Php 获取自定义计算作为批量订单操作

我想让订单总数符合计算公式

我有司机，他们的工资是按订单计算的。他们交付有酬和无酬订单。因此，他们向客户收取未付的cod付款。在一天结束时，我计算从金额中扣除他们的工资后，我必须向他们收取多少。（这种情况每天都会发生）

公式为[（'cod'订单总数）-（已交付订单数量）x 1.5]

这是一个例子

假设我们已收到3份订单，司机已将其收货交付。。因此，在一天结束时，司机必须把现金带回来。。在这里，我想知道扣除他的工资后，我要向他收取多少钱

order A : total = 50 : payment method /cod
order B : total = 10 : payment method /cod
order C : total = 40 : payment method /credit card

    the calculation = [ 'cod' orders totals - (selected orders number ) x 1.5 ]

the calculation = [ ( 50 + 10 ) - (3 ) x 1.5 ] = 55.5

结果是（55.5）是我必须向司机收取的金额

我不知道这是否必须在同一个管理命令页或一个新的页面。。

我设想在WC的订单管理部分或单独的页面上，我可以从我想要进行计算的订单列表和我选择的批量操作下拉框中检查订单，例如[CALCULATION 1]，然后显示结果

您可以使用以下代码，允许您在批量订单选择中计算您问题中定义的从驱动程序处收取的金额：

// Display the custom actions on admin Orders bulk action dropdown
add_filter( 'bulk_actions-edit-shop_order', 'orders_bulk_action_delivery_collect_calc' );
function orders_bulk_action_delivery_collect_calc( $bulk_actions ) {
    $bulk_actions['delivery-collect'] = __( "Calculate delivery collect", 'woocommerce' );

    return $bulk_actions;
}

// Process the bulk action from selected orders
add_filter( 'handle_bulk_actions-edit-shop_order', 'delivery_collect_calc_bulk_action_edit_shop_order', 10, 3 );
function delivery_collect_calc_bulk_action_edit_shop_order( $redirect_to, $action, $post_ids ) {

    if ( $action === 'delivery-collect' ) {
        $order_numbers    = []; // Initializing
        $cod_orders_total = 0; // Initializing
        $salary_per_order = 1.5;

        foreach ( $post_ids as $post_id ) {
            // Get Order status
            $order = wc_get_order( $post_id );

            if( $order->get_payment_method() === 'cod' ) {
                $cod_orders_total += (float) $order->get_total();
            }

            // Order status change to "completed" (To enable uncomment the line below)
            // $order->update_status("completed");

            $order_numbers[] = $order->get_order_number(); // Adding processed order numbers to an array
        }

        $orders_count      = count( $order_numbers );
        $amount_to_collect = $cod_orders_total - ( $orders_count * $salary_per_order );


        // Adding the right query vars to the returned URL
        $redirect_to = add_query_arg( array(
            'collect_action'     => $action,
            'processed_count'    => $orders_count,
            'proc_order_nums'      => implode( ',', $order_numbers ),
            'amount_to_collect'  => $amount_to_collect,
        ), $redirect_to );
    }
    return $redirect_to;
}

// Display the results notice from bulk action on orders
add_action( 'admin_notices', 'set_delivery_collect_bulk_action_admin_notice' );
function set_delivery_collect_bulk_action_admin_notice() {
    global $pagenow;

    if ( 'edit.php' === $pagenow && isset($_GET['post_type']) && 'shop_order' === $_GET['post_type']
    && isset($_GET['collect_action'])  && isset($_GET['processed_count'])
    && isset($_GET['proc_order_nums']) && isset($_GET['amount_to_collect']) ) {

        $count_ids = intval( $_GET['processed_count'] );
        $amount    = floatval( $_GET['amount_to_collect'] );
        $currency  = get_woocommerce_currency_symbol();

        printf( '<div class="notice notice-success fade is-dismissible"><p>' .
            _n( "On %s selected order, the calculated amount to collect is %sProcessed order Id is %s",
                "On the %s selected orders, the calculated amount to collect is %sProcessed orders Ids are %s.",
            $count_ids, "woocommerce" ) . '</p></div>',
            $count_ids,
            '<code>' . number_format_i18n($amount, 2) . '</code> (' . $currency . ').</p><p>',
            '<code>' . $_GET['proc_order_nums'] . '</code>'
        );
    }
}

代码进入活动子主题（或活动主题）的function.php文件。测试和工作

此自定义批量操作（在订单列表批量操作下拉列表上）：

可驳回消息框中的计算结果：

@LoicTheAztec你能帮我做点什么吗this@Ibrahim我已经更新了我的代码和屏幕截图…它在消息中包含已处理的订单…您甚至可以同时将订单状态更改为“已完成”…@Ibrahim我刚刚更新了代码以获取订单号而不是ID…如果您想更新订单状态，请取消注释行

/$order->update_status（“completed”）删除

…无法获取链接，因为数据通过URL传递（get方法）
