show cookie popup if the cookie configuration has changed, retain existing settings

[medarob]

Suppose I configure the extension to have third party cookies as options. The user selects the cookies he wants to allow/disallow and saves the state. The cookies are set and the cookie pop-up disappears - that's what a cookie is for. After a certain time a new third party cookie is added. Now the cookie popup needs to be displayed again but currently that does not work. As the user, you wouldn't know if there is a new cookie or if something has changed in the cookie configuration.

If you select "Accept all cookies" when you first enter the page, would newly added cookie options be automatically accepted at a later date?

The user should see the pop-up again when changing the cookie configuration and existing settings should be retained.

Yes, use case acknowledged.

We should save a hash over the configuration in our consent cookie.

I am not yet fully clear with how to implement this.

What kind of configuration change should trigger re-showing the consent?

• any (easiest to implement)
• any shown cookie (tracking object item) (indicated by tracking object item key https://docs.typo3.org/p/dmind/cookieman/master/en-us/Configuration/Reference/Index.html#trackingobjects-tracking-object-key-show-tracking-item-key), ignoring texts and other tracking object item information
• any tracking object (indicated by tracking object key)

Or should we just add a setting like e.g. consentConfigurationVersion - so the integrator would change that and if existing cookies don't match it we show the consent banner?

I think a simple plugin.tx_cookieman.settings.consentConfigurationVersion is the way to go here.

how can i implement plugin.tx_cookieman.settings.consentConfigurationVersion? What are expected values? I dont see this in documentation or in typoscript of extension

[jonaseberle]

It is not implemented yet. Somebody could do it.
