i have a custom post type called books with fields genre,author,bookname i want to dynamically create the link booklink based on the data in the 3 above field and put this booklink into the database for the post on publish or update.
how do i do it
<?php $genre = get_field('genre'); $bookname=get_field('bookname'); $author=get_field('author); $booklink="http://mybooks/".$genre."/".$author."/".$bookname.".com"; ?>
i donno how to get this booklink field created and updated with the data in the database for each post on publish/update.
