Hey!

Love your plugin. I noticed Rank Math wasn't showing good meta titles and descriptions for forum pages and topics, so I made this fix and hope I did it correctly.

• Topics: Uses topic title as meta title, first post as description.
• Forums: Uses forum name as meta title, forum description as description.

// Meta description and title for wpForo pages including topics
add_filter('rank_math/frontend/description', function($description) {
    if (function_exists('is_wpforo_page') && is_wpforo_page() && function_exists('WPF')) {
        
        // For TOPIC PAGES - get first post content
        if (!empty(WPF()->current_object['topic']['first_postid'])) {
            $postid = WPF()->current_object['topic']['first_postid'];
            $post = WPF()->post->get_post($postid);
            
            if (!empty($post['body'])) {
                $content = wp_strip_all_tags($post['body']);
                $content = strip_shortcodes($content);
                $content = preg_replace('/\s+/', ' ', $content);
                
                // Trim to 158 characters
                if (strlen($content) > 158) {
                    $content = substr($content, 0, 155);
                    $content = substr($content, 0, strrpos($content, ' ')) . '...';
                }
                
                return $content;
            }
        }
        // For FORUM PAGES - use forum description
        elseif (!empty(WPF()->current_object['forum']['description'])) {
            $content = wp_strip_all_tags(WPF()->current_object['forum']['description']);
            $content = preg_replace('/\s+/', ' ', $content);
            
            if (strlen($content) > 158) {
                $content = substr($content, 0, 155);
                $content = substr($content, 0, strrpos($content, ' ')) . '...';
            }
            
            return $content;
        }
    }
    return $description;
});

// Force Open Graph description for topics
add_filter('rank_math/opengraph/description', function($description) {
    if (function_exists('is_wpforo_page') && is_wpforo_page() && function_exists('WPF')) {
        
        // Specifically for TOPIC PAGES
        if (!empty(WPF()->current_object['topic']['first_postid'])) {
            $postid = WPF()->current_object['topic']['first_postid'];
            $post = WPF()->post->get_post($postid);
            
            if (!empty($post['body'])) {
                $content = wp_strip_all_tags($post['body']);
                $content = strip_shortcodes($content);
                $content = preg_replace('/\s+/', ' ', $content);
                
                if (strlen($content) > 158) {
                    $content = substr($content, 0, 155);
                    $content = substr($content, 0, strrpos($content, ' ')) . '...';
                }
                
                return $content;
            }
        }
    }
    return $description;
});
