Step 1: Understand the Error

Before we dive into the solution, let's understand why this error occurs. In Laravel, this error occurs when the user does not have the necessary permissions to perform a specific action, such as submitting a form or accessing a resource.


Step 2: Create a Form Request Class

To handle form validation and authorization in Laravel, we use Form Request classes. These classes allow us to encapsulate the validation rules and authorization logic for a specific request. Let's create a Form Request class for our form:

php artisan make:request MyFormRequest


Step 3: Define Validation Rules

Next, open the generated MyFormRequest class located in the app/Http/Requests directory. Define your validation rules in the rules() method. For example.

public function rules()
    return [
        'name' => 'required|string|max:255',
        'email' => 'required|email|unique:users,email,' . auth()->id(),
        // Add more validation rules as needed


Step 4: Define Authorization Logic

Now, let's define the authorization logic to ensure that only authorized users can act. Override the authorize() a method in your Form Request class:

public function authorize()
    // Check if the user is authorized to perform the action
    return true; // Example: Allow all authenticated users


Step 5: Handle Authorization Error

If the user is not authorized to act, Laravel will automatically throw an AuthorizationException. To handle this exception and display a custom error message, you can override the failedAuthorization() method in your Form Request class:

protected function failedAuthorization()
    throw new \Illuminate\Auth\Access\AuthorizationException('You are not authorized to perform this action.');


Step 6: Use Form Request in the Controller

Finally, use your Form Request class in your controller method to handle the form submission:

use App\Http\Requests\MyFormRequest;

public function store(MyFormRequest $request)
    // Form request is validated and authorized
    // Continue with your controller logic



And there you have it! By following these steps, you can effectively handle the "This action is unauthorized" error using Form Request validation in Laravel 10.
