bbPress.org

Seeing the filters in bbpress.php:

// Post type identifiers

$this->forum_post_type    = apply_filters( 'bbp_forum_post_type', 'forum'     );

$this->topic_post_type    = apply_filters( 'bbp_topic_post_type', 'topic'     );

$this->reply_post_type    = apply_filters( 'bbp_reply_post_type', 'reply'     );

I thought this could be easily modified; however, I am struggling to get my filters to work from functions.php. I’ve tried the following solutions:

add_filter( 'bbp_forum_post_type' , function($post_type) { return 'wps_' . $post_type; } );

add_filter( 'bbp_topic_post_type' , function($post_type) { return 'wps_' . $post_type; } );

add_filter( 'bbp_reply_post_type' , function($post_type) { return 'wps_' . $post_type; } );

And,

add_filter( 'bbp_forum_post_type' , 'wps_my_custom_post_type' , 1, 1 );

add_filter( 'bbp_topic_post_type' , 'wps_my_custom_post_type' , 1, 1 );

add_filter( 'bbp_reply_post_type' , 'wps_my_custom_post_type' , 1, 1 );

function wps_my_custom_post_type( $post_type ) {

//just add prefix

$prefix = 'wps_';

return $prefix . $post_type;

}

Neither seem to work, and I am not sure what I am missing.
