Allowing users to view certain data entries

So I am working on a database for my University. This is my first time using Omeka, and this is my senior project so I am learning a lot of this technology now. I have just successfully installed 2.0 on a Ubuntu VM (woohoo)but I need to meet a certain requirement that my client needs.

There are certain data entries that they don't want to be available to the public, or certain users. For instance they do not want the public to be able to see the field 'Value of piece' or 'location' for obvious reason, but they do want users like admin to be able to log in and view those data entries.

What would be the best way to do this, or is there a way to do it and I am just missing it. I saw a topic similar to this that was posted 3 months ago, but I think that was before 2.0


I am interested in this too, so I made a similar post. Same issue, which mostly concerns items which may have copyright restrictions and therefore require user validation in order to see and use.

Can anyone give any incite into this?

I think the code would be something like this
if ($user->isAdmin() == true) { // or just use if ($user->isAdmin()) -- shorthand works too
// Do something here
else {
// Do something else

I just have no idea where to put it.
