Re: [PHP] Sessions Header PROBLEM again!
Hi, thank you for your attention
This is only a sample to understand how the session work, in order to use them
in a more complex web applications
The goal is verify how to pass the var $count through each of the three pages
by the php session function
Particularly, when as usually, a client has the session/cookies disabled
Call First.php $count=1
Go to the Second.php, here $count would be always = 1 (but with session
disabled $count stay not defined)
Go to the Third.php == always $count=1 (but with session disabled $count
stay not defined)
Go to the First.php $count=2 (with session disabled $count is always =1)
and go on
1) Ok is a writing mistake
2) I delete the hidden variable 'count' in the form, but the pb is not solved
yet
3) The final php script has more fork I had to use header(Location...)
4) Yes!!! Is only a sample :-)
5) Deleted the hidden var
Why with session enabled all is OK
and with session disabled all is KO???
Bye bye
Alessandro

Don't know offhand what the problem is, but a couple thoughts:
1. Why are you using session_name(mysession) instead of
session_name('mysession')?
2. Assuming you have register_globals on, you're trying to pass $count
both as a session variable and a post variable. One of these is going to
get overwritten by the other if I'm not mistaken.
3. Why not have the page 1 form action point directly at page 2 instead
of being redirected through page 1? Do posted variables follow a
redirect?
4. If posted variables do follow a redirect then page 1 will see that
$submit is set and redirect to page 2, which will redirect to page 3,
which will redirect to page 1, etc... Can you get an infinite
redirection loop?
5. The form on page 1 includes a hidden count variable, page 2 and page
3 don't.
What happens when you run this?
