Yii2 invisible recaptcha component

Validates your ActiveForm using Google invisible-recaptcha

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist bariew/yii2-invisible-recaptcha "*"

or add

"bariew/yii2-invisible-recaptcha": "*"

to the require section of your composer.json file.

Usage

1. Set application config params:

   'params' => [
   ...
       'invisible-recaptcha-key' => '<Your Key>',
       'invisible-recaptcha-secret'  => '<Your Secret>'
   ]

2. Add verification attribute and a validation rule into your model rules:

   public $verifyCode;
   
   /**
    * @inheritdoc
    */
   public function rules()
   {
       return [
           ...
           ['verifyCode', InvisibleRecaptchaValidator::className(), 'message' => 'Invalid captcha value'],
       ];
   }

3. Use widget instead of ActiveForm submit button in your view:

   <?= $form->field($model, 'verifyCode')->widget(\bariew\invisibleRecaptcha\InvisibleRecaptchaWidget::className(), [
       'buttonText' => 'Save' ,
       'options' => ['class' => 'btn btn-primary'],
   ]); ?>
