reCaptcha.net HELP

Hi

I have free web-based email in my site, and i offer free emails to my users
But the sign up page did not included any Captcha,
And yesterday somebody spam me by signingup for more than 300 user,
Anyway I get an account from recaptcha.net to use it in my signup page
But the problem is that i cant find the signup page in my server
For example when i click on Sign Up in my site i see this address in my IE
http://mydomain.com/index.php?func=signup
I searched in my server and i just find an HTML page called signup.html
and i saw the signup page there,
I tried to page the recaptcha code there, but it say that it work only in PHP
page and not HTML

Anyone can help?
Where i can find this page?

Thanks

 

The signup page must be in index.php.
Try to look for something like this:

if($_GET['func'] == "signup")
{
  //the signup page
}

Code (markup):

OR

switch($_GET['func'])
{
 case 'signup':
  //the signup page
 break;
}

Code (markup):
