Esempi di Codice Avanzato

Questi esempi mostrano modelli di integrazione avanzati con Ultimate Multisite.

Motore di Prezzi Dinamici

Un motore di prezzi basato su regole che applica sconti per volume, fedeltà e stagionalità:

class Dynamic_Pricing_Engine {

    public function __construct() {
        add_filter('wu_cart_total', [$this, 'apply_dynamic_pricing'], 20, 2);
    }

    public function apply_dynamic_pricing($total, $cart) {
        $customer = $cart->get_customer();
        $rules = $this->get_pricing_rules();

        foreach ($rules as $rule) {
            if ($this->rule_applies($rule, $cart, $customer)) {
                $total = $this->apply_rule($rule, $total, $cart);
            }
        }

        return $total;
    }

                'discount' => 0.1
            ],
            [

                'condition' => ['customer_tenure_months' => 12],

                'discount' => 0.2
            ]
        ];
    }

        return true;

        ));

        return $total - $discount_amount;
    }
}

new Dynamic_Pricing_Engine();

Provisioning Avanzato del Sito

Configura automaticamente nuovi siti con plugin, SSL, CDN, backup e monitoraggio in base alle funzionalità del piano:

class Advanced_Site_Provisioner {

    public function __construct() {
        add_action('wu_site_published', [$this, 'provision_site'], 10, 2);
    }

    public function provision_site($site, $membership) {

        }

        // Setup monitoring
        $this->setup_site_monitoring($site, $membership->get_customer());

        restore_current_blog();

        $this->send_provisioning_complete_email($site, $membership);
    }

        }
    }

    private function setup_ssl($site) {
        $ssl_service = new SSL_Provider_API();
        $result = $ssl_service->request_certificate($site->get_domain());

        if ($result->success) {

        ]);

new Advanced_Site_Provisioner();

Sistema di Limitazioni Personalizzato

Monitora e applica limiti di risorse con avvisi di utilizzo:

class Advanced_Limitations {

    public function __construct() {
        add_filter('wu_limitation_plugins_allowed', [$this, 'check_plugin_limit'], 10, 3);
        add_filter('wu_limitation_storage_allowed', [$this, 'check_storage_limit'], 10, 3);

            }
        }

        return round($size / 1024 / 1024, 2);
