I'm well aware of Views Or; I'm looking for something that would do a Conditional Filter. Example:
I have a CCK field called showcase. If there is any node with the showcase field set to TRUE then I only want to display nodes of that type. But if none of my nodes have showcase selected then I would like to ignore this filter to still display nodes in this view. View has a random sort; also using sorting to do filtering doesn't seem like the correct way to do this.
Has anyone created a views plug-in like this?
