[RESOLVED] problems with $_SESSION

[jerrylouise]

<?php
session_start();  

if(isset($_SESSION['search']))
    $_SESSION['search'] = $_SESSION['search'];
else
    $_SESSION['search'] = $_POST['search_box'];
$search_result = $_SESSION['search'];
?>

how do i get the session to change if it reads a different value from the $_POST['search_box'].

You might do something like this:

<?php
session_start();

if (isset($_POST['search_box'])) {
    $_SESSION['search'] = $_POST['search_box'];
}

if (isset($_SESSION['search'])) {
    $search_result = $_SESSION['search'];
    // ...
}

?>

<?php
session_start();  

if(isset($_SESSION['search']))
    $_SESSION['search'] = $_SESSION['search'];
else
    $_SESSION['search'] = $_POST['search_box'];
if(($_GET['search']) == "")
    unset($_SESSION['search']);
$search_result = $_SESSION['search'];
?>

this is what i went with to fix it up

Your fix is not correct. For example, it assumes that $POST['search_box'] exists, but that is not guaranteed. If $SESSION['search'] is set, there is self-assignment, which is silly. It also assumes $_GET['search'] exists, but that is also not guaranteed.
