Talking about DRUPAL 7, I've found some modules that manage automated backreferences between content types, but these are based on nodereference fields: i need something based on TERMREFERENCE.
I'll try to explain better:
I've a vocabulary (i'm talking about taxonomies, NOT content types) and I've added a termreference field type pointing to the same vocabulary. The scope is to have a "see also related terms" feature when someone is viewing a taxonomy term page.
What I need is a backreference between terms, so, when I add a term B as term reference on term A, automatically term A is also attached to term B as termreference itself:
term A -> Term B
Automatically I need a term back reference:
Term B -> Term A
How can this be done?
Thank you very much!
