    About to Toss my Cookies

    I am trying to capture and store the value of a sort parameter as one hops
    around various web pages. When they get back to main page, I want the data
    from a database to be sorted the same way as the left it.

    I was thinking to use cookies to retain the sort value, but it is not
    working as I would expect. Another problem is that all the documentation I
    find is either too old or too new for my version (PHP Version 4.3.4).

    Here is what I have tried, but it is not working.


    <?php
    session_start() ;
    if (empty($sort_ke y)) {
    setcookie("sort _key","est_star t");
    }
    ?>

    <HTML>
    <BODY>
    <HEAD>
    <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
    </HEAD>
    <?php

    $sort_key = $_POST['sort'];
    $_SESSION["sort_key"] = $sort_key;
    $sort_key = $_SESSION['sort_key'];



    if (empty($sort_ke y)) {
    $sort_key="est_ start";
    }

      Is register_global s on? If not, how does $sort_key get to be not empty in
      the 3rd line?

      Here's one way to do it:
      <?
      session_start() ;
      if($_REQUEST['sort_key'])
      {
      $_SESSION['sort_key']=$_REQUEST['sort_key'];
      }
      $sort_key = $_SESSION['sort_key'];
      if(empty($sort_ key))
      {
      $sort_key='est_ start';
      }
      /* ... Do your database stuff here (don't forget to validate
      $sort_key!)...*/
      ?>

          If you're using session, don't mess with the cookie. To initialize a session
          variable just do

          $_SESSION['sort_key'] = 'something';

          What you want is a "sticky variable." That is, its value changes when the
          variable is present in the request, but is otherwise preserved. The logic
          should be as so:

          if(isset($_REQU EST['sort_key'])) {
          $_SESSION['sort_key'];
          }
          else if(!isset($_SES SION['sort_key'])) {
          $_SESSION['sort_key'] = 'default';
          }
