Inserting into database not working

Hi guys. I really need help with this, I've been at it for hours and i am honestly about to give up.

I cant get this code to insert information into my database for the life of me! Does anyone know what i'm doing wrong? I'm getting no errors, but nothing's happening either! 

<?php 
require_once 'login.php';
require_once 'security.php';

$bibliotek = array();

if(!empty($_POST)) {
    if(isset($_POST['title'], $_POST['director'], $_POST['year'])) {

        $title = trim($_POST['title']);
        $director = trim($_POST['director']);
        $year = trim($_POST['year']);
        $category_id = trim($_POST['category_id']);

        if(!empty($title) && !empty($director) && !empty($year)) {
            $insert = $db->prepare("INSERT INTO `movies`.`filmer` (`id`, `title`, `director`, `year`, `category_id`) 
            VALUES (NULL, '?', '?', '?', '?')");
            $insert->bind_param('ssi', $title, $director, $year, $category_id);

            if($insert->execute()) {
                header('Location: index.php');
                die();
            }

        }

    }
}

if($results = $db->query("SELECT * FROM filmer")) {
    if($results->num_rows) {
        while($row = $results->fetch_object()) {
            $bibliotek[] = $row;
        }
        $results->free();
    }
}
?>

<!doctype html>
<html lang="sv">
<head>
    <meta charset="UTF-8">
    <title>Bibliotek</title>
</head>
<body>

    <h3>Filmer</h3>

    <?php 
        if(!count($bibliotek)) {
            echo 'Inga filmer i databasen';
        } else {
    ?>
        <table border="1">
            <thead>
                <tr>
                    <th>Titel</th>
                    <th>Regissör</th>
                    <th>År</th>
                    <th>Kategori</th>
                    <th>Uppdatera</th>
                    <th>Radera</th>
                </tr>
            </thead>
            <tbody>
            <?php
            foreach($bibliotek as $b) {
            ?>
                <tr>
                    <td><?php echo esc($b->title); ?></td>
                    <td><?php echo esc($b->director); ?></td>
                    <td><?php echo esc($b->year); ?></td>
                    <td><?php echo esc($b->category_id); ?></td>
                    <td>Uppdatera</td>

                </tr>
            <?php 
            }
            ?>
            </tbody>
        </table>
    <?php 
    }
    ?>

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

            <p><input type="radio" id="action" name="category_id">
            <label for="action">Action</label></p>

            <input type="text" id="title" name="title"></p>

            <p><label for="director">Regissör: </label>
            <input type="text" id="director" name="director"></p>

            <p><label for="year">År: </label>
            <input type="text" id="year" name="year"></p>

            <input type="button" value="Lagra">

    </form>

</body>
</html>

<?php // inloggnings uppgifter (login.php)
    $db = new mysqli('localhost', 'root', '', 'movies');

    if($db->connect_errno) {
        die("Kunde inte ansluta till databasen.");
    }
?>

<?php // Förhindra XSS attacker (security.php) 
    function esc ($string) {
        return htmlentities(trim($string), ENT_QUOTES, 'UTF-8');
    }
?>

If you can help me it would mean the world to me. I've been struggling with this task since Tuesday and i haven't even been able to insert data yet!

There are some things in your code I have not learned yet, but you are missing a ; on the $insert line.
