用于登录的PHP会话 - 无法识别

Question

I'm writing a login code for my control panel for my website. I've made the login script. But for some reason the session doesn't save, here is the parts of my code I use:

index.php

session_start();

if(isset($_POST['username']) && isset($_POST['password'])) {
    require('scripts/validateLogin.php');
}

if($_SESSION['login'] == 1) {
    $loginOkay=1; 
    echo "Logged in";
} else {
    $loginOkay=0;
    echo "Not logged in";
}

validateLogin.php

require('mysql_connect.php');

$username = htmlspecialchars(strtolower($_POST['username']));
$password = md5(htmlspecialchars($_POST['password']));

$result = mysqli_query($con, "SELECT username,password FROM tb_mods WHERE username = '$username';");

while($row = mysqli_fetch_array($result)) {
    if ($row['username'] == $username && $row['password'] == $password) {
        $_SESSION['login'] == 1;
    }
}

I call session_start(); before I load my loginValidation.php so session_start(); is active in both pages.

I keep getting: Not logged in as result.

I think the line $_SESSION['login'] == 1; is wrong, you need only one equal character to add value to the session variable. I hope it will help.
