TranslatePress URL, SEO, And Domain Compatibility

TranslatePress rewrites internal URLs for the active language. The Business SEO Pack can translate slugs and extend sitemaps; Different Domain per Language can map each language to another host. Plugin/theme code must use WordPress URL APIs, avoid manual language-prefix logic, and vary caches by language and host.

When to use this skill

Trigger when ANY of the following is true:

• Code calls home_url(), site_url(), get_permalink(), get_term_link(), post_type_link, term_link, rest_url(), admin_url(), or manually builds absolute links.
• Code parses $_SERVER['REQUEST_URI'], performs redirects, registers rewrites, or handles forms on translated pages.
• The task mentions TranslatePress SEO Pack, URL Slug Translation, trp_get_url_for_language, trp_translate_slugs_on_internal_links, trp_hreflang, Different Domain per Language, multilingual sitemap, translated WooCommerce slugs, CORS, canonical, or hreflang.

Generate URLs safely

Prefer WordPress URL functions and let TranslatePress filter them:

$url = get_permalink( $post_id );
