I'm creating a website for an art gallery.
For each artist I use a post that is tagged with his/her name.
For each catalogue I use a post that is tagged with the name of the artists involved in the exposition
On the right of the artists page I have set a menu where there is an item called "catalogue". I would like this item to link to the catalogue post conditionally, I mean that the catalogue post should have the same tags of the artist post...
I can't find any plugin for that, any suggestion on how to do it?
