance of the currently logged in user, or null if the user is not authenticated.

@if (Auth::user())
    // The user is logged in...
@endif

Finally, we can use the Auth::id() method to get the ID of the currently authenticated user. This method will return the ID of the user, or null if the user is not authenticated.

@if (Auth::id())
    // The user is logged in...
@endif

Using the Auth Facade in Controllers

The Auth facade can also be used in controllers. We can use the same methods we used in the blade template, such as check(), user(), and id(). Here is an example of how to use the check() method in a controller:

if (Auth::check()) {
    // The user is logged in...
}

We can also use the user() and id() methods in the controller as well. Here is an example of how to use the user() method:

if (Auth::user()) {
    // The user is logged in...
}

And here is an example of how to use the id() method:

if (Auth::id()) {
    // The user is logged in...
}

In summary, the Auth facade provides a convenient way to check if a user is authenticated or not in Laravel. We can use the check(), user(), and id() methods to check if a user is authorized or not. We can use these methods in both the blade template and in the controller.
