Hello,
I'm new to Meta Box so forgive my naivity. I'm trying to create a page that allows the user to enter exam details, such as the start time, date, end time, date and exam name. I also want an exam location field to show in a dropdown or select box, that is populated by the contents of another custom post type called Exam locations, which has a custom field called Excam location.
How do I get the dropdown/select field to populate from the exam location custom field in another post type?
.
