  • Skip further validation if an error occurred for the same attribute.
  • Skip validation depending on a condition.
• Possibility to use context in rule handler.
• Common rules bundled.
• Supports DI container for creating custom rule handlers with extra dependencies.
• Exporting rules options for using in the frontend.

Requirements

• PHP 8.0 or higher.
• mbstring PHP extension.

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: '[e-mail]',
    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();
