                            alert("success");
                        }
                        else {
                            alert("fail");
                        }
                  }
                });
    }
        }

PHP

$response = $_POST['captcha'];

$privatekey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"; 
$param = "https://www.google.com/recaptcha/api/siteverify?secret=".$privatekey."&response=".$response;
$verifyResponse = file_get_contents($param);
$responseData = json_decode($verifyResponse);

    if($responseData->success){
    echo  'success';
    }

  • What appears from code debugging in the browser?

  • Nothing appears. On the Chrome network appears that the POST is OK, IE, was sent correctly.

  • Try to print the variable dump $responseData. Something like var_dump($responseData), just don’t put inside the if.

  • object(stdClass)[1]&#xA; public 'success' => boolean false&#xA; public 'challenge_ts' => string '2017-11-05T13:28:45Z' (length=20)&#xA; public 'hostname' => string '127.0.0.1' (length=9)&#xA; public 'error-codes' => &#xA; array (size=1)&#xA; 0 => string 'invalid-keys' (length=12)

  • I think the code is breaking, or the same expires until I send the request to it.

For the message that returned, it must be that in the Google Recaptcha Admin you do not have the host that is sending the request, in the case of localhost/127.0.0.1, registered and with a key. Try adding this host as well and using this new key.
