Introduction

plone.formwidget.recaptcha is a z3c.form ReCaptcha widget for use with Plone.

It is a z3c.form re-implementation of the collective.recaptcha package original written by David Glick.

Buildout Installation

Add the following code to your buildout.cfg to install plone.formwidget.recaptcha:

[buildout]
...

[instance]
...
eggs =
    ...
    plone.formwidget.recaptcha
    ...

ReCaptcha setup

There is a control panel at http://path/to/site/@@recaptcha-settings to configure the Addon. Google provides a set of test keys, that can be used to try out the recaptcha form and documentation at https://developers.google.com/recaptcha/docs/faq.

Site key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI

Secret key: 6LeIxAcTAAAAAGG-vFI1TnRWxMZNFuojJ4WifJWe

To actually use the service, you must obtain a site key and secret key from developers.google.com/recaptcha

Usage

See the demo folder inside the distribution for an example usage.

Supermodel

You can add a captcha field in an XML model by adding something like this:

<field name="captcha" type="plone.formwidget.recaptcha.ReCaptchaWidget">
  <title>Solve Captcha</title>
  <description></description>
</field>

Upgrade to API v2

plone.formwidget.recaptcha 2.* uses V2 of the reCaptcha API. Users upgrading from plone.formwidget.recaptcha 1.* will therefore need to generate new keys as global Keys are not supported in the V2 API.
