1) 📌 1. Issue Overview
When using Views in a multilingual Drupal site, you'll commonly encounter:
- Duplicate content entries across language versions
- English content appearing multiple times on English pages
- SEO warnings for duplicate pages
2) 📌 2. Root Cause
Drupal treats each language version of content as a separate translation. By default, Views displays all versions unless specifically filtered.
3) 📌 3. Solutions to Prevent Duplicates
3.1) ✅ Step 1: Add a Language Filter
- In your View settings, add: Content: Language
- Set filter to: Current user's language
- Save the View
✅ This ensures only content in the active language appears.
3.2) ✅ Step 2: Enable DISTINCT in Query Settings
- Click "Advanced" → "Query settings"
- Enable "Use DISTINCT"
✅ Prevents duplicates when Views join multiple tables.
3.3) ✅ Step 3 (Optional): Use Contextual Filters with Language URL Prefix
- Configure a contextual filter for
langcode - Allows dynamic loading via URLs like
/en/newsor/zh/blog
4) 📌 4. Troubleshooting Tips
| Symptom | Solution |
|---|---|
| Filter doesn't work | Confirm it's set to "Current language", not "Default language" |
| Content disappears after enabling DISTINCT | Check for unnecessary joins |
| Caching causes wrong language | Use per-language URL paths or cache separation |
5) 5. Conclusion
To display clean, language-specific content lists:
- ✅ Always apply a language filter
- ✅ Enable DISTINCT to avoid View-level duplication
- ✅ Contextual filters add flexibility via URL controls
These settings have been tested on Drupal 10 and are recommended for multilingual blogs, news feeds, and content overviews.
