trying to solve a simple problem, I think.
in table wp_ / wp_usermeta
I have the following fields and info.
Assume I am on a page, user is logged in, I wish to show this user who else has marked a post for "watching". I use wp-favourites plugin to allow user to watch a post (or item, in my case).
the number '342073' is a $post_ID, for example.
how do I get get every user_id where meta_value contains $post_ID as array.
then resolve array into user_ID as nice name,
wish to return list of users as comma seperated text.
such as "jeff, john, and Bill" are watching this post.
