How would i write code for User and Admin Dashboard with their details

Question

User Dashboard for students
Admin Dashboard

Answer 1

Which language you are using?

Do you know how to make login? If you don't, you need a database and a backend language. Store user data and permissions in the database.
After user login, set cookie and write permissions in the cookie. PHP is an example backend language
https://www.w3schools.com/php/php_cookies.asp

Make different page for admins and write PHP code above html codes. Check permission from cookie. If they are not admin close the page with php codes.
