This function was added in version 20090614 of the Beta, to help abstract away some of the nagging details of adding CAPTCHA spam detection script to a POST form. The function should be included at the top of your POST forms that contain a reCAPTCHA. It displays an appropriate error message if the user fails to enter the CAPTCHA properly. Usage:

The default error message is Sorry, the CAPTCHA (image verification) was entered incorrectly. Please try again. This message always in English. To override it in the language of your choice, to change the wording or style the content, you can just pass in a string as the parameter, containing whatever HTML content you want. e.g.:

That will then embed that HTML and error message into the page.

For more information on reCAPTCHA, see the documentation on the ft_api_display_captcha function.
