Ejemplos de Código Avanzado

Estos ejemplos demuestran patrones de integración avanzados con Ultimate Multisite.

Motor de Precios Dinámicos

Un motor de precios basado en reglas que aplica descuentos por volumen, lealtad y temporada:

class Dynamic_Pricing_Engine {

    public function __construct() {

Aprovisionamiento Avanzado de Sitios

Configura automáticamente nuevos sitios con plugins, SSL, CDN, copias de seguridad y monitoreo según las características del plan:

Sistema de Limitaciones Personalizado

Rastrear y hacer cumplir los límites de recursos con advertencias de uso:
