This extension adds new model validator components for Yii2 frameworkor and/or enhances existing Yii2 model validators.

The EmailValidator extends the yii\validators\EmailValidator component to support multiple email inputs for Yii2 framework. In addition this validator allows setting the multiple property and setting the min and max number of email addresses allowed. This is useful for adding validation rules to your attributes in the model and also adds enhanced client validation support for ActiveForm inputs at runtime via Javascript.

The PhoneValidator extends the yii\validators\Validator component using libphonenumber-for-php based on Google's libphonenumber library.

The CardValidator extends the yii\validators\Validator component. It validates standard debit and credit card number inputs using Luhn's checksum validation. It also helps auto detect the card types and additionally validating the card holder name, expiry date and CVV entered.

The JsonValidator extends the yii\validators\Validator component. It validates JSON input in text area fields. The validator also helps to overwrite the JSON input as a pretty format via prettify setting. It includes both server and client validations.

Usage

EmailValidator

This class extends the yii\validators\EmailValidator class to offer multiple email validation support. The EmailValidator class can be easily used via the alias k-email in your model validation rules. For example in your model you can use this as shown below:

use yii\db\ActiveRecord;

class EmailModel extends ActiveRecord {
    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            [['to', 'cc', 'bcc'], 'k-email', 'allowName' => true, 'enableIDN' => true, 'max' => 5],
        ];
    }
}

In your view where you render the model inputs with ActiveForm - you may set enableClientValidation to control whether you need client side validation.

// views/email/send.php

use yii\widgets\ActiveForm;

$form = ActiveForm::begin(['enableClientValidation' => true]);
echo $form->field($model, 'to')->textInput();
echo $form->field($model, 'cc')->textInput();
echo $form->field($model, 'bcc')->textInput();
// other fields
ActiveForm::end();

PhoneValidator

This class extends the yii\validators\Validator class to validate phone numbers using libphonenumber-for-php based on Google's libphonenumber library. The PhoneValidator class can be easily used via the alias k-phone in your model validation rules. For example in your model you can use this as shown below:

use yii\db\ActiveRecord;

class ContactModel extends ActiveRecord {
    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            [['phone1'], 'k-phone', 'countryValue' => 'US'],
            [['phone2'], 'k-phone', 'countryAttribute' => 'country', 'applyFormat' => false],
        ];
    }
}

CardValidator

The CardValidator extends the yii\validators\Validator component. It validates standard debit and credit card number inputs using Luhn's checksum validation. It also helps auto detect the card types and additionally validating the card holder name, expiry date and CVV entered. The CardValidator class can be easily used via the alias k-card in your model validation rules. For example in your model you can use this as shown below:

use yii\db\ActiveRecord;

class PaymentModel extends ActiveRecord {
    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            [
                ['card_number'], 
                'k-card', 
                'typeAttribute' => 'card_type', 
                'holderAttribute' => 'holderName',
                'expiryYearAttribute' => 'expiryYear',
                'expiryMonthAttribute' => 'expiryMonth',
                'cvvAttribute' => 'cvv',
            ],
        ];
    }
}

JsonValidator

The JsonValidator extends the yii\validators\Validator component. It validates JSON input in text area fields. The validator also helps to overwrite the JSON input as a pretty format via prettify setting. It includes both server and client validations. The JsonValidator class can be easily used via the alias k-json in your model validation rules. For example in your model you can use this as shown below:

use yii\db\ActiveRecord;

class ProductModel extends ActiveRecord {
    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            [
                ['products_list_json'], 
                'k-json', 
                'prettify' => true, // set this to false if you do not wish to prettify the json input
            ],
        ];
    }
}
