How to validate form input data in Laravel using built-in validation rules?

In Laravel, you can use the built-in validation rules to validate form input data. Here are the steps to do so:

Step 1: Define Validation Rules In your controller or form request class, create a rules array which defines the validation rules for each input field. For example, if you have an input field 'name' that is required and must be a string, you can define the rule 'name' => 'required|string'.

Step 2: Perform Validation In your controller or form request class, use the validate method to perform the validation. Pass the request object and the rules array to the validate method. For example, if you are using a form request class called 'RegistrationRequest', you can perform the validation like this: $validatedData = $request->validate($rules);

Step 3: Handle Validation Errors If the validation fails, Laravel will automatically redirect the user back to the previous page with the validation errors. You can display these errors in your view using the @error directive. For example, if you have a validation error for the 'name' field, you can display it like this: @error('name') {{ $message }} @enderror.

That's it! By following these steps, you can easily validate the form input data using the built-in validation rules in Laravel.
