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!

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');



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

<!doctype html>
<html lang="sv">
    <meta charset="UTF-8">


        if(!count($bibliotek)) {
            echo 'Inga filmer i databasen';
        } else {
        <table border="1">
            foreach($bibliotek as $b) {
                    <td><?php echo esc($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>

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

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

            <p><input type="radio" id="deckare" name="category_id">
            <label for="deckare">Deckare</label></p>

            <p><input type="radio" id="drama" name="category_id">
            <label for="drama">Drama</label></p>

            <p><input type="radio" id="fantasy" name="category_id">
            <label for="fantasy">Fantasy</label></p>

            <p><label for="title">Titel: </label>
            <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">


<?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.
