title: Recaptcha missing-input-response
body: <p>I have a problem with google reCaptcha.</p>
  <p>Here is my php code:</p>
  <pre><code>$secret = 'SECRET_KEY';
              $response = $_POST['g-recaptcha-respone'];
              $remoteip = $_SERVER['REMOTE_ADDR'];
  
              $url = &quot;https://www.google.com/recaptcha/api/siteverify?secret=$secret&amp;response=$response&amp;remoteip=$remoteip&quot;;
              $result_json = file_get_contents($url);
              $resulting = json_decode($result_json, true);
              print_r($resulting);
  
  if($resulting['success']) {
    //Success
  }
  </code></pre>
  <p>input of print_r is: Array ( [success] =&gt; [error-codes] =&gt; Array ( [0] =&gt; missing-input-response ) )</p>
  <p>How to solve this problem?</p>
  <p>Thanks for answers</p>
