fm:Form_Captcha


UNFINISHED

The documentation for this component is incomplete and should not be promoted to public viewing. While the documentation below should be correct, there may be better ways to demonstrate its use and some portions of the various CAPTCHA components should likely be refactored for better maintainability.

This component displays a CAPTCHA and a text box to verify that a human is performing some action.

The image is rendered internally by an fm:Form_CaptchaImage component. All attributes of the fm:Form_CaptchaImage can be assigned to the fm:Form_Captcha component and they will be passed through intact.

Example

<fm:Form_Captcha value="Enter the text in the image" />

Outputs

captcha
