[RESOLVED] using session values from different pages

lyros

Hi,
I'm new in php and generally in programming. I'm trying to use sessions for the log in. While logging in, a session stores a value for the username, and then the index page cheks if the username is still stored or is timed out.
The problem is that from the index page I can not use this session values at all. How can I get the values from the same session from different pages??

Thanks alot!!!

sessions work across multiple pages by default. I suggest reading some basic tutorials on sessions to learn how to use them instead of vaguely asking for instructions without posting code.

Some things to help while you debug session problems:

Verify that the cookie domain (you ARE using cookies to propagate the session ID, yes?) is set properly; if you're mixing [noparse]http://mysite.com and http://www.mysite.com or http://any_subdomain.mysite.com[/noparse], then you'll need to specify session.cookie_domain such that it applies to all subdomains on your domain (which by default it will not).
On each page, output the session ID (see [man]session_id/man) - verify that it does not change from one page to the next. If it does, then your session ID isn't being propagated correctly (e.g. incorrect session.cookie directive values, or perhaps your browser is refusing cookies/doesn't have them enabled).
[man]print_r/man is your friend - use it to output the $_SESSION array between pages to see what data it is being populated with.
If doing a header() redirect, try adding [man]session_write_close/man just before the header() call (and calling [man]exit[/man] after outputting said header never huts, either). I've personally seen instances where the webserver was slow enough to finish writing the newly changed session data to disk that the user's next page request came in just early enough to load the old session data (which might have been nothing), making it seem like the data was being lost.

Let me guess...you forgot to call session_start on both pages? Because sessions definitely work across pages (as long as they're both served from the same server, as well as some cookie requirements).

You may want to try out the live examples here:

There were several things I did wrong. One of theme was that I echoed some html before using header...

Thanks for the suggestions!!!
