在 Woocommerce 中更改延期交货商品的订单状态

Question

我正在使用 WordPress 和 WooCommerce 配置网上商店。我安装了一个名为Woo Multi Order Creator 的插件。所做的是，每当订购超过 1 件商品时，它将主订单分为多个订单，每个购买的商品一个订单。

现在，如果每个订单中的商品包含值为“Backordered”的元键，我想做的是让它改变每个订单的订单状态。

例如，如果购买了产品 A 和产品 B。产品 A 缺货，因此有 {$wpdb->prefix}woocommerce_order_itemmeta.meta_key = 'Backordered' 并且产品 B 将有库存，并且它没有用于延期交货的元密钥。

现在，插件将此订单分为两个订单，每个购买的商品一个。我希望它进一步做的是查看每个新订单中包含的项目是否具有延期交货的元键，如果它已经将每个订单的订单状态更改为“等待”。

插件代码：

它在第 253 行将订单状态更改为正在处理。

我猜应该在这里添加一些代码以使其将订单状态更改为等待，如果订单中的项目具有延期交货的元密钥。

我希望比我非常有限的知识更专业的人能来帮助我。

Answer 1

这是一个钩子函数，当订单获得“处理”状态时触发。

在函数内部，我们通过简单的 SQL 查询从订单 ID 中查找“延期交货”的订单商品。

如果发现“延期交货”商品，我们会将订单状态更改为“暂停”（您的情况下正确的订单状态）。

代码：

add_action('woocommerce_order_status_processing', 'pending_back_orders_to_on_hold', 60, 2 );
function pending_back_orders_to_on_hold( $order_id, $order ) {
    global $wpdb;

    // The SQL query for Order items in backorder
    $results = $wpdb->get_col( "
        SELECT woim.meta_value FROM {$wpdb->prefix}woocommerce_order_itemmeta as woim
        INNER JOIN {$wpdb->prefix}woocommerce_order_items as woi ON woim.order_item_id = woi.order_item_id
        WHERE woi.order_id = '$order_id' AND woim.meta_key = 'Backordered'
    " );
    
    // If an item is 'Backordered' we change the order status to "on-hold"
    if(reset($results) > 0)
        $order->update_status('on-hold');
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。

经过测试并且有效。

更新 （与您的评论有关）

如果您想为此目的更改插件内的代码，您将替换第 253 行：

$order->update_status('processing');

通过以下代码：

$line_item_ids = array_keys( $order->get_items() );
$backordered = wc_get_order_item_meta( reset($line_item_ids), 'Backordered', true );
$changed_status = $backorders > 0 ? 'on-hold' : 'processing';
$order->update_status( $changed_status ); 

应该可以，但这不是一个好习惯。
