I presume that id is a primary key with auto_increment.
Once you've saved the record use last_insert_id() to return the newly
inserted PK. Then you can redirect to your next page using that
information.
Just wondering, is that safe? More than one person can subscibe at the
same time. Can't one get the wrong id then?
No, if the last insert id is called during the same connection. It works per
connection, even if there are two concurrent connections, the function
returns the id that was inserted during that particular connection, the
other connection does not affect even if it does insert another record at
the same time. This applys at least to mysql's mysql_insert_id() function,
and possibly to other rdbm's as well.

Why not use sessionvariables for the information u want to transfer?
Yes, it can be done with session, but a session requires a cookie, and not
everyone allows cookies. Cookies, we don't need no stinkin' cookies. Just
put it in the url and it works for sure...
