So like the title says, $_SESSION['login_user'] returns undefined yet the login form still works. I use $_SESSION['login_user'] after login to store the persons username to use for headings ect. Here is the code below.
index.php
<?php
include('login.php'); // Includes Login Script
if (isset($_SESSION['login_user'])) {
header("location: profile.php"); // Redirecting To Profile Page
}
?>

<form action="login.php" method="post">

login.php
<?php
session_start(); // Starting Session
$error = ''; // Variable To Store Error Message
if (isset($_POST['submit'])) {
if (empty($_POST['username']) || empty($_POST['password'])) {
$error = "Username or Password is invalid";
}
else{
// Define $username and $password
$username = $_POST['username'];
$password = $_POST['password'];
// mysqli_connect() function opens a new connection to the MySQL server.
$conn = mysqli_connect("localhost", "root", "", "sports world");
// SQL query to fetch information of registerd users and finds user match.
$query = "SELECT Username, Password from login where Username=? AND Password=? LIMIT 1";
// To protect MySQL injection for Security purpose
$stmt = $conn->prepare($query);
$stmt->bind_param("ss", $username, $password);
$stmt->execute();
$stmt->bind_result($username, $password);
$stmt->store_result();
if($stmt->fetch()) //fetching the contents of the row {
$_SESSION['login_user'] = $username; // Initializing Session
header("location: profile.php"); // Redirecting To Profile Page
}
mysqli_close($conn); // Closing Connection
}
session.php
<?php
// mysqli_connect() function opens a new connection to the MySQL server.
$conn = mysqli_connect("localhost", "root", "", "sports world");
session_start();// Starting Session
// Storing Session
$user_check = $_SESSION['login_user'];
// SQL Query To Fetch Information Of User
$query = "SELECT Username from login where Username = '$user_check'";
$ses_sql = mysqli_query($conn, $query);
$row = mysqli_fetch_assoc($ses_sql);
$login_session = $row['Username'];

include('session.php');
if(!isset($_SESSION['login_user'])){

I've being trying different things for ages but i just can't get it to work. Note: it did work in a previous version and when comparing the versions nothing seems different...
Cheers
