Class Security_Captcha_Google

This functionality needs a site key that can be obtained at https://developers.google.com/recaptcha and the URL where to load the captcha script from (e.g. https://www.google.com/recaptcha/api.js).

It injects Google's ReCaptcha in a div that has to have the class "g-recaptcha" (only the first found div tagged with this CSS class will be used as the container for the captcha).

Config Parameter:

• SiteKey: The sitekey received from https://developers.google.com/recaptcha.
• DataCallback: The optional global callback method for when the captcha provides a result.
• DataCallbackCode: Optional code to be executed when the captcha provides a result.
• Script: The Google ReCaptcha script's address.
