Problem: session_id changes from page to page

[coachman]

It appears that when I use sessions between pages, if I redirect from say, page1 to page2 with a "header('Location:...')" statement, it sets up a new session_id in page 2 and thus ignores all the $_SESSION array from page 1. It is as if I have two different sessions going, one for each page.

On the other hand, if I go from page 1 to page 2 with a link like "<a href="page2.php">Click</a>", then it works just fine. The session_id carries over from page 1 to page 2.

Question: In the first instance, am I doing something wrong? How can I make sessions work with redirect headers such that the session_id stays the same?

Any help or suggestions would be much appreciated. :queasy:

Can you give us an example of the URI you're redirecting them to in the Location: header? If you're crossing subdomains, it's likely that you'll lose the session (if you use the default session settings - this can be changed).

Also, what is the value of the session.cookie_path directive (look in phpinfo())?

EDIT: It might also help if you show us some sample code using the header() redirect that's giving you problems.

Try doing a [man]session_write_close/man right before you do the header() redirect. If that does not do the trick, try also adding the following right before the header():

header("Set-Cookie: PHPSESSID=" . session_id() . "; path=/");
