Conditionally show/hide collections with Commerce Kickstart
since some days I am trying to hide some collections from people who are not logged in as authenticated users. Or in other words: Some collections should only be visible to people who have at least the role "Authenticated User". I already added a field "authenticated users only" to the taxonomy vocabulary "collection".
The problem is that I couldn't find a way how to filter the items that are being shown to the users.
I tried multiple ways like the module "content_access", plugins like "views_plugin_access" or just hooks like "hook_node_access".
"content_access" seems to be the wrong way.
With the views plugins, I don't know how to get the data of the current node and its collection vocabulary.
I would be very thankful if anyone could put me in the right direction. I am using the current release of Commerce Cickstart.
Thank you in advance
