Are you starting at Page2 with each browser?

hadinetcat · 06-04-2014, 04:21 PM

yes im starting with page2.php

It works for me in all three browsers.

hadinetcat · 06-04-2014, 07:37 PM

then whats wrong in my system, can you help me to fix it.

I'm not sure. I copied your code verbatim and it worked.
As stated make sure you start at page2 in each browser. Session variables are not common between browsers.

However, if cookies are not enabled in IE or Chrome then sessions will not work as your code is written.

i can see session file being created but its empty. any idea why

sundialsvcs · 06-06-2014, 07:55 AM

Sure ... the session cookies aren't being returned by the browser. The session-store has been created, the cookie has been sent, but it never comes back.

Activate the debugging facilities on Chrome and IE on the client side, and w-a-t-c-h the exchanges. You should see the host returning a set-cookie: request, and you should see the cookie value being stored. You should then see a request being sent to the same URL (note that "secure" and "non-secure" connections are distinct!), and the cookie-value should accompany it in the header.

"Guessing" is patently-useless.

Look.

i have figure out what exactly the problem is.
session_id(); not passing the same id number to the second page in result session file are created empty. Browser like IE and Chrome are not able to pick up session variable.

but not able to fix it.
any help regard this.

sundialsvcs, i ran IE debugging i can see set-cookie being store in /tmp folder, also i can see only received cookie, not send.

hadinetcat · 06-08-2014, 09:59 AM

Problem solved I had to change session.cookie_path in php.ini to / instead /tmp.
Thank you.
