What are the common pitfalls when using drag and drop functionality in PHP for sorting images in a photo album?

One common pitfall when using drag and drop functionality in PHP for sorting images in a photo album is not properly handling the reordering of images in the database after the drag and drop action. To solve this issue, you need to update the order of images in the database based on the new order set by the user through drag and drop. 

// Assuming you have a table named 'images' with columns 'id' and 'order'

// Retrieve the new order of images from the drag and drop action
$newOrder = $_POST['newOrder'];

// Update the order of images in the database
foreach($newOrder as $index => $imageId) {
    $sql = "UPDATE images SET `order` = :order WHERE id = :id";
    $stmt = $pdo->prepare($sql);
    $stmt->execute(['order' => $index, 'id' => $imageId]);
}
