The Validation library is built to work with Laravel's Validation Framework and provides over 30 additional validation rules including error messages. You can use this rules in combination with Laravel's rules by passing them to the validator.

Example with Controller

use Intervention\Validation\Rules\Hexadecimalcolor;

public function store(Request $request): RedirectResponse
{
    $validated = $request->validate([
        'color' => new Hexadecimalcolor(3), // pass rule as object
        'number' => ['required', 'creditcard'], // or pass rule as string
        'name' => 'required|min:3|max:20|username', // combining rules works as well
    ]);
 
    // The data is valid...
}

Example with Form Request Validation

use Intervention\Validation\Rules\Hexadecimalcolor;

public function rules(): array
{
    return [
        'color' => new Hexadecimalcolor(3), // pass rule as object
        'number' => ['required', 'creditcard'], // or pass rule as string
        'name' => 'required|min:3|max:20|username', // combining rules works as well
    ];
}

Example with Manually Created Validator

use Illuminate\Support\Facades\Validator;
use Intervention\Validation\Rules\Hexadecimalcolor;

$validator = Validator::make($request->all(), [
    'color' => new Hexadecimalcolor(3), // pass rule as object
    'number' => ['required', 'creditcard'], // or pass rule as string
    'name' => 'required|min:3|max:20|username', // combining rules works as well
]);

Customizing Error Messages

Add the corresponding key to /resources/lang/<language>/validation.php like this:

'iban' => 'Please enter IBAN number!',

Or add your custom messages directly to the validator like described in the Laravel docs.
