Hi,
The following code sometimes produces output indicating that the session
variables have been set, and sometimes is says that they have not been set.
Unfortunately the server is not mine to configure, but if there is a problem
with it, I can get in touch with the right people. Is the script properly
written? Is it a server problem?
<html>
<head>
<title>Test stuff...</title>
</head>
<body>
<?php
session_start(); // enable session level global variables
if (isset($_POST['action']) && $_POST['action'] == 'sub1' )
sub1();
else {
session_unset(); // all variables start fresh here
$_SESSION['test']='HERE I AM!<br>';
echo $_SESSION['test'];
print_r ($_SESSION);
}
function sub1()
{
echo "sub1 routine<br>";
print_r ($_SESSION);
if ( isset($_SESSION['test']) )
echo $_SESSION['test'];
else
echo 'variable not set<br>';
}
