Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/stronganchor/switch-language/archive/refs/heads/main.zipUpdates itself. It ships its own updater (Plugin Update Checker), so new versions appear under Dashboard → Updates.
Switch Language is a WordPress plugin that detects the visitor's browser language, switches the site locale when available, and lets admins extract and translate site text with DeepL.
Features
- Automatic locale switching based on browser language.
- Extracts text from pages, posts, products, and menus.
- DeepL translation support with manual overrides.
- Shortcode-safe translation handling.
- Multi-select target languages with tabbed translation UI.
Installation
- Copy this plugin folder to
wp-content/plugins/switch-language. - Activate Switch Language in the WordPress admin.
- Install any desired language packs in Settings > General > Site Language.
- Add a DeepL API key in Switch Language > DeepL API Settings.
Usage
- Open Switch Language > Extracted Texts.
- Click Extract Texts from All Pages to populate the text list.
- Pick a source language and target languages, then click Update Target Languages.
- Use the per-language tab Translate Texts button to translate for a single target.
- Edit any translation inline and click Save/Update.
- Add the shortcode
[sl_language_switcher]to render a manual language switcher.
Notes
- The "Stored Locale" column reflects the site locale at extraction time; it does not control translation source.
- If no translations are added, confirm the DeepL API key and the selected source language.
- Shortcodes are preserved and not translated.
