This plugin has been deprecated! It is no longer necessary as its functionality has been integrated into WordPress. There will not be any continued support for it. Comments to this post are also now closed.
When I released the plugin, I also simultaneously made a bug report and patch for the WP core, which was quickly accepted and applied.
Prevent visitors from leaving duplicate comments/pingbacks/trackbacks to a post.
* Requires at least WordPress 1.5.
* A duplicate is a comment/pingback/trackback that meets these criteria:
Its contents match that of another comment in the same post
Either the commenter’s name or e-mail address (if provided) also match.
I won’t claim this approach won’t lead to false-positives, but as far as I’m concerned it’s reasonable.
* If a comment is deemed to be a duplicate, an error page is displayed to the user indicating as much.
- Download the file no-duplicate-comments.zip and unzip it into your /wp-content/plugins/ directory.
Copy and paste the the code ( no-duplicate-comments.phps ) into a file called no-duplicate-comments.php, and put that file into your /wp-content/plugins/ directory. Please ensure you do not introduce any spaces or other characters before the <?php or after the ?>
- Activate the plugin from your WordPress admin ‘Plugins’ page.
function c2c_no_duplicate_comments ( $comment_text )
- $comment_text : The text of the comment to be checked for duplication.
