Undefined index error when uploading image into database - php

Question

I have a problem when uploading image into database using mysql.
When I click button for upload the image, the error comes out like this:
"Undefined index image in C:\xampp\htdocs\fyp\kemaskinipemandu.php" at line 29 and 30.
I've tried other solution from StackOverflow but it didn't work out at all. So, here is my html and my php code.
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
}
}
and the line that have error are :
$image = $_FILES['image']['name'];//imageUpload
move_uploaded_file($_FILES['image']['tmp_name'], "img/".$_FILES['image']['name']);
Select image to upload:
<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'];
?>
