Quintagroup Plone Captchas

The Captchas products story started back in 2006 with qPloneCaptchas Plone product which supported Plone versions 2.0.x, 2.1.x and 2.5.x.

Later it was refactored into quintagroup.plonecaptchas package which supported Plone versions 3.0.x-3.3.x.

From version 3.0 and on quintagroup.plonecaptchas goes though another refactoring:

  • the standard Plone customizations (Join, Send this page, Contact Us, Reply) are staying in quintagroup.plonecaptchas
  • the captchas core rendering and validation functionality are factored into quintagroup.captcha.core package

We are adding the following three packages to the stack:

All the stack is set up as dependency for quintagroup.plonecaptchas, so you just need to mention them in your buildout to get all captcha packages.


Quintagroup Captcha Core allows configure captchas on your Plone site: its size, color, etc. After its installation you'll see Plone captchas setup option under Add-on Product Configuration in Site Setup.

Here you can select what kind of captchas you want to appear: either static or dynamic. In case you select dynamic captchas, in the dynamic captchas image setup options you can configure captchas look by using different font sizes, background and font colours, period, amplitude, random values. As a result your captchas field can look like the following:

quintagroup.plonecaptchas adds captcha support to Plone, it works together with quintagroup.captcha.core. With these products installed captchas will be added to Plone's Send this, Contact Us (/contact-info) forms, and Plone's default discussion mechanism: Add Comment and Reply forms.

Join Form

quintagroup.plonecaptchas does not automatically plug to Plone's default registration (/join_form). You can make captcha plug to Plone's Join form via Zope Management Interface:

  • Go to portal_setup/manage_importSteps
  • in Select Profile or Snapshot drop down menu select Plone Captchas Join Form for plone 3-... according to the Plone version used on your site, e.g Plone Captchas Join Form for plone-3.3

  • Move to the bottom of the page and press Import all steps
  • Captcha will now be applied to the registration form.


quintagroup.captcha.pfg (former qPloneCaptchasField product) allows adding captcha field to the forms, created with PloneFormGen?.
