"Success false" in Google Captcha implementation - php

Question

Again I came up with new google captcha question.
I have a view file with the following code :
<p>
<div class="g-recaptcha" data-sitekey="MY_SITE_KEY"></div>
</p>
Above code obviously under form element.
And after that,
In my controller, I am writing this as follows,
if ($this->form_validation->run() == TRUE) {
$recaptchaResponse = trim($this->input->post('g-recaptcha-response'));
$url = 'https://www.google.com/recaptcha/api/siteverify';
$data = array(
'secret' => 'MY_SECRET_KEY',
'response' => $recaptchaResponse
);
$options = array(
'http' => array (
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$verify = file_get_contents($url, false, $context);
$captcha_success=json_decode($verify);
#echo "<pre>"; print_r($captcha_success);die;
if ($captcha_success->success==false) {
echo "<p>You are a bot! Go away!</p>";
} else if ($captcha_success->success==true) {
echo "<p>You are not not a bot!</p>";
}
die;
}
But still it is not working form me.
Actually, I have registered my localhost url with Google account and I have different secret key and site key for the local and for the live one. But when I tried to use captcha, both live and local gives me same json output as the following one.
{
"success": false,
"error-codes": [
"missing-input-response"
]
}
Please suggest, how to overcome with this.
Thank You.

Answer 1

You are probably getting the error message, missing-input-response, because you are not passing the parameter "response" correctly.
Can you update your question with your code you are using for the call to the captcha API?
