Как сделать комментарий от авторизованного пользователя?

<?php 
    
    if (isset($_POST['send'])) {
        if (trim($_POST['name']) == "" || trim($_POST['message']) == "" || trim($_POST['email']) == "" ) 
        {
            $err = "Заполните поле";
        } else
        {
    
    $koments = R::dispense('komentss');
    $koments->name = $_POST['name'];
    $koments->email = $_POST['email'];
    $koments->message = $_POST['message'];

    R::store($koments);
    
}

}
 ?>

<?php $komen = mysqli_query($con, "SELECT * FROM `komentss` ORDER BY `id`") ?>
                    <?php while($kom = mysqli_fetch_assoc($komen)) {  ?>
                        <div class="media">
