Post-Specific Comments Widget (PSCW)

      Geen reacties op Post-Specific Comments Widget (PSCW)


This super lightweight plugin allows you to specify a post/page ID to display the comments for in a widget. This can come in very handy when trying to showcase the comments from a single post or page, such as customer feedback, testimonials, or guestbook. It can also be set to show all comments, with formatting options and optional avatars.

Allows you to list comments in default manner (by Author and Post Title) or by Author and a variable-character excerpt and ellipsis (or other chosen trailing characters). Two new post formats to version 1.1 are (Excerpt) and (Excerpt) – (Author). Version 1.2 added shortcodes so users can create their own formats! Version 1.2.4 adds an Avatar/Gravatar shortcode.

Thanks for downloading; I hope this can help you. If this really helped you, and especially if you can profit from it, please leave feedback or consider sending a dollar or two my way! Paypal link at right.

If you have questions, don’t hesitate to ask.

How do I use the shortcodes?

If you want to customize the way your comment is printed out, you can use the following shortcodes as placeholders for the intended output: [AUTHOR], [TITLE], [EXCERPT], [DATE].

So for example, if you choose the “other” format, you could then enter “Comment by ~[AUTHOR]~ on [DATE]” and the plugin would magically replace the shortcodes with the author name/link, surrounded by tildes/swiggles, and then the date.

How do I use the avatar shortcode?

[AVATAR] will display a 32px avatar.
[AVATAR 80] will display an 80px avatar.
[AVATAR 128] will display an 128px avatar.
[AVATAR48] and [AVATR 80] will not display avatars because they are not typed correctly.

Avatars will need styling depending on your WordPress theme. There are ample CSS tags to get them where you want them. Avatar display depends on your avatar settings in WordPress – Settings – Discussion

How can I remove the .recentcomments a CSS from the header?

Add the following lines to your (child theme) functions.php file:

function pscw_remove_recent_comments_style() {
    global $wp_widget_factory;
    remove_action( 'wp_head', array( $wp_widget_factory-widgets['WP_Widget_Recent_Comments'], 'recent_comments_style' ) );  
    remove_action( 'wp_head', array( $wp_widget_factory-widgets['Post_Specific_Comments_Widget'], 'pscw_recent_comments_style' ) );
add_action( 'widgets_init', 'pswc_remove_recent_comments_style' );


  1. Upload post-specific-comments-widget.php to the /wp-content/plugins/ directory
  2. Activate plugin through the ‘Plugins’ menu in WordPress
  3. Edit settings under AppearanceWidgets (Hint: add the Post-Specific Comments widget to your sidebar).

The ID number can be found by hovering over the post or page title while in the “All Pages” or “All Posts” list view WordPress panels. The number will show itself after “post=” in your browser’s add-on bar (usually at the lower left hand corner of the screen).

You don’t have to limit the comments to one post or page, though. You can show all your posts/pages by typing in the number 0 (zero) instead of a post number.
