HTTP is stateless. Each time a user requests an HTTP resource provided by a script, that script is run from scratch. If you want to make data persistent from one HTTP request to another, you either have to get the browser to pass it back (by encoding the data in the URL (typically with the query string, or (with the help of a form) in a POST request - either way it can be accessed with the param method of the CGI module), or by storing it on the server and asking the client to pass a token about (typically in a Cookie) to identify which set of data belongs to the user (this is usually done with sessions: http://search.cpan.org/~sherzodr/CGI-Session-3.95/Session.pm )
Hi,
Thanks a lot David, I didn't know about that. I'll get that module and try to do.
Yours,
