comments for draft posts

The ‘comment_on_draft’ action fires just before the script exits, essentially ignoring the comment POST. You can’t stop the exit, but you should be able to add a comment from the action callback by compiling the data in $_POST and then calling wp_new_comment().

Hello bcworkz,

unfortunately the hook ‘comment_on_draft’ never fires.

The reason is, the function ‘wp_ajax_replyto_comment’ dies with: ‘ERROR: you are replying to a comment on a draft post.’ before the hook fires.

global $wp_list_table;
	if ( empty( $action ) )
		$action = 'replyto-comment';

	check_ajax_referer( $action, '_ajax_nonce-replyto-comment' );

	$comment_post_ID = (int) $_POST['comment_post_ID'];
	$post = get_post( $comment_post_ID );
	if ( ! $post )
		wp_die( -1 );

	if ( !current_user_can( 'edit_post', $comment_post_ID ) )
		wp_die( -1 );

	if ( empty( $post->post_status ) )
		wp_die( 1 );
	elseif ( in_array($post->post_status, array('draft', 'pending', 'trash') ) )
		wp_die( __('ERROR: you are replying to a comment on a draft post.') );

Is there any way to setup a hook before ‘wp_ajax_replyto_comment’ fires for example to override $post->post_status?

Hmmm, it does fire on my installation when adding a comment from the draft preview page. At least when the commenter is logged in, I didn’t test further.

From where are you trying to add a comment? I’m not seeing any other option besides adding from the preview page.

I have add the comment metabox at the functions.php for draft posts.

Now i want to add a comment from wp-admin/post.php?post=postID&action=edit.
I can see the metabox and existing comments but i can’t add new comments.

WordPress dies each time on this position

elseif ( in_array($post->post_status, array('draft', 'pending', 'trash') ) )
		wp_die( __('ERROR: you are replying to a comment on a draft post.') );

I’m afraid there’s no hook to intervene in that situation. What you could do is use javascript to change the ‘action’ hidden field (if that’s where the ‘replyto-comment’ is coming from) to something else. This will cause the AJAX request to be channeled to a callback function of your choosing, where you can save the comment regardless of post status.

The action value could also be part of the AJAX event handler, in which case you’d have to override the event handler itself. Another option would be to insert a completely custom meta box so everything is handled the way you want it.

Or just add comments from the preview page and use the hook I originally suggested.

You are right, it’s a pity that there is no hook.

I’m trying your suggestion and post my solution here.

I have tried to manipulate the hidden fields with javascript but it doesn’t work.
But what works is to regist a new post status for example “draft_comment”.

Mybe it is not the right way but it works for my project.
I hope in the future there is a hook to handle this case.
