checking uid

How do i go about getting the uid of the user and verify ?

Code:

if [ $uid != 'root' ] 
then 
        echo "You are not a superuser, please login as a superuser"
        exit1; 
fi

the above code doesn't work. can some guru please help me.
1. how to get the uid of the user ? i know by typing id but how to get the script to verify its a su?
2. how do i exit the whole script if he/she is not a su?
3. Is the above, able to continue the rest of the process if its a su?

-Thanks & Regards-
