Is there a way to count the amount of empty fields of a post (or the fields of a plugin as they relate to the different)?
For example, I have 1,500 posts on my site. Each post has important fields (information) needed for the proper functionality and user accessibility (i.e. city, state, zip code, address, etc), but not every post has all of these fields filled out.
So what I want to do is know how many posts are missing certain fields. For example, how many posts are missing the city field and so forth. Is there a plugin or a function that can count the amount of fields are missing?
I would really appreciate any help or advice with this. This would be very helpful for multiple reasons.
Thanks in advance,
