[Solved] Prevent other custom rating fields from reducing the product rating

Hi @zo-zo-lee

Kindly change the ratings field meta key 'rating' in the wpDiscuz Form to a different value.

Thanks,
  Is there another way to hook that meta key into the woocommerce rating system?

@zo-zo-lee

No hooks needed. Everything can be done from the admin panel.

I've tried all of that.
  The problem is that the rating then do not show in the general woocommerce rating displays, unless the meta key is "rating"
  But if the main rating field meta key is "rating" then it just averages in my new "size_fit" meta key, or any other ratings or sliding scale information I might want to add, into the main rating and doesn't display any averages for those ones at all.
  I'm trying to get the products to work so that they can give a product 5 stars, but select three for size and fit (center, or just right) just for information purposes.  

Or woocommerce just adds its own "rating" key and averages my custom ratings - which is the same problem, it's reduced by the informational keys

I found a solution that seems to work with custom code to force woocommerce to look only at my custom rating_product key

/**
 * Force WooCommerce to use only the main 'rating' meta and ignore 'size_fit'
 */
add_filter('woocommerce_product_get_average_rating', 'custom_woocommerce_average_rating', 20, 2);

function custom_woocommerce_average_rating($average, $product) {
    // Get all comments/ratings for the product
    $args = array(
        'post_id' => $product->get_id(),
        'status' => 'approve',
        'meta_key' => 'rating_product', // Only get comments with your custom rating field
    );
    
    $comments = get_comments($args);
    
    if (!$comments) return $average;
    
    $total = 0;
    $count = 0;
    
    foreach ($comments as $comment) {
        $rating = get_comment_meta($comment->comment_ID, 'rating_product', true);
        if ($rating) {
            $total += (float) $rating;
            $count++;
        }
    }
    
    return ($count > 0) ? ($total / $count) : $average;
}
