Google reCaptcha says:invalid-request-cookie
php, recaptcha
Solution
As reCAPTCHA Support says:
No, this will not result in the invalid domain. What this means is that you are not submitting the recaptcha_challenge_field to the server correctly.
So make sure you rendering the form with recapcha corectly. Check out this link.
Problem
this is my first time in using recaptcha on my website. I'm using PHP API to validate the recaptcha, it keeps saying `invalid-request-cookie` I found out on different forum that www.example.com is different with example.com, so I register my site again without `www` , but still it is not working.. When I verify the `recaptcha_response_field` and `recaptcha_challenge_field` the values are correct. here is the captcha checker: ``` require_once(recaptchalib.php'); $publickey = "not displayed"; //for security $privatekey = "not displayed"; //for security $error = null; if( $_POST ) { $arr = array('a' => $_POST['task'], 'b' => $_POST['recaptcha_challenge_field'], 'c' => $_POST['recaptcha_response_field']); if( trim($arr['a']) == 'captcha' ) { $resp = null; $error = null; $captcha_result = 'success'; $resp = recaptcha_check_answer( $privatekey, $_SERVER["REMOTE_ADDR"], $arr['b'], $arr['c'] ); if( $resp->error ){ $captcha_result = 'fail'; } echo $captcha_result; } } ``` here is the HTML code: ``` <div id="captcha-div"> <script type="text/javascript"> var RecaptchaOptions = { tabindex: 1, theme: 'custom', custom_theme_widget: 'recaptcha_widget' }; </script> <div id="recaptcha_widget" style="display:none"><div id="recaptcha_image" style="width: 200px; height: 57px; "></div> <?php echo recaptcha_get_html($publickey, $error); ?> <div class="recaptcha_only_if_incorrect_sol" style="color:red">Incorrect.
