Intervention Validation

Intervention Validation is an extension library for Laravel's own validation system. The package adds rules to validate data like IBAN, BIC, ISBN, creditcard numbers and more.

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 (>=7). It comes with a service provider, which will be discovered automatically and registers the validation rules into your installation. The package provides 30 additional validation rules including error messages, which can be used like Laravel's own validation rules.

use Illuminate\Support\Facades\Validator;
use Intervention\Validation\Rules\Creditcard;
use Intervention\Validation\Rules\HexColor;
use Intervention\Validation\Rules\Username;

$validator = Validator::make($request->all(), [
    'color' => new Hexcolor(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
]);

Changing the error messages:

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

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

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

Standalone usage

It is also possible to use this library without the Laravel framework. You won't have the Laravel facades available, so make sure to use Intervention\Validation\Validator for your calls.

use Intervention\Validation\Validator;
use Intervention\Validation\Rules\Creditcard;
use Intervention\Validation\Exceptions\ValidationException;

// use static factory method to create laravel validator
$validator = Validator::make($request->all(), [
    'ccnumber' => new Creditcard(),
    'iban' => ['required', 'iban'],
    'color' => 'required|hexcolor:3',
]);

// validate single values by calling static methods
$result = Validator::isHexcolor('foobar'); // false
$result = Validator::isHexcolor('#ccc'); // true
$result = Validator::isBic('foo'); // false

// assert single values
try {
    Validator::assertHexcolor('foobar');
} catch (ValidationException $e) {
    $message = $e->getMessage();
}
