详情介绍:
Duplicate Title Validator is a robust WordPress plugin designed to ensure the uniqueness of post titles across all post types and taxonomies. By preventing duplicate titles, this plugin enhances both SEO and user experience. Whether you use Gutenberg or the Classic Editor, it seamlessly integrates to maintain title uniqueness.
Key Features
- Comprehensive Duplicate Detection: Scans all post types (including custom ones) and taxonomies to identify duplicate titles.
- Gutenberg Publish Lock: In the block editor, the Publish button is fully disabled when a duplicate title is detected, with a pre-publish warning panel showing the conflicting titles.
- Classic Editor Draft Mode: Automatically saves posts with duplicate titles as drafts to prevent accidental publishing, with a dismissible admin notice.
- Real-time Similar Titles: As you type a title, a live list of similar existing titles appears below the input field.
- Dashboard Widget: A dedicated widget on the WordPress dashboard identifies similar or potentially duplicate titles using cosine similarity, with direct edit links.
- Redesigned Settings Page: A clean, card-based settings UI with toggle switches and inline field descriptions.
- Result Caching: Dashboard widget results are cached for one hour to avoid performance issues on large sites.
- Localization Support: Fully translated into 6 languages — English, Persian, Spanish, Portuguese (Brazil), German, and Arabic — with support for adding more.
- Gutenberg Publish Lock: Publishing is now fully blocked in the block editor when a duplicate title is detected and "Allow Duplicate Titles" is disabled — the Publish button is locked via the official
lockPostSavingAPI. - Pre-publish Warning Panel: A colour-coded panel appears in the Gutenberg pre-publish checklist, listing all conflicting titles and explaining why publishing is blocked.
- Redesigned Settings Page: Replaced the plain WordPress settings form with a modern card-based UI featuring a dark header, toggle switch for the allow-duplicates option, and inline field descriptions.
- Redesigned Dashboard Widget: Complete visual overhaul with colour-coded similarity badges (red / orange / green), grouped cards per title, and a cleaner layout.
- Donation & Support Section: Added a support section to both the settings page and the dashboard widget.
- Bug Fixes: Fixed incorrect
load_plugin_textdomainpath, wrong text domain string in title checker, flawed similar-title filter logic, duplicatewp-pluginsscript dependency, and missing input sanitization in Gutenberg REST API handlers. - Performance: Dashboard widget results are now cached with a one-hour transient; duplicate pair comparisons skip already-seen pairs to reduce O(n²) overhead.

常见问题:
Does this plugin support custom post types and taxonomies?
Yes, it checks for duplicate titles across all registered post types and taxonomies, including custom ones.
What happens in Gutenberg when a duplicate title is detected?
The Publish button is locked and a warning panel appears in the pre-publish checklist listing all conflicting titles. The lock is released as soon as the title is changed to a unique one.
What happens in the Classic Editor?
The post is saved as a draft instead of being published, and an admin notice is displayed explaining the duplication source.
Can I allow duplicate titles if I need to?
Yes. Go to Duplicate Title > Settings and enable "Allow Duplicate Titles." In Gutenberg this shows a dismissible warning instead of blocking publishing.
Can I translate this plugin into other languages?
Absolutely! The plugin is translation-ready. Add translations by creating .po and .mo files in the languages directory.
Does the plugin affect site performance?
The plugin is optimized for performance. Dashboard widget results are cached for one hour. On very large sites, the similarity scan limit can be reduced in the settings.
How do I update the plugin?
Updates can be done directly via the WordPress dashboard. Always back up your site before updating.
