Works as expected – here’s a custom shortcode

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]
