Exemples de code avancés

Ces exemples démontrent des modèles d'intégration avancés avec Ultimate Multisite.

Moteur de tarification dynamique

Un moteur de tarification basé sur des règles qui applique des remises sur le volume, la fidélité et la saisonnalité :

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;
    }

    private function get_pricing_rules() {
        return [
            [
                'type' => 'volume_discount',
                'condition' => ['total_greater_than' => 100],
                'discount' => 0.1
            ],
            [
                'type' => 'loyalty_discount',
                'condition' => ['customer_tenure_months' => 12],
                'discount' => 0.15
            ],
            [
                'type' => 'seasonal_promo',
                'condition' => ['date_range' => ['2024-11-01', '2024-12-31']],
                'discount' => 0.2
            ]
        ];
    }

    private function rule_applies($rule, $cart, $customer) {
        foreach ($rule['condition'] as $condition => $value) {
            switch ($condition) {

                    if ($cart->get_total() <= $value) return false;
                    break;
                case 'customer_tenure_months':
                    if (!$customer || $customer->get_months_active() < $value) return false;
                    break;
                case 'date_range':
                    $now = current_time('Y-m-d');
                    if ($now < $value[0] || $now > $value[1]) return false;
                    break;
            }
        }
        return true;
    }

    private function apply_rule($rule, $total, $cart) {
        $discount_amount = $total * $rule['discount'];

        wu_log_add('pricing', sprintf(
            'Applied %s rule: %.2f discount on total %.2f',
            $rule['type'],
            $discount_amount,
            $total
        ));

        return $total - $discount_amount;
    }
}

new Dynamic_Pricing_Engine();

Provisionnement avancé de sites

Configurer automatiquement les nouveaux sites avec des plugins, SSL, CDN, sauvegardes et surveillance en fonction des fonctionnalités du plan :

class Advanced_Site_Provisioner {

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

    public function provision_site($site, $membership) {

        // Install plugins based on plan
        $this->install_plan_plugins($plan);

        if ($plan->has_feature('backups')) {
            $this->setup_automated_backups($site, $plan->get_backup_frequency());
        }

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

        restore_current_blog();

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

    private function install_plan_plugins($plan) {
        $plugins = $plan->get_included_plugins();

        foreach ($plugins as $plugin_slug) {
            if ($this->plugin_exists($plugin_slug)) {
                activate_plugin($plugin_slug);
                $this->configure_plugin($plugin_slug, $plan);
            }
        }
    }

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

        if ($result->success) {
            $site->add_meta('ssl_certificate_id', $result->certificate_id);
            $site->add_meta('ssl_status', 'active');
        }

        ]);

        if ($zone->success) {
            $site->add_meta('cdn_zone_id', $zone->id);
            $this->update_cdn_dns($site, $zone);
        }
    }

    private function setup_automated_backups($site, $frequency) {
        $backup_service = new Backup_Provider_API();

        ]);

        $monitoring_service = new Monitoring_API();

        $monitor = $monitoring_service->create_monitor([
            'url' => $site->get_domain(),
            'customer_email' => $customer->get_email(),
            'check_interval' => 300
        ]);

        $site->add_meta('monitoring_id', $monitor->id);
    }
}

new Advanced_Site_Provisioner();

Système de limitations personnalisé

Suivre et appliquer les limites de ressources avec des avertissements d'utilisation :

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);

        switch_to_blog($site_id);

            ));
            return false;
        }

        if ($current_usage >= ($max_storage * 0.8)) {

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