Check out this article: http://www.howtodothings.com/compute...r-your-website

It should explain everything you need to know. I tried to answer this question myself, but it is way too general. When asking a question, it should be pretty specific. Some examples would be to ask where to learn how to make a login system, or why you are having problems making yours with the problematic code in your post. It just makes it easier to answer

if you are using php you can do.

<?php
if(!isset)
{ 
echo "welcome, Guest";
//show the login form
 }
else
{
 echo "welcome, $username";
 }
?>

There is more to this of coarse but it is an outline.

 }

The isset function checks whether a variable is set. GET and POST variables are automatically filled out when you submit a form. I think you meant to check whether the user submitted a form by checking whether a certain form variable has been set (corrected above). However, if you want the user name to be remembered on page refresh, you would have to store it is a session (or some other data keeper).

session_start();

if (!isset($_GET['user']) && !isset($_SESSION['user'])) {
  echo 'Welcome, guest.';
  //Display form
} else if (isset($_GET['user']) && !isset($_SESSION['user'])) {
  $_SESSION['user'] = $_GET['user'];
  echo 'Welcome, ' . $_SESSION['user'];
} else {
  echo 'Welcome, ' . $_SESSION['user'];
}

The next step would be to use a database to verify the user name is registered with your site.

I would recommend completing at least the w3schools tutorial in PHP before continuing. You cannot effectively understand a script if you are not versed in PHP's basics.
