.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A wrapper around Captcha::reCAPTCHA.
The reCAPTCHA fields aren't added to the form as \*(L"real\*(R" FormFu fields \- so
the values are never available via params, etc.
You can check that the reCAPTCHA verified correctly, by the usual methods:
\&\*(L"submitted_and_valid\*(R" in HTML::FormFu or \*(L"has_errors\*(R" in HTML::FormFu
.PP
This element automatically adds HTML::FormFu::Constraint::reCAPTCHA to
itself \- you should never add it yourself.
.PP
Although this is a subclass of HTML::FormFu::Element::Multi, you should
not call \f(CW\*(C`element()\*(C'\fR or \f(CW\*(C`elements()\*(C'\fR to try to add other fields \- consider
the reCAPTCHA element a black box.
