How I can add new css classes to a (specific) post? It already exists or I should make a request for a new hook (if possible)?

Bump! Anyone knows?

Thanks in advance.

You can use the following three filters:

bbp_get_forum_class
bbp_get_topic_class
bbp_get_reply_class

Each of them function exactly like the core WordPress post_class filter: https://codex.wordpress.org/Function_Reference/post_class

How do we implement this? I tried replacing

<ul id="bbp-topic-<?php bbp_topic_id(); ?>" <?php bbp_topic_class(); ?>>

with

<ul id="bbp-topic-<?php bbp_topic_id(); ?>" <?php echo bbp_get_topic_class('test-class'); ?>>

but the test class doesn’t show. I know I’m working with the right line of code because I can remove the class part altogether and see it removed from my site.

I figured this out. I had to add this in my bbpress_functions:

function my_topic_class($classes) {
	$classes[] = 'test-class';
	return $classes;
}
add_filter( 'bbp_get_topic_class','my_topic_class' );
