Не загружается изображение в базу данных и в указанный путь

У меня сайт в котором есть блок новостей и каталог товаров. Так же есть админ панель, через который должен загружать информация. И не понимаю, где именно пробел что фотография не идет в серверную часть.

А здесь у меня серверная часть кода

    $news_text_eng = $_POST['news_text-eng'];

    $target_dir = "images/";
    $target_file = $target_dir . basename($_FILES["news_thumbnail"]["name"]);
    $uploadOk = 1;

    // Debug output

    if (!in_array($_FILES["news_thumbnail"]["type"], $allowed_mime_types)) {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
        $uploadOk = 0;
    }

    if ($uploadOk) {
        if (move_uploaded_file($_FILES["news_thumbnail"]["tmp_name"], $target_file)) {
            $stmt = $connection->prepare("INSERT INTO news (news_title_kaz, news_text_kaz, news_title_rus, news_text_rus, news_title_eng, news_text_eng, news_image) VALUES (?, ?, ?, ?, ?, ?, ?)");

            if ($stmt->execute()) {

    $connection->close();
    }
}
