Quite easy, you need to tweak your default code as it follows.
Javascript code:
1 2 3 4 5 6 7 | // JavaScript Document var ReCaptchaCallback = function() { $('.g-recaptcha').each(function(){ var el = $(this); grecaptcha.render(el.get(0), {'sitekey' : el.data("sitekey")}); }); }; |
Google recatcpha cdn:
2 | <script src="https://www.google.com/recaptcha/api.js?onload=ReCaptchaCallback&render=explicit" async defer></script> |
Your form code with the recaptchas:
3 4 5 | <div class="g-recaptcha" data-sitekey="enter the key"></div> <div class="g-recaptcha" data-sitekey="enter the key"></div> |
Create a blank page with the code so you can see first how it works.
