原文外掛簡介
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 selected post types (including custom ones) and taxonomies to identify duplicate titles. Case-insensitive comparison catches duplicates regardless of capitalisation.
Post Type Selection: Choose which post types are included in duplicate title checking from the settings page.
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 Protection: Automatically saves posts with duplicate titles as drafts to prevent accidental publishing, with a dismissible admin notice.
Forbidden Words Filter: Define a list of words or phrases that must not appear in post titles. Choose to block publishing entirely or show a warning while allowing publishing.
Admin Email Notifications: Configure one or more admin email addresses to receive an alert whenever a post with a duplicate title is published. Includes 5-minute throttling to prevent spam.
Duplicate Title Report: A dedicated report page lists all published posts with duplicate titles, grouped by title, with direct edit links.
Real-time Similar Titles: As you type a title, a live list of similar existing titles appears below the input field in both editors.
Dashboard Widget: A dedicated widget on the WordPress dashboard identifies similar or potentially duplicate titles using cosine similarity, with colour-coded scores and direct edit links.
Redesigned Settings Page: A clean, card-based settings UI with toggle switches, inline field descriptions, and a test email button.
Result Caching: Dashboard widget results are cached for one hour to avoid performance issues on large sites.
Mobile Optimised: All admin pages and widgets are fully responsive at the 782px WordPress mobile breakpoint.
Localization Support: Fully translated into 6 languages – English, Persian, Spanish, Portuguese (Brazil), German, and Arabic – with support for adding more.
New in Version 1.9
Security Fix (XSS): The Gutenberg meta box no longer injects post titles into innerHTML. Results are built with DOM APIs and textContent, so malicious titles saved by other users can never execute scripts.
Server-Side Enforcement: Duplicate title and forbidden word checks now also run on REST saves (Gutenberg, mobile apps, other REST clients) instead of relying only on the client-side editor lock. Blocked posts are downgraded to drafts server-side, so publishing cannot be bypassed with direct REST requests.
REST Honours “Allow Duplicate Titles”: The check-duplicate endpoint now returns a blocking message when duplicates are not allowed, and a warning-only message when they are.
Quick Edit Visibility: Saves blocked via Quick Edit / Bulk Edit now show an explanatory error notice on the post list screen instead of failing silently.
Taxonomy Checks Respect Settings: Taxonomy duplicate checks are limited to taxonomies attached to the selected post types.
Accurate Similar Titles: The similar-titles list in the editor excludes the post being edited, accepts post_id, and is capped at 50 results.
Refactor: Duplicate_Title_Validate_Word_Filter methods are static, eliminating duplicate hook registration on every post screen load.
New in Version 1.8
Forbidden Words Filter: Block publishing or show a warning when a post title contains configured words or phrases. Integrated into both Gutenberg and the Classic Editor.
Admin Email Notifications: Notify one or more admins when a duplicate title is published. Configurable email list with a Send Test Email button. 5-minute throttling prevents notification spam.
Post Type Selection: Choose which post types are checked for duplicate titles. Leave all unchecked to check all public post types.
Duplicate Title Report Page: A new submenu page lists all published posts with duplicate titles, grouped by title, with post type badges and direct edit links.
Case-insensitive Comparison: Duplicate detection now uses LOWER() in SQL so “Hello” and “hello” are treated as the same title.
Mobile Optimisation: Settings page, report page, and dashboard widget are now fully responsive.
Bug Fixes: Fixed WooCommerce notice disappearing too quickly, fixed similar titles box hiding on exact duplicate match, fixed pair_key duplication bug in dashboard widget, fixed textdomain loading timing.
All Language Files Updated: All 5 translations (fa_IR, ar, de_DE, es_ES, pt_BR) updated with all new strings.
