ContentBox Clustered Captcha

This module will add Captcha Security to your comment forms that can be distributed in a cluster as it leverages the CacheStorages module.

Installation

Just use CommandBox: box install contentbox-captcha, then visit your ContentBox administrator and activate the module in the Modules section.

Usage

This module will automatically add Captcha security to your comment forms. However, you can also leverage it to add it to any form.

Displaying the Captcha

You can display the captcha by using the following code:

<!-- Display Captch using /contentbox-captcha entry point -->
<img src='#event.buildLink( 'contentbox-captcha' )#' />

<!-- Field For Input -->
#HTMLHelper.textField(
    name			= "captchacode",
    label			= "Enter the security code shown above:",
    required		= "required",
    class			= "form-control",
    groupWrapper	= "div class=form-group",
    size			= "50"
)#

Validating the Captcha

You will need access to the captcha service which is registered in WireBox as CaptchaService@contentbox-captcha. You can inject it in your handlers like so:

property name="captchaService"	inject="id:CaptchaService@contentbox-captcha";

You can then in the receiving action validate it using something like this:

if( !captchaService.validate( rc.captchacode ){
    // Captcha is invalid.
}
