Ok, first thing:

I'm using drupal6

 

When a user logins I want to load a page that shows some user stats.

The stats are taken from the users row.

 

Now in the php script will i still need to add:

mysql_connect('ip-address','username','password');

where username is the current user logged in?

 

Or can i just fetch the data, since the user has already logged in?

If i cant do that, How do i get the php script to recognise the current logged in user?
