New To PHP / New Project

[Spacer]

This is my first project using Sessions.

I'm not sure which information to actually store in the $_SESSION variable, and what to leave in the database and just call it through a query when needed.

Username will be stored in the session.

Other values stored in the database in the Users table will also be needed often...would I store then in the $_SESSION variable...or would I just leave them as is and call them seperately when needed?

Thanks in advance,

Spacer.

I would store anything that is unique to that user in the session and will be needed multiple times. For myself that is user name, permission level, and usually a unique identifier for the users account.

Reasons are, the name you may want to have it displayed in every page they load. The permission level they are set at can be used to hide or show links and/or give or deny them access to some pages. And the record number as that could be need if they wish to change personal info or if you want log that users activity as they visit different pages.

I guess my answer is a both and. Anything that is going to be needed more than just once as the user goes to each page on your site may be best kept in the $_SESSION. Otherwise if it a one time thing have the unique identifier grab it when or if it is needed.

Thankyou Kril.

This also gives rise to another question:

As the script runs, the data that would be held in the $_SESSION variable that is loaded then the user logs in will be changed as the scripts run.

Will simply refreshing the page or nagivating to another page refresh the $_SESSION variables with the new data, or will it have to be called again?
