覆盖 Woocommerce 报告部分中的功能

Question

我需要在 WooCommerce 中自定义报告，所以我必须编辑核心文件 class-wc-report-sales-by-date.php，该文件不使用任何挂钩。

在 WC 源代码中查看：includes/admin/reports/class-wc-report-sales-by-date.php

我必须编辑 393 行，这个变量：$this->report_data->total_sales 我需要自定义 Total Sales 金额以添加另一个值。

如何覆盖 WooCommerce 这个核心文件？

Answer 1

永远不要覆盖核心文件……还有其他方法可以做到这一点。如果你查看 line 411，你有 woocommerce_admin_report_data 过滤器钩子来进行更改，这样（示例）：

add_filter( 'woocommerce_admin_report_data', 'custom_admin_report_data', 10, 1 );
function custom_admin_report_data( $report_data ){
    // HERE you make your calculations and changes
    // New amout to set (example)
    $new_calculated_amount = 100;

    // Set the new amounts for "total_sales" key
    $report_data->total_sales = $new_calculated_amount;

    // Raw data output just for testing, to get the keys and the structure of the data
    // to be removed
    echo '<pre>'; print_r($report_data); echo '</pre>';

    // Return the changed data object
    return $report_data;
}

代码进入您的活动子主题（或主题）的 function.php 文件或任何插件文件。

已测试并有效。

I have included a line of code that outputs the raw data that you should remove… It's just to see the data structure and the changes made by the function on the "total_sales" value…

原始数据输出是这样的（为您提供数据结构以更好地进行更改）:

stdClass Object
(
    [order_counts] => Array
        (
            [0] => stdClass Object
                (
                    [count] => 1
                    [post_date] => 2017-11-21 16:45:43
                )
        )
    [coupons] => Array
        (
        )
    [order_items] => Array
        (
            [0] => stdClass Object
                (
                    [order_item_count] => 1
                    [post_date] => 2017-11-21 16:45:43
                )
        )
    [refunded_order_items] => 0
    [orders] => Array
        (
            [0] => stdClass Object
                (
                    [total_sales] => 48
                    [total_shipping] => 15
                    [total_tax] => 5
                    [total_shipping_tax] => 3
                    [post_date] => 2017-11-21 16:45:43
                )
        )
    [full_refunds] => Array
        (
        )
    [partial_refunds] => Array
        (
        )
    [refund_lines] => Array
        (
        )
    [total_tax_refunded] => 0
    [total_shipping_refunded] => 0
    [total_shipping_tax_refunded] => 0
    [total_refunds] => 0
    [total_tax] => 5.00
    [total_shipping] => 15.00
    [total_shipping_tax] => 3.00
    [total_sales] => 48.00
    [net_sales] => 25.00
    [average_sales] => 3.57
    [average_total_sales] => 6.86
    [total_coupons] => 0.00
    [total_refunded_orders] => 0
    [total_orders] => 1
    [total_items] => 1
)

So as you can see you also need to make changes on the "orders" object data as you also have the "total_sales" key…
