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 (optional)

The Validation library is built to work with the Laravel Framework (>=5.5). It comes with a service provider, which will be discovered automatically and registers the validation rules into your installation.

Usage

use Intervention\Validation\Validator;
use Intervention\Validation\Rules\HexColor;
use Intervention\Validation\Exception\ValidationException;

// create validator (for HexColor)
$validator = new Validator(new HexColor);

// validate against given values
$valid = $validator->validate('#ccc'); // true
$valid = $validator->validate('www'); // false

// change the validation rule
$validator->setRule(new Domainname);

// now validate new rule domainname
$valid = $validator->validate('foo.com'); // true
$valid = $validator->validate('?'); // false

// validator can also throw exceptions on invalid data. 
// just call assert() instead of validate().
try {
    $validator->assert('foobar');
} catch (ValidationException $e) {
    echo $e->getMessage();
}

Static Usage

use Intervention\Validation\Validator;
use Intervention\Validation\Rules\HexColor;
use Intervention\Validation\Exception\ValidationException;

// create validator statically
$valid = Validator::make(new HexColor)->validate('ccc'); // true
$valid = Validator::make(new HexColor)->validate('#www'); // false

// throw exceptions on invalid data instead of returning boolean
try {
    Validator::make(new HexColor)->assert('www');
} catch (ValidationException $e) {
    echo $e->getMessage();
}

Static dynamic call Usage

use Intervention\Validation\Validator;
use Intervention\Validation\Rules\HexColor;
use Intervention\Validation\Exception\ValidationException;

// call validation rule directly via static method
$valid = Validator::isHexColor('#ccc'); // true
$valid = Validator::isHexColor('#www'); // false

// throw exceptions on invalid data
try {
    Validator::assertHexColor('foo');
} catch (ValidationException $e) {
    echo $e->getMessage();
}

Usage with Laravel

The installed package provides additional validation rules including their error messages.

use Illuminate\Support\Facades\Validator;

$validator = Validator::make($request->all(), [
    'color' => 'required|hexcolor',
    'number' => 'iban',
]);

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.
