[SOLVED] Trouble with Sessions and file locations

[_giles_]

Hi all,

I’m working on my first project with sessions, kind of getting stuck on what is probably a simple point. Would you mind correcting me? My understanding is that I can declare the session variables in an include file such as

<?php
  if (!isset($_SESSION["count"]))
  {
    $_SESSION["start"] = time();
    $_SESSION["count"] = 1;
$_SESSION["counthistory"] = 1;
$_SESSION["lastpage"] = 100;
  }
  $_SESSION["count"]++;
?>

and that I can then access the session from other files such as :

<?php 
require_once "admin.inc";
session_start();
echo "session_id() is : " . session_id();
echo "</br>";
echo $_SESSION["count"];
?>

this is partly working, in that I can  return the session_id, but I get a “Undefined index: count” with the count parameter. what am I doing wrong?

I’d appreciate any help you could give me.
Thanks in advance
Giles

the session_start() must be above where ever you are using any $_SESSION variable.  If you are using sessions, it is generally safe to ALWAYS MAKE SESSION_START() THE FIRST THING IN YOUR SCRIPT.

thanks for the quick response ... works a treat!

guess the only thing leaving me a little puzzled is why do ALL the tutorials I've been working on put the include files at the top seemingly without getting into trouble? I thought I needed to put a reference to the file where I have the session variables before I try use them?

You can also set session_start() on top inside your admin.inc file, then it would always be there but just written once.

When that is said, i would also recomend to rename the extention in admin.inc from .inc to .php since admin.inc probably contains config settings ? ? Just a safety issue (just ?!)
