Cakephp Google RE Captcha not posting data - php

Question

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?

Answer 1

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.
