Question

$query=sprintf("SELECT member FROM".$table_name."WHERE member=%s AND memberpwd=%s",$membername,$memberpassword);
$result=mysql_query($query);
if(!$result)
{
     echo "Unable to select members";
     mysql_close();
     exit();
}
$rowNum=mysql_num_rows($result);
if(0!=$rowNum)
{
    session_start();
    $user=mysql_result($result,0,'member');
    $_SESSION['user']=$user;
    header('Location:index.php');
    echo "Welcome ".$user;
        exit();
}

I use that code to validate a login user and start his session but nothing is shown in the browser. I would also like the login user to appear in every page he visits, like a forums login member but I don’t know how to use session with cookie to be stored somewhere so that he’ll be remembered in each of his re-visits. This is the hardest part for me to do, could someone please help me ?

EDIT: Sorry, my knowledge of PHP just reaches and stops there-Session part. If I can have an ABC Session explained tutorial, that’ll be really helpful, thank you.

Answer 1

The second special case is the “Location:” header. Not only does it send this header back to the browser, but it also returns a REDIRECT
(302) status code to the browser unless the 201 or a 3xx status code
has already been set. (header() on php.net)

<?php
header("Location: http://www.example.com/"); /* Redirect browser */
/* Make sure that code below does not get executed when we redirect. */
exit;
?>

It is not displayed because of redirect. Place echo "Welcome ".$_SESSION['user']; in index.php.
