Overview

modCaptacha was written by Geoff Bowers, Daemon for personal use. The code is released under Apache License 2.0.

modCaptcha is a FarCry plugin that adds a formtool field using the LylaCaptcha component for captcha validation. The formtool is attached to a boolean property in your content type.

Thanks to Peter J. Farrell et al for the captcha code.

Download

You may check out a read-only working copy anonymously over HTTP:
svn checkout http://modcaptcha.googlecode.com/svn/trunk/ modcaptcha

Installation

Copy all the modCaptcha plugin files to the plugin directory:

./farcry/plugins/modcaptha/*

Add modCaptcha to your plugin list in the farcryinit tag of your project's Application.cfm:

./www/Application.cfm
<farcry:farcryInit 
  name="daemon" 
  dbType="mssql" 
  plugins="farcrycms,modCaptcha,googleMaps" />

You will also need to add a web virtual pointing to the plugin webroot called /modcaptcha:

./plugins/modcaptcha/www --> /modcaptcha

(Alternatively you can copy the files in ./plugins/modcaptcha/www to a subdirectory called ./modcaptcha within the webroot of your project.)

Then simply reinitialise your application to make the formtool available.

How do I implement the captcha?

The formtool is used just the same as any of the formtools you may be familiar with in v4.0 – just create a boolean property and set the fttype="lylacaptcha". The captcha should be automatically created and managed.

Review the following sample code from the Daemonite blog

./packages/types/farBlogComment
<cfcomponent extends="farcry.core.packages.types.types" name="blogcomment" displayname="Blog Comment" hint="blog comment">

<cfproperty ftseq="1" ftfieldset="Blog Comment" name="subject" type="string" hint="Subject of comment." required="no" default="" blabel="true" ftlabel="Subject" ftvalidation="required" />
<cfproperty ftseq="2" ftfieldset="Blog Comment" name="description" type="longchar" hint="Comment description." required="no" default="" ftlabel="Description" />
<cfproperty ftseq="3" ftfieldset="Blog Comment" name="commenthandle" type="string" hint="Name or handle of poster." required="no" default="" ftlabel="Name" />
