echo $captcha->get_html();

passed public key intenally in google get_html() using interface class.

How can i display captcha in both forms ?

Answer 1

Isn't it

echo recaptcha_get_html($publickey);

The API doesn't include a class, how are you using OOP style code?

Answer 2

Sounds like the javascript only renders this once per page.

One desperate solution might be to <iframe> one or both of the forms?

EDIT:
Create a page with the form in html, and access it with <iframe src="http://site.com/form.html"></iframe>

Set width and height attributes to desired sizes.

EDIT (2nd):
Well basicly you have a php file rendering and handeling the form data in the <iframe> . What exactly are you curious about regarding this technique?
