Doesn’t clear cache when a new comment is posted?

Hi @khromov,

Yes, that’s correct. Inserting a comment doesn’t purge the cache by default. The comment status needs to change for trigger cache invalidation works. (eg: approving)

However, Powered Cache sets a cookie for commented post powered_cache_commented_posts[' . $post_id . '] that way, the page will be served without caching for the user who made a comment.

If you still need to purge the cache, you can give it a try this:

add_action( 'wp_insert_comment', function ( $id ) {
	$comment  = get_comment( $id );
	$post_id  = $comment->comment_post_ID;
	$post_url = get_permalink( $post_id );
	\PoweredCache\Utils\delete_page_cache( $post_url );
} );

It might not be a good decision to leave a cache invalidation to external factors, tho.

Mustafa
