How to integrate a php code to the Admin Dashboard?

Hello everyone,

because my site is a carpooling site with departure country/departure city and destination country/destination city, i needed dynamic dropdown fields, such that by selecting for instance a departure country, all cities belonging to this country automatically appear in the departure city field. I found a code for that and every thing works very good. But when i try from the Admin Dashboard to have a look at an Ad, i can not see the dynamic dropdown fields anymore. My question is how to integrate the code such that the dynamic dropdown fields also available on the admin Dashboard.

Thanks in advance.
