It is actually wordpress cron job that I needed.
WHAT IT HAS TO DO
1) Duplicate everything from the latest post from post type updatelist, and modify its post_date to current server date and time, and of course with newly generated post id which is unique, and also modify post_title to current server date in the format of dd/mm/yy, with published status
2)Duplicate from a few post types, duplicates all fields including meta fields,where the posts last modified or created date=one day before server's date, and also modify its meta values in postmeta in sql, the meta_value = post id of the newly created post of updatelist(which i assume you can set it as latest post of updatelist<as you created the post before you execute this function)
I can provide you the login to the sql for you to see it for clearer picture.
I'm sure that you can finish it within hours maximum.
I can pay COD, or I can lock the money in here.
I'm paying for USD20, no high bidders please.
