自定义模型示例

<?php

namespace My_Addon\Models;

/**
 * Custom Lead model
 */
class Lead extends \WP_Ultimo\Models\Base_Model {

    /**
     * Model name
     */
    protected $model = 'lead';

    /**
     * Set the database table
     */
    protected function set_table() {
        global $wpdb;
        $this->table_name = "{$wpdb->prefix}my_addon_leads";
    }

    /**
     * Get the company name
     */
    public function get_company() {
        return $this->get_meta('company');
    }

    /**
     * Set the company name
     */
    public function set_company($company) {
        return $this->add_meta('company', $company);
    }

    /**
     * Convert lead to customer
     */
    public function convert_to_customer($user_data = []) {
        // Create WordPress user
        $user_id = wp_create_user(
            $user_data['username'] ?? $this->get_email(),
            $user_data['password'] ?? wp_generate_password(),
            $this->get_email()
        );

        if (is_wp_error($user_id)) {
            return $user_id;
        }

        // Create Ultimate Multisite customer
        $customer = wu_create_customer([
            'user_id' => $user_id,
            'email_verification' => 'verified',
            'type' => 'customer'
        ]);

        if (is_wp_error($customer)) {
            return $customer;
        }

        // Copy lead data to customer
        $customer->add_meta('company', $this->get_company());
        $customer->add_meta('lead_source', $this->get_source());

        // Mark lead as converted
        $this->set_status('converted');
        $this->add_meta('converted_customer_id', $customer->get_id());
        $this->save();

        return $customer;
    }
}

管理页面集成

<?php

namespace My_Addon\Admin_Pages;

/**
 * Custom admin page
 */
class Leads_Admin_Page extends \WP_Ultimo\Admin_Pages\Base_Admin_Page {

    /**
     * Page ID
     */
    protected $id = 'my-addon-leads';

    /**
     * Menu position
     */
    protected $position = 30;

    /**
     * Initialize page
     */
    public function init() {
        // Register with Ultimate Multisite
        add_action('wu_register_admin_pages', [$this, 'register']);
    }

    /**
     * Register the admin page
     */
    public function register() {
        wu_register_admin_page($this->id, [
            'title' => __('Leads', 'my-addon'),
            'menu_title' => __('Leads', 'my-addon'),
            'capability' => 'wu_read_leads',
            'position' => $this->position,
            'parent' => 'ultimate-multisite',
            'callback' => [$this, 'render']
        ]);
    }

    /**
     * Render the page
     */
    public function render() {
        // Get leads data
        $leads = My_Addon\Models\Lead::query([
            'number' => 20,
            'paged' => absint($_GET['paged'] ?? 1)
        ]);

        // Render template
        wu_get_template('admin/leads-list', [
            'leads' => $leads,
            'page_title' => __('Manage Leads', 'my-addon')
        ]);
    }
}

测试你的 Addon

<?php

class Test_My_Integration extends WP_UnitTestCase {

    public function setUp() {
        parent::setUp();

        // Create test customer
        $this->customer = wu_create_customer([
            'user_id' => $this->factory->user->create(),
            'type' => 'customer'
        ]);

        // Create test membership
        $this->membership = wu_create_membership([
            'customer_id' => $this->customer->get_id(),
            'plan_id' => $this->create_test_plan()
        ]);
    }

    public function test_custom_field_saves_correctly() {
        $checkout = new WP_Ultimo\Checkout\Checkout();

        // Simulate form submission
        $_POST['company_size'] = 'medium';

        $result = $checkout->process_step_data([
            'company_size' => 'medium'
        ]);

        $this->assertTrue($result);

        // Verify data was saved
        $saved_value = $this->customer->get_meta('company_size');
        $this->assertEquals('medium', $saved_value);
    }

    private function create_test_plan() {
        return wu_create_product([
            'name' => 'Test Plan',
            'type' => 'plan',
            'price' => 50,
            'duration' => 1,
            'duration_unit' => 'month'
        ])->get_id();
    }
}

v2.13.0 扩展点

Ultimate Multisite v2.13.0 添加了多个扩展点，可用于与主权租户、结账域名或主机提供商 DNS 自动化集成的 Addon。

SSO 和主站点管理 URL

Use wu_with_sso($url) when linking customers across domains, especially when a sovereign tenant launches a main-site account, checkout, billing, invoice, template-switching, site-management, or domain-mapping action. The generated URL can be adjusted with wu_sso_url:

add_filter('wu_sso_url', function($sso_url, $user, $site_id, $redirect_to) {
    return add_query_arg('source', 'my-addon', $sso_url);
}, 10, 4);

结账表单基础域名

当你的 Addon 提供额外的共享基础域名，并且这些域名应像结账表单 Site URL 域名一样运行，而不是作为每个站点的自定义映射时，请使用 wu_checkout_form_base_domains：

add_filter('wu_checkout_form_base_domains', function($domains) {
    $domains[] = 'sites.example.com';

    return $domains;
});

Ultimate Multisite 会规范化这些主机，并跳过为它们自动创建的每站点映射域名记录。

自动创建域名记录

当你的 Addon 需要阻止或延迟为新创建的站点自动创建域名记录时，请使用 wu_should_create_domain_record_for_site：

add_filter('wu_should_create_domain_record_for_site', function($create, $site) {
    $domain = (string) $site->domain;

    if ('.internal.example' === substr($domain, -strlen('.internal.example'))) {
        return false;
    }

    return $create;
}, 10, 2);

监听 wu_add_subdomain 的主机提供商集成可以在创建站点时创建提供商端 DNS 记录。如果没有为该操作注册任何集成，Ultimate Multisite 会跳过空的后台任务。
