How to Add Shortcode Support to WordPress Comments

Do you want to add shortcode support to WordPress Comments? With our snippet, you can whitelist some shortcodes that you want to enable on WordPress comments.

Instructions:

All you have to do is add these code snippets to your theme’s functions.php file or in a site-specific plugin:

The first snippet removes all shortcodes and reinitializes only those listed within init_common_shortcodes function. The second sample snippet replaces the [mysite] shortcode with the user’s website URL.

Snippet #1

function init_common_shortcodes() {
  // add each shortcode you want enabled in comments
  add_shortcode('mysite', 'mysite');
}
 
function init_comment_shortcodes() {
  remove_all_shortcodes();
  init_common_shortcodes();
  add_filter('comment_text', 'do_shortcode');
}
 
init_common_shortcodes();
add_filter('comments_template', 'init_comment_shortcodes');

Snippet #2

function mysite(){
	return '<a href="' .get_comment_author_url(). '">(My website)</a>';
}
add_shortcode('mysite', 'mysite');
