Inserting records into database

Hi all,

I have created a multiple page survey form which collects a user's opinion. The Userid field is primary key and is auto_increment. How do I ensure that subsequent questions answered are inserted into that particular user's record?

in other words, how do i get the primary key carried over to the next page for current user filling out the survey....

thanks.

Depends if you want to use php you can use mysql_insert_id() (if you're using mysql) or directly from the query you can use the mysql function last_insert_id()
