I’ve got a problem. I’m sure I’m being really stupid but I can’t seem to be able to rertive a $_SESSION variable.
I run through the code three times using a variable called $setup which I post each time as reset. The first time I go through the code, $setup has no value. The second time, it has the value of 1 and a SESSION variable called value 1 gets set from a POST. The third time, setup has the value of 2. I set a SESSION variable to the value of another POST but the orignal SESSION variable seems to have disappear according to using print_r to find out what SESSIONS are set.
<?php
session_start();
$setup=$_POST['reset'];
if ($setup==NULL)
{
$setup=0;
}
elseif ($setup==1)
{
$_SESSION['value1']=$_POST['value1'];
$value1=$_SESSION['value1'];
}
elseif ($setup==2)
{
$value1=$_SESSION['value1'];
$_SESSION['value2']=$_POST['value2'];
$value2=$_SESSION['value2'];
}
?>
