I would recommend that way of doing it
You need to have that user login. Create a table of users like:
userTab
username: varchar2
password: not sure of the name
position: varchar2
example:
in the table the following info will allow me to edit a field:
username: Deadeye
password: password123
position: Staff
Staff will give me the edit button. Your page will need to query for the position of the user and then either give them that button or not.
The following will not allow me to use the edit button
username: Deadeye
password: password123
position: member
