## Installation

You can install this package quick and easy with Composer.

Require the package via Composer:

$ composer require intervention/validation

## Laravel integration

The Validation library is built to work with the Laravel Framework (>=10). It
comes with a service provider, which will be discovered automatically and
registers the validation rules into your installation. The package provides 37
additional validation rules including multi language error messages, which can
be used like Laravel's own validation rules.

```php
use Illuminate\Support\Facades\Validator;
use Intervention\Validation\Rules\Creditcard;
use Intervention\Validation\Rules\Hexadecimalcolor;
use Intervention\Validation\Rules\Username;

$validator = Validator::make($request->all(), [
    'color' => new Hexadecimalcolor([3, 6]), // pass rule as object
    'number' => ['required', 'creditcard'], // or pass rule as string
    'name' => 'required|min:3|max:20|username', // combining rules works as well
]);
```

### Changing the error messages:

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

```php
// example
'iban' => 'Please enter IBAN number!',
```
Or add your custom messages directly to the validator like [described in the docs](https://laravel.com/docs/10.x/validation#manual-customizing-the-error-messages).
