Settings

• Provide a checkbox in the controlpanel to disable the form globally

• Add a H/Recaptcha/Norobots field depending on the installed 3rd party addon plone.formwidget.[h|re]captcha or collective.z3cform.norobots.

Captcha support

If you have installed plone.formwidget.recaptcha, plone.formwidget.hcaptcha or collective.z3cform.norobots it is automatically added to the form. In case both are installed, you can make a choice in the controlpanel.

You can install the packages by adding the extra_required to this package:

[buildout]
...
eggs =
    collective.contactformprotection[hcaptcha,recaptcha,norobots]

The settings mentioned above are all set in the configuration registry. See plone.app.registry how to set these values TTW or in a package profile.

Installation

Install collective.contactformprotection by adding it to your buildout:

[buildout]

...

eggs =
    collective.contactformprotection

and then running bin/buildout

Customizing Captcha vocabulary

The captcha settings is provided by a zope vocabulary with enhanced term objects:

class CaptchaVocabItem(object):
    def __init__(self, token, value, widget=None, validator_view=""):
        self.token = token
        self.value = value
        self.widget = widget
        self.validator_view = validator_view

If you have additional captcha addons or want to override the provided widget and validator view, you can override the vocabulary utility contactformprotection.captchavocabulary with your terms.
