    Session Variables Lost - Help

    I am having difficulty in setting variables in a session, and then
    accessing those variables throughout the web pages that they click
    on. After having them set a user name and password, successfully
    authenticating against Active Directory, I send them from the
    login.php page to the index.php page. But when I get to the index.php
    page, the session ID is visible, but the session variables and values
    are not. Can you help me out? Also, I'm curious how to distinguish
    between various sessions if multiple ones are available. My files are
    below. Thanks.

    Eddie

    -- excerpt of login.php page

    start_session() ;

    $user= $_POST[u];
    $pass= $_POST[p];

    if (isset($_SESSIO N[user]) and ($_SESSION[user]==$user)){

    $_SESSION[auth] = admin_all;
    $_SESSION[user] = $user;
    $_SESSION[timelast] = time();
    $_SESSION[email] = 'testemail@test domain.com';

    header('Locatio n: http://mydomain.com/index.php');
    }

    but when I go to the on to the index.php page, I cannot see the
    results. What am I missing?


    -- excerpt of index.php page

    $sessname = session_name();
    $sessid = session_id();
    session_start() ;

    print "<pre>\nContent s of \$_COOKIE:\n";
    foreach ($_COOKIE as $k =$v) {
    print " $k = $v\n";
    }

    print "\nContents of \$_SESSION:\n";
    foreach ($_SESSION as $k =$v) {
    print " $k = $v\n";
    }
    print "</pre><br>";

    print "sessionuse r = " . $_SESSION[user] . " <br>";
    print "sessiontimelas t = " . $_SESSION[timelast] . " <br>";

    -- output of index.php page

    Contents of $_COOKIE:
    PHPSESSID = e12d796fc6e3735 69202c58d8f0968 15

    Session name = PHPSESSID
    Session id = e12d796fc6e3735 69202c58d8f0968 15

    session.use_coo kies = 1
    session.name = PHPSESSID
    session.auto_st art = 0
    session.cookie_ lifetime = 0
    session.seriali ze_handler = php

      Hi Eddie,

      First: A client (browser) does NOT have multiple sessions.
      It can have multiple sessions to DIFFERENT DOMAINS, but not within one.

      The session is defined by the value of PHPSESSID, which can be stored in
      a cookie, or via URL-rewritting, or even hidden var in POST.
      As long as PHP received a PHPSESSID, you have a session.

      IF PHP has a corresponding file with that id, you have a session.

      Why don't you use formal notation for associative arrays?
      $_POST["u"];
      $pass= $_POST[p];
      >
      if (isset($_SESSIO N[user]) and ($_SESSION[user]==$user)){
      >
      $_SESSION[auth] = admin_all;
      What is admin_all?
      Didn't you mean:
      $_SESSION["auth"] = "admin_all" ;
      or maybe
      $_SESSION["auth"] = $admin_all;


      $_SESSION[user] = $user;
      $_SESSION[timelast] = time();
      $_SESSION[email] = 'testemail@test domain.com';
      >
      header('Locatio n: http://mydomain.com/index.php');
      You forgot the exit command here.
      Setting a header will NOT stop the script.
      It runs on, and I have no clue what follows. Maybe a reset on the session?
      }

      This can be done much easier with print_r, like this:
      echo "<pre>";
      print_r($_COOKI E);
      echo "<pre>";

      same for $_POST and $_GET and $_SESSION.
      Use print_r() (with pre) to dump ANY (complex) array.

      Also: are you sure you stay in the same domain after the
      header("Locatio n.....");
      ??
      Sessions cannot (easily) span domains, luckily. ;-)

          PS: Make sure you have ALL error/notices reporting on.

          add above your script:
          error_reporting (E_ALL);

              start_session() isn't a php function (unless you declared a function

                  You're right. My code says session_start() . :-)

                      start_session() isn't a php function (unless you declared a function

                      You're right. My code says session_start() . :-)
                      This is most likely not your problem, but I thought I'd mention it
                      because I just had the same thing happen to me today.

                      If you have anything like Zone Alarm installed, make sure it isn't
                      messing with your sessions. Mine was, and as soon as I disabled it,
                      everything worked fine.

                              I would try using session_write_c lose() right before your header()
                              statement - and see if that helps. From time to time, setting new
                              variables in sessions won't stick for whatever reason, unless you
                              close a session on that page first.
