Inser recaptcha php code into an existing complex php file


i am trying to configure recaptcha v2 on my website. I found the code on the internet, i am providing it below. I have done the client side work myself, however on the server side there is a [login to view URL] file done by the developer of a newsletter sending application that needs to include this code i found on the internet so that recaptcha starts to work. I am lacking the skills to integrate it so that all the current code keeps perfect functionality.

It should't be complicated for a coder,

best regards.



function post_captcha($user_response) {

$fields_string = '';

$fields = array(

'secret' => '6Lfg9V8UAAAAAJQmqjZnXa0AcmC4ISXD3twREuYN',

'response' => $user_response


foreach($fields as $key=>$value)

$fields_string .= $key . '=' . $value . '&';

$fields_string = rtrim($fields_string, '&');

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, '

[login to view URL]');

curl_setopt($ch, CURLOPT_POST, count($fields));

curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);

$result = curl_exec($ch);


return json_decode($result, true);


// Call the function post_captcha

$res = post_captcha($_POST['g-recaptcha-response']);

if (!$res['success']) {

// What happens when the CAPTCHA wasn't checked

echo '<p>Please go back and make sure you check the security

CAPTCHA box.</p><br>';

} else {

// If CAPTCHA is successfully completed...

// Paste mail function or whatever else you want to happen here!

echo '<br><p>CAPTCHA was completed successfully!</p><br>';
