reCaptcha - Dreamweaver CS3 html/php

[Lexie \m/x]

Hi guys

I'm using Dreamweaver CS3 to create a website complete with online
enquiry form. The form has been made using html & I've also done the
php file to go with it to make the form work. I am new to php though.

I would like to add reCaptcha to the bottom of the form to be entered
before hitting the submit button. I've registered with reCaptcha &
have my Public Key & Private Key. I need help with what code needs to
be entered.

1) The html code to display the reCaptcha widget within the form

&

2) The php code to make the reCaptcha work

Any help would be greatly appreciated.

Cheers

Lexie

again." .
"(reCAPTCHA said: " . $resp->error . ")");

With the code above, I have successfully displayed the widget,
however, when clicking submit I get this error message "The reCAPTCHA
wasn't entered correctly. Go back and try it again.(reCAPTCHA said:
invalid-site-private-key)"
