how to do this simple thing

i wanna achieve this.

suppose the person who has logged in is admin then the IP option is seen otherwise not..

My apporach would be to include this code in a php file

if (user== admin )
then execute template 1
else execute template 2

where template 1 and template 2 are basically the same
except for the IP option.

am i right ???

Any other approach ??
