Mysql Table to Form

Hi, I have a registration page for a online-store. When the customer registers, their information is put in a mysql table called userinfo. I need help with the next phase. When the customer checks out, they are taken to a page consisting of the shopping cart contents and a blank order form for them to fill in with name, address, etc.. I'd like to have password and username fields for registered customers at the top of the blank orderform. When they enter password and username and hit submit button, the script would check to see if they are authorized, and if so, the customer's information would automatically come from the userinfo table and pop into the appropriate blank fields. Again, the order form is already on the page and would be filled in manually by un-registered customers and automatically by registered customers. Anyone know if this is possible and how to do it.
Thanks, Vince

I'm working with Perl.

Well there are many ways to do this depending on how your are generating the order form. The most comman way is to pass a username or orderid cookie when they register, then when the order form is called, it retrieves these cookies, checks the username or orderid agaisnt the database and inserts the appropriate data. But as I say, there many ways to do this.
