I am struggling to implement a plugin / functionality to catch the likes and replies from a source user (giving the like/reply) and notify the destination user (the author of the post) in bbpress, the forum plugin from wordpress.

Are you aware of existing projects implementing this functionality in bbpress (even partially) ?

Which mechanisms / plugins are better to use to trigger actions in the frontend in this case? On the other hand, is it a better approach to put triggers on the database column?

I am more analyzing the database…it has good information, such as user id of the source user, post id. I am talking about the wp_posts table. However, the parent_post is the first post of the topic, so it is not the ierarhical parent post. I need somehow to identify the nested replies from the database, but I dont find the needed information there…

Thank you for your suggestions !

I think I can set triggers on the wp_posts table. The problem is the concept of parent_post.

If you have the structure of posts:

A
B – C
– D
E

In wp_posts, A is considered the parent_post and B,C,D and E are considered replies.

However, in bbpress, I am following a different concept forum-like, where B is considered the parent of C and D.

This piece of info is not in the DB. How can I add a column in wp_posts where I keep the “real” parent of each post?

@zcoin,
bbPress is not different from WordPress. Basic information on the post (a forum, a topic or a reply are all a ‘post) is a record inside the wp_posts table. Then in the wp_postmeta table you will find more information for every post.

Hi Pascal,

Yes, I see that, the problem is that I don’t want to query wp_postmeta just for the “real parent” post (meaning not the parent from wp_posts aka the first post of the topic, but the post being one level up). I am surprised bbPress does not have a separate table. I wanted to avoid performance problems while quering a large table such as the meta table.

Thanks,
Z

there is a hook in the new reply handler you can link to

do_action( ‘bbp_new_reply’, $reply_id, $topic_id, $forum_id, $anonymous_data, $reply_author, false, $reply_to );

you could just create your own table and post the data there.

Thank you for the response, I grepped the whole project and I cannot find the hook you mentioned in your previous post.

But I found in …./bbpress/includes/replies/functions.php the handlers for _bbp_reply_to. I should identify the place where wp_postmeta is populated so I can update my own table as you suggested. If I save the _bbp_reply_to information, I can avoid querying the huge meta table.

PS: I identified a corner case (hope not a bug). _bbp_reply_to gives the “real” parent of the post, but not in the case of the topic post (the first one from the topic).

the hook is in

includes/replies/functions.php line 424

Thank you for the response. I used it to populate my own table.

On the other hand, there is a second option, maybe more optimized: from phpmyadmin, I created a trigger to populate my table when the information I am interested comes in.

As a conclusion, I couldnt find any free plugin for reply / likes notifications to the user. I had to create one.

would you be happy to share it to help others ?

[zcoin]

Yes, I would like to , I am checking how to port my code to a standalone plugin

The whole logic is on how to get the notifications from your own table synch with the posts table:

global $wpdb;
		$results = $wpdb->get_results( "SELECT notif.*, p2.post_title, p2.post_name
								FROM YOUR_NOTIF_TABLE notif 
		            INNER JOIN wp_posts p on p.id = (CASE WHEN notif.parent_id > 0 THEN notif.parent_id ELSE notif.topic_id END) 
								INNER JOIN wp_posts p2 on notif.topic_id = p2.id     
								WHERE p.post_author = $current_user->ID
								AND notif.user_source != $current_user->ID
								AND notif.unread = 1");
								
		$reply_notifications = array();
