Update your code
<?php
session_start();
if(isset($_POST['user']) && $_POST('user')!="") {
$_SESSION['user'] = $_POST['user'];
}
if (isset($_SESSION['user'])){

The session_start() function must appear first while trying to use session variables.
<?php
session_start();
if(isset($_POST['user'])) // check whether the user value is set; The error was because you missed to check whether the $_POST['user'] is set
{
$_SESSION['user'] = $_POST['user'];
echo "You are logged in as ".$_SESSION['user'];
}
else
{
echo "Please login ";
}
?>
