A Plone add on to simplify form confirmation by e-mail.

PloneFormGen, confirmation, email
pip install collective.confirmableforms==1.4.3



This product adds a new emailer for Products.PloneFormGen. Our emailer is based on the default PFG one, but will first send an email to the person who submitted the form so he can confirm his email address.

This products relies on PloneFormGen and collective.depositbox to store the data waiting for validation.


This has been tested with Plone 4.3 and PloneFormGen 1.7.


Add collective.confirmableforms to your buildout and install it via Zope quick installer or Plone add-on control panel page. First install PloneFormGen itself, then collective.confirmableforms.

Form setup

  • Add a PloneFormGen form.
  • In this form, add a Confirmed Mailer Adapter.
  • On the Confirmation tab of this mailer, set a plain or html text that includes [[confirmation_link]] to display the confirmation link.
  • Remove any other action adapters from the form, especially the default Mailer Adapter, otherwise the other actions are executed anyway, even when the form has not been confirmed via email yet.
  • You probably want to edit the thanks page and say here that the user will be getting an email and should click on the link there.
  • You can add a second thanks page to say that the email has been succesfully confirmed. Edit the Confirmed Mailer Adapter and select this as thanks page on the confirmation tab.

How it works for the visitor

  • A visitor fills in the form and submits it.
  • The thanks page of the form is displayed.
  • The visitor gets an email with a link to confirm his input.
  • The visitor clicks on the link.
  • The normal part of the mailer kicks in, sending an email to an admin, or however you have set it up. This works the same as the default mailer.
  • The visitor sees the thanks page that is configured in the Confirmed Mailer Adapter.
