Add Language and Translations to the REST API (WPML)
Adds wpml_language and wpml_translations fields to posts and pages in the REST API, so headless front ends and apps know each item's language and the IDs of its translations.
Snippet Library
Snippets for multilingual sites: language switchers, translated strings and per-language behavior with WPML, Polylang and similar plugins. For sites that serve readers in more than one language.
Adds wpml_language and wpml_translations fields to posts and pages in the REST API, so headless front ends and apps know each item's language and the IDs of its translations.
Tells Polylang to copy (and keep in sync) extra custom fields when you create or update a translation, and to stop copying fields that should differ per language.
Copies the custom fields you list from an original post to all of its WPML translations whenever the original is saved, for values like prices, SKUs or coordinates that never change between languages.
Adds pll_language and pll_translations fields to posts and pages in the REST API, which Polylang's free version does not provide, so headless sites and apps can link translations.
Adds a [wpide_wpml_field] shortcode that displays a custom field from the current-language version of any post or page, so one shortcode works in every language.
