google recaptcha - Not a Robot

[admin]

 Just copy and add red & blue code

 Add this before end of head tag

<script type="text/javascript" src="https://www.google.com/recaptcha/api.js"></script>
          <script type="text/javascript">
      var onloadCallback = function() {
        grecaptcha.render('html_element', {
          'sitekey' : 'YOUR SITE KEY'
        });
      };
    </script>
</head>

Next add this after form tag

  </form>
                     <div id="dmxReCaptcha2" class="g-recaptcha" data-sitekey="YOUR SITE KEY"></div>
                      <script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit"
        async defer>
    </script>

Next add this after html tag

</html>
<script type="text/javascript">
   function my_button_click_handler() {

   var recaptcha = $("#g-recaptcha-response").val();
   if (recaptcha === "") {
      alert("Please check the recaptcha");
      return false;
   }
   return true;
};
</script>
