hi there, I have a problem using ZendService\ReCaptcha\ReCaptcha in my Contact form. I already registered in https://www.google.com/recaptcha/admin.
I also installed ZendService\ReCaptcha\ReCaptcha from https://github.com/zendframework/ZendService_ReCaptcha and here is my composer.json code:

    "test": "phpunit"
     }
  }

here is my Contact\Controller\IndexController for using re-captcha:

        public function indexAction()
        {
            $recaptcha = new \ZendService\ReCaptcha\ReCaptcha(
            'PUB_KEY',
            'PRIVATE_KEY'); 
             return new ViewModel
            ([
            'recaptcha'=>$recaptcha,
            ]);
        }

and here the index.phtml code:

            echo $this->recaptcha->getHTML();
            if(isset($_POST['recaptcha_response_field'])){
                $recaptcha_challenge =$_POST['recaptcha_challenge_field'];
                $recaptcha_response = $_POST['recaptcha_response_field'];
                if(isset($recaptcha_challenge)&&
                    isset($recaptcha_response) ||
                    !empty($recaptcha_challenge)&&
                    !empty($recaptcha_response)){
                    $result = $this->recaptcha->verify(
                        $recaptcha_challenge,
                        $recaptcha_response
                    );
                    if (!$result->isValid())
                    {
                        echo $result->getErrorCodes();
                    }
                }
            }

but after all my form is submitted without filling re-captcha part. and there is no error. what should I do?

I haven’t used ZendService_ReCaptcha myself so I can’t help you with that. But I do hope those are not your real recaptcha keys, although they don’t look like the official test keys. You have a public and a secret key for a reason!

EDIT: Removed the keys for you. I suggest to create a new set and don’t post those on a public forum.

the work is done by adding ZendService\ReCaptcha . then back to Controller and instantiate the class using $recaptcha = new \ZendService\ReCaptcha\ReCaptcha($pubKey, $privKey); the next step will be pass $recaptcha to specified ViewModel and in the view(in my project index.phtm) render the html recaptcha field using recaptcha->getHTML(). when a user fill out the recaptcha in the controller we receive **_POST[‘g-recaptcha-response’]** . check the validation in Controller:

$result =$recaptcha->verify( $_POST['g-recaptcha-response'])
if(!$result->isValid())
{
 throw new \Exception('recaptcha is not valid');
}

and that’s all the following code is your specific logic to handle form submission!
