How can I display existing content in custom fields? In my booking site project I would like to display destination info depending on the chosen hotel. I want to manage destination info in one place (post), so that changes reflect automatically everywhere.
Basically this - in the CPT, under destination info, I would like to have checkboxes with destination names. If I click Toronto, on the frontend there should be displayed the Toronto destination info (Toronto post). And when I update Toronto post, the change is updated in all Toronto destination infos.
