Hi.I didnt find wordpress section so I am posting my question here .
i am creating a new "Bookings" custom post type in wordpress . And I already have a table in Mysql database set up where I am filling date from ,date to and the room name . My problem is that I want to have an option from the admin pannel to add new book to edit existing books etc etc. .But i dont know where(where to write php code for this) to start interacting with mysql to display that results in the admin panel .
