Woocommerce函数set_total_sales()未设置并将total_sales保存到数据库

我正在处理woocommerce中的儿童主题。在一个函数中, 我尝试使用默认的get_total_sales()和set_total_sales()来增加总销售额并保存从AJAX调用时(单击按钮下载时)的销售额。

function download_count_callback(){

    //get product id from AJAX POST
    $productid = $_POST['productid'];

    //get product by id
    $product = wc_get_product( $productid );

    //get the total sales number
    $downloadcount = $product->get_total_sales();
    error_log ("NUMBER was : ".$downloadcount );

    //add 1 to total sales
    $downloadcount += 1;
    error_log ("NUMBER should become : ".$downloadcount );

    //get the renewed total sales number
    $product->set_total_sales($downloadcount);
    error_log ("NUMBER NOW : ".$product->get_total_sales());

    wp_die();
}

服务器日志如下所示：

[23-Feb-2020 12:44:44 UTC] NUMBER was : 0
[23-Feb-2020 12:44:44 UTC] NUMBER should become : 1
[23-Feb-2020 12:44:44 UTC] NUMBER NOW : 1

看起来不错, 但没有…下载计数未保存到数据库中。当我刷新页面时,

get_total_sales()将返回到0。

这有什么问题吗？

这有什么不同吗？

function download_count_callback(){

    //get product id from AJAX POST
    $productid = $_POST['productid'];

    //get product by id
    $product = wc_get_product( $productid );

    //get the total sales number
    $downloadcount = $product->get_total_sales();
    error_log ("NUMBER was : ".$downloadcount );

    //add 1 to total sales
    $downloadcount += 1;
    error_log ("NUMBER should become : ".$downloadcount );

    //get the renewed total sales number
    $product->set_total_sales($downloadcount);

    $product->save();
    error_log ("NUMBER NOW : ".$product->get_total_sales());

    wp_die();
}
