sessions?

[Anon]

hey, i've been working with PHP for about 6 months now, and i haven't had to do too much with sessions, but now i have to.

in this case, i need to register two variables, $social_security and $dateofbirth for a registration form.

i insert them into my database with one php document form and then head over to another php document to enter in all the information for the registration form. to be able to grab the right registration information from the first document, i need the variables from the first page so my SQL query will grab the right row from my table.

anyone know how to do this, or has done this before and has a solution, or a smarter means of going about doing this?

On the first page, start off with:

<?php
session_start();
session_register('s_social_security','s_date_of_birth');

Then set the values of $s_social_security and $s_date_of_birth appropriately in the normal fashion (they're ordinary variables).

On the second page:

<?php
session_start();
session_register('s_social_security','s_date_of_birth');

and $s_social_security and $s_date_of_birth now have the values they were given on the previous page.

Incidentally, I've added the "s_" in case you've called the form fields social_security and date_of_birth. Otherwise the values from the two different sources (the form versus the session) will probably end up stomping on each other sooner or later.
