How to Disable Comments Programmatically in WordPress

Sometimes you may need to programmatically disable the comment form. This can be done using the “comments_open” hook:

add_filter('comments_open', function($open, $post_id)
{
	return false;
}, 10, 2);

This hook accepts two parameters:

$open — whether the current post is open for comments
$post_id — the ID of the current post

It’s a very useful hook that allows you to dynamically enable or disable comment visibility.

In combination with it, you can use the “comment_form_comments_closed” hook, which is triggered when commenting is disabled:

add_action('comment_form_comments_closed', function()
{
	echo '[TEST]';
});
