The likest solution for you problem seems to be session. Start a
session on the first page. On the next page validate every
variable and if all went ok, bind it to the current session.
Don't forget to make a page counter so no one can jump easily
from page one to four. After your last form action and validation
put all your data in the database and you are done.

If you don't know about session, try reading the following
http://www.php.net/manual/en/ref.session.php .

kind regards,
        Markus
