I am trying to troubleshoot a form using Google recaptcha version 1.0 - when the form gets submitted the g-recaptcha-response is filled which means Google is happy this is real person but the ReCaptchaResponse is empty meaning the form does not submit as I cannot be sure this is a real person.
When the form is submitted this is the value in $_POST:
[g-recaptcha-response] => 03AHJ_Vuvki7OVSl6bZug1NN5WPOK4HUiLmhAFMMl1RmEiwWzn-tIJ8iryAe01Z-RjzaAtfBKP2ITFc2SnrTV3v7CG7YosOspqXuMSuLDgHCqWG7CEdSCxlSUaaB6joNtOQYPTi0vP4n6sfupG0GfnjMkxJPnEfEnNvsCimsvtIkUbHfY18bYzXTarXCqjb_R_EHcnIl0zm5HhpIeJUFaJYqgivz1gRqkR_BZhlKzvCkVQkRw9Zl-RVRgThUFqI_IFjRnL5ZE5eV1VwrEZFx9j8AOq1gkYw6Cjk8wYSRp9Ax816ifnyYAPtV_NIM6qBpM3NfTejlZ0FT0fu7Kd5mqOFllqSaRVOpSdT-W2HrL4EkNBIeA-YrDwPu9-8-lX3WtZY6kvdm_9Cb_8I1tjKoAmu70mXC0yl5i9Rf0NluS_hAGwCIZFDW9V5PtiiYeD9HpiW3h4nZpzBKAC3FaRuQZNKfTEMPO0TelIlQ [submit] => ) And this is content of ReCaptchaResponse:
ReCaptchaResponse Object ( [success] => [errorCodes] => ) Here is the code I am using to validate the response - it always fails on !$response->success which makes sense as success is empty but why is it empty when g-recaptcha-response is populated?
$secret= "MY_SECRET"; require_once('recaptchalib.php'); $reCaptcha = new ReCaptcha($secret); if ($_POST["g-recaptcha-response"]) { $response = $reCaptcha->verifyResponse( $_SERVER["REMOTE_ADDR"], $_POST["g-recaptcha-response"] ); print_r($response); print $response->success; print $response->error-codes; if ($response == null) { $error_message='<p>Please validate your captcha response 1</p>'; $error=1; } elseif (!$response->success){ $error_message='<p>Please validate your captcha response 2</p>'; $error=1; } } else { $error_message='<p>Please validate your captcha response 3</p>'; $error=1; }
