I'm building a website on Wordpress 4.2. We're having some trouble with some code, and we need outside help.
I'm attempting to create some functionality for my site that will decrement a custom field by the value of 1 each 24 hours. It will run as a Wordpress cron job (not a real cron job). The custom field is wpcf-engine-days-to-go and the post type is 'engines'.
