Cakephp Google RE Captcha没有发布数据

I am getting a undefined variable error when trying to use googles reCaptcha with 'g-recaptcha-response' according to their user docs https://developers.google.com/recaptcha/docs/verify

However when i submit my user form - no data is posted from the recaptcha - this makes me believe it is a view error.

Controller funtion

if ($this->request->is('post'))
        {
            //if ($this->Recaptcha->verify()) {

                //verify captcha
                debug($this->request->data);
                $recaptcha_secret = "xxxxxxxxxxxxxxxxxxxxxxx";
                $response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$recaptcha_secret."&response=".$this->request->data['g-recaptcha-response']);
                $response = json_decode($response, true);
                if($response["success"] == true){
                }
                else{
                }
            }
        }

update:: The issue appears to be caused by div tags. I was able to resolve the issue by placing the recaptcha widget inside a particular div.

But why would this be affecting me in this way?

I'm having the same problem. g-recaptcha-response is in the POST array, but it's not in $this->data. See:

Array
(
    [_method] => POST
    [data] => Array
        (
            [BlogPostComment] => Array
                (
                    [name] => shannon
                    [email] => shannon@home.com
                    [text] => asdf
                    [blog_post_id] => 11
                    [remote_ip] => 184.00.00.001
                )

        )

    [g-recaptcha-response] => 03AHJ_VutSTvzfJze9pkzpcwQE3Xdf [ ... truncated...]

)

That's because the other form elements have ids like BlogPostCommentName or BlogPostCommentEmail, which get into $this->data array as:

[BlogPostComment] => Array
       (
           [name] => shannon
           [email] => shannon@home.com
       )

...and so on. But the recaptcha input's id is g-recaptcha-response, so it's not considered part of that set. This makes it difficult to validate the response. I don't know how to solve that yet, but anyway, that's where your posted data is probably ending up.
