bbpress Automate the Insertion of Focus Keyword

Hello,

Thank you for contacting Rank Math.

You can use the code for the topics and replies, you only need to set the post_type to topic and reply in the code.

/**
 * Function to automatically update the focus keyword with the post title, if no focus keyword is set
 */
function update_focus_keywords() {
    $posts = get_posts(array(
    'posts_per_page'	=> -1,
    'post_type'		=> 'reply' // Replace post with the name of your post type
    ));
    foreach($posts as $p){
        // Checks if Rank Math keyword already exists and only updates if it doesn't have it
        $rank_math_keyword = get_post_meta( $p->ID, 'rank_math_focus_keyword', true );
	if ( ! $rank_math_keyword ){ 
            update_post_meta($p->ID,'rank_math_focus_keyword',strtolower(get_the_title($p->ID)));
        }
    }
}
add_action( 'init', 'update_focus_keywords' );

Hello,

Yes, you can use both post types.

You can add multiple post types like this:
'post_type' => ['reply','topic']

Hope that helps.

Thank you.
