requests

To separate validation logic from Laravel controllers, create dedicated Form Request classes under app/Http/Requests. Injecting these classes into your controller methods automatically validates user input before the action executes, keeping your controllers clean.

The best way to authorize user input in Laravel form requests is by implementing the authorize() method within your dedicated FormRequest class. This gates access before the controller action runs, providing centralized security and preventing unauthorized data modifications.

To define custom validation rules for a Laravel resource, add a rules() method to your Store{Resource}Request or Update{Resource}Request class. This centralizes all input constraints in one location, which Laravel applies automatically upon form submission.

Laravel form request validation supports custom error messages by implementing the messages() method in your FormRequest class. This allows you to return user-friendly validation errors tailored to specific input fields instead of relying on default framework messaging.

You need to use a dedicated form request class in Laravel when creating or updating resources to enforce consistent validation rules. Replacing inline controller validation with a request class groups your rules by domain and improves overall project maintainability.

You can use PHPDoc annotations with Laravel form requests to support static analysis. Adding these annotations to your authorize(), rules(), and messages() methods provides clear type hints and access control documentation for your IDE and analysis tools.
