php unidentified index error message

Since I added


I've been getting this error message.

Undefined index: city in C:\wamp\www\assignment\html\img_upload.php on line 39.

city is a select field in the form.

This is the code

require 'login.php';

$path = 'img/';
if (isset($_POST['submit'])) {
// Grab the image from the POST array
//$gend = $_POST['gender']; not using now
$pic = $_FILES['pic']['name'];
if (!empty($fn) && !empty($ln) && !empty($pic)) {
// Move the file to the target upload folder
$target = $path.$pic;//create image source (src)
if (move_uploaded_file($_FILES['pic']['tmp_name'], $target)) {

// // Connect to the database
$dbase = mysqli_connect('localhost', 'root', '', 'flowers');
// Write the data to the database
$my_query = "insert into members values ('$fn', '$ln', '$sex','$city','$em','$pass', '$pic');";
mysqli_query($dbase, $my_query);

$result = mysqli_query($dbc, $query);

if ($result){
// // Confirm success with the user
// echo '<p>Thank you for registering with us!</p>';
// echo '<p><strong>Name:</strong> ' . $fn .' '.$ln .'<br />';
// echo '<img src="' . $path . $pic . '" alt="profile image" /></p>';
// echo '<p><a href="index.html">&lt;&lt; Return to home page</a></p>';
else echo "Sorry you have an error: ".$mysqli_error($dbc);

It seems that you have not posted the variable $_POST['city'].

Whenever you have dynamic fields in your form, you are unsure which fields will get posted.

In this case, use isset().

$city = isset($_POST['city']) ? $_POST['city'] : '';

This ensures that you do not get any Notice error.
