What are the potential challenges when editing object-to-customer assignments in PHP?

When editing object-to-customer assignments in PHP, one potential challenge is ensuring that the assignments are updated correctly without causing data inconsistencies. To solve this, it is important to validate the input data and handle any errors gracefully to prevent unintended changes to the database. 

// Sample PHP code snippet to update object-to-customer assignments

// Assuming $object_id and $customer_id are the updated values
$object_id = $_POST['object_id'];
$customer_id = $_POST['customer_id'];

// Validate input data
if (!is_numeric($object_id) || !is_numeric($customer_id)) {
    echo "Invalid input data";
    exit;
}

// Update assignments in the database
// Add your database connection code here
$query = "UPDATE assignments SET customer_id = $customer_id WHERE object_id = $object_id";
$result = mysqli_query($conn, $query);

if ($result) {
    echo "Assignments updated successfully";
} else {
    echo "Error updating assignments: " . mysqli_error($conn);
}
