sessions or cookies is the way you probably want to go.
you could pass the variable around to each and every
form, but that is a pain in the ass, and extremely
prone to errors.
on the first page, where you check the user's ability to
use attachments, you could simply set a cookie
setcookie('cookie_can_use_attachments', ... );
and on subsequent pages, check to see if the variable
$cookie_can_use_attachments is set
or, if you plan to carry arounc more information from
page to page than just the user's ability to use attachments,
sessions will make your life much easier
best of luck.
