Invisible Recaptcha

I can't seem to find a proper implementation of invisible recaptcha anywhere, all libraries I tried just fail to verify switching to invisible. I noticed that in normal operation the recaptcha asks me to verify using various images, I suspect this is not properly handled in any of the libraries I tried. Is there a working library for v2 invisible recaptcha anywhere that handles this properly or how do I add handling re-verification to it?

Personally I would use the new V3 instead, here are a tutorial for it:

Or use their library:
https://github.com/google/recaptcha

I tried integrating that library into codeigniter, but it would just give me back captcha failures all the time. I put the captcha validation in the controller, should that be directly in the view instead?

You will need to implement two parts, one in view:
https://github.com/google/recaptcha/blob...scores.php

And one in controller:
https://github.com/google/recaptcha/blob...verify.php

I guess you got it working?

I prefer Honeypot, invisible, empty field.
