How can I validate route parameters in Laravel?

In Laravel, you can validate route parameters using route model binding or by defining validation rules in your controller.

Can you give me an example of route model binding?

Sure! You can define a route like this: Route::get('/user/{user}', 'UserController@show'); and Laravel will automatically fetch the user model based on the ID.

What if I want to validate the ID format?

You can use route constraints. For example: Route::get('/user/{id}', 'UserController@show')->where('id', '[0-9]+'); This ensures the ID is numeric.

Is there a way to return a custom error message?

Yes! You can customize error messages in your controller by using the Validator facade and specifying messages in the validate method.
