Как изменить строку из БД?

Как-то так надо сделать?

<form class="msg-wall" method="post" action="/vendor/wall.php">
            <p>
                Message Wall:
            </p>
            <input type="text" name="wall" placeholder="What are you thinking about?">
            <button type="submit">Publish</button>

            <?php foreach($check_message as $row) { ?>
                <div class="content">
                    <p class="msg"><?= $row['message'] ?></p>
                    <input type="text" name="edit">
                    <input type="hidden" name="id" value="<?= $row['id'] ?>">
                    <a href="?ed=<?= $row['id'] ?>">edit</a>
                </div>
            <?php } ?>

        </form>

if (isset($_GET['ed'])) {
    $id = $_POST['id'];
    $value = $_POST['edit'];
    mysqli_query($connect, "UPDATE message SET message = '$value' WHERE id = $id");
    header('Location: ../profile.php');
}
