Php 在WooCommerce Admin产品列表自定义列中显示来自元数据的统计数据

基于对上一个问题的Count Add To Cart clicks and display them in WooCommerce Admin Product list个答案，我正在try 进一步修改代码，不仅包括点击和销售，还包括将两者分开，以便更好地了解销售情况.

这是我无法让它工作的代码:

function add_to_cart_click_counter( $product_id ) {

    $product = wc_get_product( $product_id );

    $count = (int) $product->get_meta( '_click_counter' );
    $count++;

    $product->update_meta_data( '_click_counter', $count );
    $product->save();
}

add_action( 'woocommerce_add_to_cart', 'count_add_to_cart_clicks', 90, 4 );
function count_add_to_cart_clicks( $cart_item_key, $product_id, $quantity, $variation_id = null ){

    if ( did_action( 'woocommerce_add_to_cart' ) === 1 ) {

        add_to_cart_click_counter( $product_id );

        if ( $variation_id > 0 ) {
        add_to_cart_click_counter( $variation_id );
        }
    }
}

add_filter('manage_edit-product_columns', 'product_click_count_column' );
function product_click_count_column( $columns ) {

    $columns['click_counter'] = __( 'Clicks & Sold', 'woocommerce' );
    return $columns;
}

add_action( 'manage_product_posts_custom_column', 'product_click_count_column_content', 10, 2 );
function product_click_count_column_content( $column, $post_id ) {

        global $product;
        
        if ( $column === 'click_counter' ) { 
        
            if ( $product->get_type() == 'auction' ) return;
            $sold_x_times = get_post_meta( $product->get_id(), 'total_sales', true );
            echo '<span>Sold </span>' . $sold_x_times . '</br><span>Clicks </span>' . (int) $product->get_meta( '_click_counter' );
            echo '<div style="margin-top:20px"></div>';
        
        // everything works except the line below = what I need is statistics based on clicks / sales
        // echo get_post_meta( $product->get_id(), '_click_counter' / 'total_sales', true );
    }
}
