问题
I am following this Invisible ReCaptcha doc on my php website: http://www.pinnacleinternet.com/installing-invisible-recaptcha/ everything works well. but while implement on multiple forms in a same page then Captcha only work on first form and not sure what’s happening with the second form, I curious to know how its work with multiple forms in a single page. Or anyone please suggest a working doc for multiple forms?
//this is @Geordy's javascript portion modified according to jquery.validate
<script type="text/javascript">
$().ready(function() {
var demo1Call = 0;
var demo2Call = 0;

pwcheck: true,

I used Unofficial Google Invisible reCAPTCHA PHP library in this program and you can download it from https://github.com/geordyjames/google-Invisible-reCAPTCHA . If this method doesn't work for you please comment below.
