Populating a blank form from database?

[mysty]

Dreamweaver 8.0.0  PHP/MySQL
I've hit a snag and need a little help. I have a login page that checks the MySQL database for validation. Once the user is validated as a user, he goes to another page that lists most of his user info (name, address, etc). I am having trouble populating this page with the users info. Do I just use a recordset on the info page? If so, the only part I need help with is the DW filters. The second one just orders the results. The first filter has four blanks with something like: userID = cookie userID
If the userID is the PK, how do I set the four fields?
BTW - the info page has the same field names as the database field names.
