Installation
The package could be installed with composer:
composer require yiisoft/validator
General usage
Validator allows to check data in any format. For example, when data is an object:
use Yiisoft\Validator\Rule\AtLeast; use Yiisoft\Validator\Rule\Email; use Yiisoft\Validator\Rule\Length; use Yiisoft\Validator\Rule\Number; use Yiisoft\Validator\Rule\Required; use Yiisoft\Validator\Validator; #[AtLeast(['email', 'phone'])] final class Person { public function __construct( #[Required] #[Length(min: 2)] public ?string $name = null, #[Number(min: 21)] public ?int $age = null, #[Email] public ?string $email = null, public ?string $phone = null, ) { } } $person = new Person( name: 'John', age: 17, email: 'john@example.com', phone: null ); $result = (new Validator())->validate($person);
The validation result is an object that allows to check whether validation was successful:
$result->isValid();
It also contains errors occurred during validation:
$result->getErrorMessages();
