Features -------- [](#features) - Validates any data: arrays, objects, scalar values, etc. - Supports custom data sets. - Handles nested data structures (one-to-one and one-to-many). - Can read validation rules from PHP 8 attributes. - Error message formatting and translation. - Attribute names translation. - Conditional validation: - Skip validation of "empty" value with possibility to configure "empty" condition. - Skip further validation if an error occurred for the same property. - 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 ------------ [](#requirements) - PHP 8.1 - 8.5. - `mbstring` PHP extension. Installation ------------ [](#installation) The package could be installed with [Composer](https://getcomposer.org): ``` composer require yiisoft/validator ``` General usage ------------- [](#general-usage) Validator allows to check data in any format. For example, when data is an object: ``` use Yiisoft\Validator\Rule\FilledAtLeast; use Yiisoft\Validator\Rule\Email; use Yiisoft\Validator\Rule\Length; use Yiisoft\Validator\Rule\Number; use Yiisoft\Validator\Rule\Required; use Yiisoft\Validator\Validator; #[FilledAtLeast(['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(); ``` Documentation ------------- [](#documentation) - Guide: [English](docs/guide/en/README.md), [Português - Brasil](docs/guide/pt-BR/README.md) - [Internals](docs/internals.md) If you need help or have a question, the [Yii Forum](https://forum.yiiframework.com/c/yii-3-0/63) is a good place for that.
