Can anyone explain or show a reference for the use of
pinged column in the wp_posts table? It seems that my Googling skills have failed me.
I wanted to do an experiment using the
pinged column to save the
term_id of a term that is related to this post record.
I know that the proper way is to use custom field instead, but I wanted to reduce the mysql
inner join in the WP_Query calls.
Thank you in advance.
