将图像上传到数据库时出现未定义的索引错误

Question

使用mysql将图像上传到数据库时出现问题。

当我单击按钮上传图像时，会出现如下错误：

"Undefined index image in C:\xampp\htdocs\fyp\kemaskinipemandu.php" at line 29 and 30.

我尝试了StackOverflow的其他解决方案，但根本没有解决。因此，这是我的html和php代码。

if (isset($_POST['kemaskini'])){
    $email = $_SESSION['driverEmail'];
    $nama = $_POST['nama'];
    $password = $_POST['password'];
    $cpassword = $_POST['cpassword'];
    $kp = $_POST['kp'];
    $tel = $_POST['tel'];
    $alamat = $_POST['alamat'];
    $exdate = date('Y-m-d', strtotime($_POST['lesen'])); 
    $class = $_POST['jenislesen'];

        $image = $_FILES['image']['name'];//imageUpload
        move_uploaded_file($_FILES['image']['tmp_name'], "img/".$_FILES['image']['name']);

        if($password === $cpassword){
            $query = "UPDATE driver SET driverName='$nama', driverPassword='$password', cpassword='$cpassword', driverICNum='$kp', contNum='$tel', 
            address='$alamat', licenseExDate='$exdate', class='$class', image='$image' WHERE driverID='$driverID';";
            $result = mysqli_query($conn, $query) or die(mysqli_error($conn));

        if($result)
          {
            ?>
            <script>
            alert('Kemas Kini Pemandu Berjaya. ');
            window.location.href="kemaskinipemandu.php";
            </script>
            <?php
          }
        }else {
        ?>
            <script>
            alert('Kata laluan tidak sama. ');
            window.location.href="kemaskinipemandu.php";
            </script>
        <?php
        }
}

和有错误的行是：

$image = $_FILES['image']['name'];//imageUpload move_uploaded_file($_FILES['image']['tmp_name'], "img/".$_FILES['image']['name']);

选择要上传的图片：

<form action="kemaskinipemandu.php" method = "POST" enctype="multipart/form-data">
    <center>
        <?php
        $email = $_SESSION['driverEmail'];
            $query=" SELECT * from driver where driverID='$driverID'";
            $result = mysqli_query($conn, $query) or die(mysqli_error($conn));
            $count = mysqli_num_rows($result);
            if (isset($count) and ($count > 0)) {
                    while($row = mysqli_fetch_assoc($result)){
                        $name = $row['driverName'];
                        $password = $row['driverPassword'];
                        $cpassword = $row['cpassword'];
                        $ic = $row['driverICNum'];
                        $contNum = $row['contNum'];
                        $address = $row['address'];
                        $exdate = $row['licenseExDate'];
                        $class = $row['class'];
                        $image = $row['image'];

        ?>
          <div class="col-md-6">

           <?php  } }?>
          <input type="submit" class="btn btn-primary" name="kemaskini" value="Kemas Kini"></br>
    </center>
    </form>

我希望有人能帮助我。谢谢。
