invoke script without user action

[keyser_Soze]

Nube warning!

I have a PHP script that does some calculations of user input. Under
certain circumstances, I
would like to have a popup on the user's computer. Since PHP can not
do this on the client, I
thought I would have PHP load a 'popup' page which would contain the
javascript to do the
popup.

1) Is this the right way?

2) if this is the right way, how can I invoke the action without having
the user selecting a link on
the 'popup' page.

Thanks for any insight.

Popups bad. Popups annoying. Avoid popups.

Just put the window.open call inline rather then inside a function or event
handler ... but the majority of browsers come with popup blockers which
will stop that from working (since the technique is/was so popular with
advertisers).

OK,

instead of a popup, I will direct them to an information page. When
they press ok on this page, I'll put them back into the normal flow.

Currently, the code does something like:

User inputs data -> (several pieces of info passed in form: <phtml
file>?=<some data>

I would like to do:
User inputs data -> show warning -> continue to next page.

How can I keep track of the <some data> along the way?

Include the data in the query string of the link.
Use a form.
Sessions.
Cookies.

Will I regret the fact that I used $_Session[''] data to do it?

To do what? http://www.safalra.com/special/googlegroupsreply/

(And using sessions could cause problems if the user happens to be working
in two windows/tabs at the same time and one workspace overwrites your
session variable mid-process.)
