redirection query

[damon2003]

hi,
I have a question about PHP redirection. I have a cancel button on my page. When pressed I want to run a script that will unregister some sessions and then redirect to a specific page.
I thought about this:

session_unregister('completeCustOrders');

header(location: http://)

the problem is doesnt the header(location: http://) has to be right at the top of the page. Are there any other ways to redirec to a page

No, that is the only way. I don't see the problem, though. Why not just put this at the top of the page?

Hi,
at first I though that nothing at all could be placed above the header.
So its just HTML that cant be placed above the header?

Correct. As long no output has been sent to the browser, it will be fine.
