PHP giving specific item access to admins

So I have this food ordering system where each admin uploads his or her food from the backend and users can browse through those food from the frontend, a simple program. But what I want is that an admin should not be able to view or update the food from another admin as right now any of the admins can view and update all the food that are uploaded on the backend. What I want is only a specific admin only viewing and updating his or her added food items.
Attached below is the snippet and picture of the food view and update page where it displays all foods and can update them.
FYI the code is in PHP and the backend is SQL in phpMyAdmin
Please do let me if there are any confusions in my explanation.
