Considerations for running Lang Forge on WordPress Multisite installations.

Per-Site Configuration

In a Multisite setup, each site has its own independent Lang Forge configuration. Languages, translations, and settings are stored per-site in each site’s database tables.

// Each site in a network can have different languages
// Site 1 (example.com): Russian + English
// Site 2 (blog.example.com): Russian + German + French
// Each site is fully independent

Shared Content Across Network Sites

If you need to share translations across network sites, you can build a custom sync mechanism:

/**
 * Sync a translation group across network sites.
 * Call this after creating translations on the source site.
 */
function theme_sync_translations_to_network($post_id, $target_blog_id) {
    $source_post = get_post($post_id);
    $source_lang = lf_get_post_language($post_id);
    $translations = lf_get_post_translations($post_id);

    switch_to_blog($target_blog_id);

    // Create or update the post on the target site
    $target_post_id = wp_insert_post([
        'post_type'    => $source_post->post_type,
        'post_title'   => $source_post->post_title,
        'post_content' => $source_post->post_content,
        'post_status'  => $source_post->post_status,
    ]);

    if ($target_post_id && !is_wp_error($target_post_id)) {
        LF_Post_Translation::instance()->set_post_language($target_post_id, $source_lang);
    }

    restore_current_blog();

    return $target_post_id;
}

Example: Network-wide translation status report

// Generate a translation status report across all sites
function theme_network_translation_report() {
    $sites = get_sites();
    $report = [];

    foreach ($sites as $site) {
        switch_to_blog($site->blog_id);

        $languages = lf_get_languages();
        $site_data = [
            'url'       => get_home_url(),
            'languages' => [],
        ];

        foreach ($languages as $code => $lang) {
            $count = new WP_Query([
                'post_type'  => 'any',
                'meta_key'   => '_lf_language',
                'meta_value' => $code,
                'fields'     => 'ids',
            ]);
            $site_data['languages'][$code] = $count->found_posts;
        }

        $report[$site->blog_id] = $site_data;

        restore_current_blog();
    }

    return $report;
}
