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
Multilingual snippets for WordPress
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.
Dashboard Widget: Polylang Translation Progress
Adds a dashboard widget showing how many published posts and pages exist in each Polylang language, with a progress bar compared with the default language.
Dashboard Widget: Posts Missing WPML Translations
Adds a dashboard widget that lists your 20 most recent posts and pages in the default language with the languages they still need translating into.
Edit Translations From the Admin Bar (WPML)
Adds a "Translations" menu to the toolbar on single posts and pages with a link to edit each language version, so editors can hop between translations without searching.
Manual hreflang Links for Translated Pages
Adds a box to the editor where you list the URLs of a page's translations; the matching hreflang tags (plus x-default) are printed in the page head, for multilingual sites that do not use a translation plugin.
Polylang Language Fields in the REST API
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.
Polylang Translations Menu in the Toolbar
Adds a "Translations" toolbar menu on posts and pages with links to edit each existing language version, plus links to create the missing ones.
Remove WPML hreflang Tags From Paginated and Filtered Pages
Stops WPML from printing hreflang tags on page 2+ of archives, search results and URLs with query strings, where the alternates often point at mismatched pages.
Set a Different Language for Individual Pages
Adds a "Page language" box to the editor so a single post or page written in another language gets the correct lang attribute (and text direction) for screen readers, spell checkers and search engines.
