Installation
The preferred way to install this extension is through composer.

$ php composer.phar require alexeevdv/yii2-recaptcha-widget "^1.0"
or add
"alexeevdv/yii2-recaptcha-widget": "^1.0"
to the require
section of your composer.json
file.
Configuration
Through application component
'components' => [ //... 'recaptcha' => [ 'class' => \alexeevdv\recaptcha\Recaptcha::class, 'siteKey' => 'YOUR_SITE_KEY', 'secret' => 'YOUR_SECRET', ], //... ],
Through widget and validator params
use alexeevdv\recaptcha\RecaptchaValidator; use alexeevdv\recaptcha\RecaptchaWidget; // Model validation rules public function rules() { return [ //... [ ['recaptcha'], RecaptchaValidator::class, 'secret' => 'YOUR_SECRET', 'minimalScore' => 0.6, 'onScoreReceived' => function ($score) { // Do smth on actual user score. F.e. log it somewhere }, ], //... ]; } // Widget params echo RecaptchaWidget::widget([ 'siteKey' => 'YOUR_SITE_KEY', ]);
Usage
use alexeevdv\recaptcha\RecaptchaValidator; use alexeevdv\recaptcha\RecaptchaWidget; // Using ActiveForm // In this case model validation rules will be applied // You'll need to specify RecaptchaValidator for attribute echo $form->field($model, 'recaptcha')->widget(RecaptchaWidget::class); // As standalone field echo RecaptchaWidget::widget(['name' => 'recaptcha']); // In this case you need to check value manually $validator = new RecaptchaValidator(); $isValid = $validator->validateValue(Yii::$app->request->get('recaptcha'));
Usage in tests
To turn off recaptcha checking you need to add this in your test config:
'container' => [
'definitions' => [
\alexeevdv\recaptcha\RecaptchaValidator::class => ['skipOnEmpty' => true],
],
],
