The package provides a base for form models and helps to fill them with data, validate them and display them.

Requirements

• PHP 8.1 - 8.5.
• mbstring PHP extension.

Installation

The package could be installed with Composer:

composer require yiisoft/form-model

General usage

Define a form model:

use Yiisoft\FormModel\Attribute\Safe;
use Yiisoft\FormModel\FormModel;
use Yiisoft\Validator\Rule\Email;
use Yiisoft\Validator\Rule\Length;
use Yiisoft\Validator\Rule\Required;

final class LoginForm extends FormModel
{
 #[Label('Your login')]
 #[Required]
 #[Length(min: 4, max: 40, skipOnEmpty: true)]
 #[Email(skipOnEmpty: true)]
 private ?string $login = null;

 #[Label('Your password')]
 #[Required]
 #[Length(min: 8, skipOnEmpty: true)]
 private ?string $password = null;

 #[Label('Remember me for 1 week')]
 #[Safe]
 private bool $rememberMe = false;
}

Fill it with data and validate using form hydrator:

use Psr\Http\Message\RequestInterface;
use Yiisoft\FormModel\FormHydrator;
use Yiisoft\FormModel\FormModel;

final class AuthController 
{
 public function login(RequestInterface $request, FormHydrator $formHydrator): ResponseInterface
 {
 $formModel = new LoginForm();
 $errors = [];
 if ($formHydrator->populateFromPostAndValidate($formModel, $request)) {
 $errors = $formModel->getValidationResult()->getErrorMessagesIndexedByProperty();
 }
 
 // You can pass $formModel and $errors to the view now.
 }
}

Display it using fields in the view:

use Yiisoft\FormModel\Field;
use Yiisoft\FormModel\FormModel;

echo Field::text($formModel, 'login');
echo Field::password($formModel, 'password');
echo Field::checkbox($formModel, 'rememberMe');

// ...
