• Here’s a custom function to display the page rating by itself anywhere on the page:

    function custom_wpcr3_reviews_info_shortcode($atts) {
        // Shortcode attributes
        $atts = shortcode_atts(
            array(
                'post_id' => null, // Default to null, so it can be used for the current post/page
            ),
            $atts,
            'custom_wpcr3_reviews_info'
        );
    
        // Query to retrieve posts of type 'wpcr3_review'
        $reviews_query = new WP_Query(array(
            'post_type' => 'wpcr3_review',
            'posts_per_page' => -1,
            'meta_query' => array(
                array(
                    'key' => 'wpcr3_review_post',
                    'value' => $atts['post_id'],
                ),
            ),
        ));
    
        // Initialize variables
        $total_reviews = $average_rating = 0;
    
        // Loop through each review post
        while ($reviews_query->have_posts()) {
            $reviews_query->the_post();
    
            // Get post ID and corresponding review post ID
            $review_post_id = get_the_ID();
    
            // Get the rating for the current review post
            $rating = get_post_meta($review_post_id, 'wpcr3_review_rating', true);
    
            // Increment total reviews and add rating to the total
            $total_reviews++;
            $average_rating += intval($rating);
        }
    
        // Reset the post data
        wp_reset_postdata();
    
        // Calculate average rating in stars
        $average_rating = $total_reviews > 0 ? round($average_rating / $total_reviews) : 0;
    
        // Output HTML for displaying reviews info
        $output = '<div class="custom-wpcr3-reviews-info">';
        $output .= '<p><a href="#reviews"><strong>Average Rating:</strong><span style="color:#ff6900;text-shadow: 1px 1px #999;"> ' . str_repeat('★', $average_rating) . ' (' . $total_reviews . ' reviews)</span></a></p>';
        $output .= '</div>';
    
        return $output;
    }
    
    // Register the custom shortcode
    add_shortcode('custom_wpcr3_reviews_info', 'custom_wpcr3_reviews_info_shortcode');
    

    use the shortcode like this: [custom_wpcr3_reviews_info post_id=37]
