Sessions.. grrr

cabadam

Ok, I am having a bit of trouble understanding sessions.
I am using Apache w/ the PHP module.

How do I maintain them from one page to another?
In the initial script where i started the session, it works ok (i think)
but then if I redirect to another page, $HTTP_SESSION_VARS comes up undefined.
What point are storing variables if you can't keep them from one page to another???

If anyone can help, I'd appreciate it.

Thanks,
Adam

hi Adam,
forgot about the $HTTP_SESSION_VARS ... all u need to do is to edit the php.ini file located in ur windows dir. then go to the [session] section ... then update the line session.save_path to be something like session.save_path = c:\temp
then set the session.auto_start to 1 ....

now save the php.ini file ... everything is now working just fine 🙂

Don't set the session_autostart(). If you do, you won't be able to ever send any custom headers again (you can't redirect) which is a major pain in the butt.

What you need to do is make sure you pass the session_id to the next page so that PHP can identify the session and open it from disk.
The easiest method is to make PHP use cookies to store the session ID on the client side.

Read the manual section about sessions (twice)

read it more than twice... just confused myself.

I tried to get what I am doing working just by using cookies myself and that didn't do much at all 😛 So I was told to check out sessions and now they being a pain too

I guess I could try the autostart. If I ever need to redirect, I could flip over to javascript real fast 😛
