function uc_wishlist_user in UC Wish List 6

Implementation of hook_user().

When a user logs in, any products on the wish list associated with the current session are moved to the newly authenticated user's wish list (or if that does not exist, the anonymous wish list is assigned as the user's wish list).

Also, provide a link to the user's wish list from the user's profile page.

File
