TranslatePlus for Polylang

TranslatePlus for Polylang adds a TranslatePlus-powered translation workflow to WordPress content managed with Polylang.

What this plugin translates

Post editor: “Translate with TranslatePlus”

Creates a new draft in the target language and links it in Polylang. Content sent to TranslatePlus includes:

• Post title and excerpt (plain text)
• Post content as HTML (blocks / typical editor HTML, via the HTML translation API)
• Custom fields / post meta — copied from the source post and translated recursively where values are text or serialized structures; technical keys are excluded (thumbnail, locks, _pll*, many WooCommerce ID/price fields, etc.). Extend exclusions with the tppl_excluded_post_meta_keys filter.
• URL slug — derived from the translated title and made unique
• Featured image — file duplicated in the media library; attachment title, caption, description, and alt text translated

Taxonomies: term IDs from the source post are attached to the draft (structure preserved). Term names are not auto-translated.

Disable the meta/slug/featured-image pass with the tppl_translate_post_extended_enabled filter (return false) if you only want title, excerpt, and content.

Settings: Polylang strings (bulk)

Optionally bulk-translate Polylang string translations for a selected language (many widget strings and other strings Polylang stores). This is not a full site or menu translation tool.

Not covered

Whole navigation menus, arbitrary widgets/options, or SEO fields unless they appear in post HTML or in Polylang’s string storage as above.
