// Handle adding a new service
if (isset($_POST['add_service'])) {
    $service_name = $_POST['service_name'];
    $service_cost = $_POST['service_cost'];
    $service_description = $_POST['service_description']; // New variable for description

    // Insert into services table
    $sql = "INSERT INTO services (service_name, service_price, service_description) VALUES (:service_name, :service_price, :service_description)";
    $stmt = $pdo->prepare($sql);
    $stmt->bindParam(':service_name', $service_name);
    $stmt->bindParam(':service_price', $service_cost);
    $stmt->bindParam(':service_description', $service_description); // Bind description
    $stmt->execute();
}

// Handle deleting a service
if (isset($_POST['delete_service'])) {
    $service_id = $_POST['service_id'];

    // Delete from services table
    $sql = "DELETE FROM services WHERE service_id = :service_id";
    $stmt = $pdo->prepare($sql);
    $stmt->bindParam(':service_id', $service_id);
    $stmt->execute();
}

// Retrieve all services for display
$sql_services = "SELECT * FROM services";
$stmt_services = $pdo->query($sql_services);
$services = $stmt_services->fetchAll(PDO::FETCH_ASSOC);
