new session always created on session_start()

[smudge]

Hi everybody,

I am moving a php site to new hosting, and what was working fine on the old hosting is now broken on new hosting. The problem is that session_start is always creating a new session, even though one exists. I can see that the cookie is created just fine locally on login, and the matching session file is created on the server. But once I go to a new page, my checklogin() calls session_start which returns a new empty session, and I am automatically logged out.

Here is how I create the session during login:
[PHP]if ($rs->RecordCount( ) == 1) { // Found a partner
session_start() ;
$_SESSION['real-usr'] = $usr;
}[/PHP]

Here is how I check that the user is logged in:

[PHP]function checkLogin() {
session_start() ;
if (empty($_SESSIO N['real-usr'])) {
echo "Session expired. Please login";
include("login. php");
die();
}
}[/PHP]

Note that it isn't shared hosting, so there shouldn't be a problem with other processes deleting the temporary session files. (Plus I can see that the temp files are still there.)

I am using PHP 5.2.2. Here is an exerpt from phpinfo()

If anybody can give me a hand, it would be much appreciated. I have been doing google searches all day and investigating different options, but haven't figured anything out.

Thanks,

i'm not 100% sure but maybe the problem is that your calling session_start() inside your functions.

session_start() should be the first line (after the <? tag), before any other code is used, and should only be called once per php file.

does that work?

Nope, that didn't fix it. It's still doing the same thing.

This may be an issue with the session cookie options. Try creating a cookie yourself and see if you get the same Host, Path, and Domain information in that cookie as you do in your Session cookie.

Thanks! That did the trick. The domain was missing a www and the path was / instead of \.

Glad you got everything working, and thanks for posting the solution so others may learn too.
Come back to the site any time you have a problem.

try that :
[PHP]if(!(session_id ()))session_sta rt();[/PHP]

why do you use it many times?
i woud use it once at first line
let me know if it works...
