Question

在Woocommerce中，我在Woocommerce默认价格字段下的“定价”部分的管理员中设置了2个自定义字段：保证金率和购买价格。

我正在尝试根据以下计算方法自动更新产品价格（正常价格字段）：

        List<string> fileExtensions = new List<string>
        {
            ".mp4",
            ".mov",
            "..."
        };

        var files = Directory.EnumerateFiles(sourceDIR.Text, "*.*", SearchOption.AllDirectories).Where(s => s.EndsWithFromList(fileExtensions));

感谢您的帮助。

您应该添加始终在问题中添加用于其他定价字段的代码。

下面的代码是：

显示并保存2个自定义字段：保证金率和购买价格。
保存根据这两个自定义字段值计算出的新产品价格。

之前，您需要删除正在生成2个自定义字段的代码（因为它将被我的替换）。

// Adding and displaying additional product pricing custom fields
add_action( 'woocommerce_product_options_pricing', 'additional_product_pricing_option_fields', 50 );

    global $post;

    echo '</div><div class="options_group pricing show_if_simple show_if_external show_if_composite">';

        // If the active price is different from the calculated new price
        if( $new_price !== $active_price ) {
            // Update regular price and active price with new calculated price
            $product->set_price( $new_price );

    }

// Saving and calculating prices
add_action( 'woocommerce_admin_process_product_object', 'update_product_meta_data', 100, 1 );
function update_product_meta_data( $product ) {

    // Saving "Rate margin" and "Purchase_price" custom fields values
    saving_rate_margin_and_purchase_price( $product ); // <== To be removed if not used with the first function

    // Calculate and save product price from the "Rate margin" and the "Purchase price" custom fields
    calculate_and_save_new_product_price( $product );
}

代码进入您的活动子主题（活动主题）的function.php文件中。经过测试可以正常工作。
