Session_id not persistant between pages!

Copy linkTweet thisAlerts:
Feb 12.2006

Hi all, Need a little help, its probably simple and i’ve just missed something. Im trying to save an SQL string to a PHP Session, so i can be called again to run at a later time. However, initially i set the session and it gave me nothing when i echoed it. Now i’ve realised that the session_id is changeing with each page.. The session_start is located in an include and is obviously working as i’m getting a session_id each time. However i never have the same one between refreshes! Its on a shared web host so i can’t directly access the PHP Session Paths folders or PHP.Ini directly! Help…..

A suspicion of mine was something to do with browser caching and accepting cookies, but a 100 or so different searches on google turned up no answers…..

At the moment, i simply have a top include that has session_start() and echo session_id(), which is before head tags.

@bathurst_guyFeb 12.2006 — I use this at the start[code=php]if (session_id() == ""){
session_start();
}[/code]

@xyligoauthorFeb 12.2006 — Thats still creating new session_id()'s with each refresh and link clicked throughout the site. If tried also changing the session expires with ini_set but this had no effect! Thanks anyway!

@SheldonFeb 12.2006 — [code=php]
<?php
session_start();
$_SESSION['sid'] = session_id();

echo("You're session ID is "". $_SESSION['sid'] ."".");
?>
[/code]

@xyligoauthorFeb 12.2006 — I put the code into my include yet the session_id still changes with each refresh. [URL=http://www.xyligojobs.com]Site here[/URL] shows whats happening. Thanks.

@SheldonFeb 12.2006 — Did the second suggestion help?
Copy linkTweet thisAlerts:
@xyligoauthorFeb 12.2006 — I'm closer to sorting it, will post a full solution when i do, it seems to be something to do with Top include....


** EDIT ** SORTED

using this code from the php.net site, i managed to work out that it was trying to do too many things with sessions before it had finished, so it just created a new one. either way, works now.

[code=php]if (isset($SessID)){ session_id($SessID); }
session_write_close();
session_start();
header("Cache-control: private"); // IE 6 Fix.
setcookie("SessID", session_id(), time() + 3600); [/code]

Thanks all for your help

@xyligoauthorFeb 12.2006 — Yeah, the 'isset' part did, i checked up on the php site read a few bugs lists and found the session_write_close() part. All seems to be happy now. Can't beleive i've been messing for nearly 8 hours with that!!! all just to save the last search so it can be returned to!!!

Many thanks Sheldon!

***************************

After it sorted itself out it seems to have reared its ugly head again.. This timeill include the source from the top header. I have removed all other session related coding from the rest of the pages..

The site acting up can be found [URL=http://www.xyligojobs.com]here[/URL] although i have reason to believe this is a client/server specific problem. the source is below

[B]top.inc.php[/B]
[code=php]<?php
if (isset($SessID)){ session_id($SessID); }
session_write_close();
session_start();
header("Cache-control: private"); // IE 6 Fix.
setcookie("SessID", session_id(), time() + 3600);
echo session_id();
include("globals.php"); ?>[/code]
