    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">

You have 2 problem:

You send submitted form to review.php, so you should read form data in review.php
You did not set form method. As default method is GET, but you read $_POST variable. (What is the default form HTTP method?)

So you should change index.php as follow:

<?php 
    session_start();
    $connect = mysqli_connect('localhost','root','root','review');
    if(isset($_POST['submit']))
    {
        $id = $_POST['id'];
        $_SESSION['name']  = $id;
    }
?>

<!DOCTYPE html>
<html>
<head>
    <title>
        login
    </title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">
</head>
<body>
    <form method="post">
        <input type="text" name="id" placeholder="id">
        <input type="password" name="password" placeholder="password">
    <input type="submit" name="submit" class="btn btn-success">
</form>
</body>
</html>
