WP REST API, Comments Not Triggering 'comment_post'

[stickypixel]

Hello,

I’ve noticed that when comments are created using the WP API that notification emails are not sent out to the author of the post or moderators. (When testing, If I add the comment via the admin interface, it works as expected).

On debugging, I noticed that the filter ‘comment_post’ is not being called when inserted via the API. For now, I used the following workaround:

function mytheme_comment_inserted($comment_id, $comment_object) {
  wp_notify_postauthor( $comment_id );
}
add_action('wp_insert_comment','mytheme_comment_inserted');

I already posted on the support forum here: ​https://wordpress.org/support/topic/wp-api-comments-not-sending-notifications/#post-8987973 and it was suggested this could be intentional behaviour but that this also could, in fact, be reported as a bug?

Thanks!

Chris

Thanks for the ticket @stickypixel.

This is caused by the comment controller calling wp_insert_comment() directly, instead of calling wp_new_comment(), which is the function that triggers the comment_post action and is used throughout the rest of the admin area.

This might be an intentional design decision by the REST API team.

Hi All,
I have done a bit of digging into this, and I came across this ​GitHub Issue that revolved around the same issue. Looking at the last comment, it appears that this was an intentional decision, as wp_new_comment() does a lot of unwanted functionality in the instance of the REST API. As of such this functionality is unlikely to change, and I am going to mark this is wontfix. However if you have anything else to add to the discussion please reopen the ticket. 😃
