Hello,

Since I'm starting with PHP, I just can't figure out why this sequence does not work. It brings me a clean page with nothing in it.
I ran the script with echo on the "POST[uid']" and "POST['edupdel']" and both are received from the calling script.
All scripts
PHP Code:
<?php
ob_start();
session_start();
if (isset($_POST['uid']))
    { 
        $uid = $_POST['uid'];
    }
else
    {
        die("UID NOT FOUND");
    }
    
if    (!isset($_POST['edupdel']))
    {
        die("Edupdel not found");
    }
else
    {
        $opt =    $_POST['edupdel'];
    }
    
if    ($opt == "listone")
    {
        header('Location:selectone_user.php?uid=$uid');
        exit;
    }

if    ($opt == "noselect")
    {
        header("Location:invalid_option.php");
        exit;
    }

if    ($opt == "update")
    {
        header("Location:update_user.php");
        exit;
    }
if    ($opt == "listall")
    {
        header("Location:listall_user.php");
        exit;
    }
    
if    ($opt == "delete")
    {
        header("Location:delete_user.php");
        exit;
    }
    
if    ($opt == "add")
    {
        header("Location:add_user.php");
        exit;
    }    
ob_end_flush(); 
?>
What is wrong with this code??? (or witth me )


Thank You
