WooCommerce 按产品元查询订单项

问题描述

这有点奇怪，但我很难找到如何做到这一点的答案:

This is a bit of an odd one, but I'm having trouble finding an answer for how to do this:

我正在尝试创建一个自定义查询，以获取 WooCommerce 订单中包含的所有产品(及其元数据).

I'm attempting to create a custom query that gets all the products (and their meta) which are contained within a WooCommerce order.

例如，假设我有这些订单待处理:

For example, let's say I have these orders pending:

• 产品 1
• 产品 2
• 产品 3

• 产品 4
• 产品 5
• 产品 6

我的目标是根据这些订购的产品创建一个列表，该列表按产品的元进行排序.像这样:

My goal is to create a list based off these ordered products, which is ordered by the product's meta. Something like this:

• 产品 1
• 产品 3
• 产品 4

但同样，这些只能是订单中的产品(包括数量).

But again, these would only be products (including their quantities) that sit within an order.

我面临的问题是订购商品"和订单项元"存储在数据库中的数据非常有限，并且不会显示与产品相关的所有信息.因此，换句话说，我没有找到一种方法来获取创建循环以创建我的列表所需的信息.

The problem I'm facing is that "Order Items" and "Order Item Meta" as stored in the database are quite limiting and do not display all the information associated with a product. So in other words, I'm not finding a way to get to the info I need to create the loop to create my list.

我的数据库技能有限，因此不胜感激！

My DB skills are limited so ideas would be appreciated!

add_filter( 'woocommerce_shop_order_search_fields', 'woocommerce_shop_order_search_product_cat' );

function woocommerce_shop_order_search_product_cat( $search_fields ) {

$args = array(
    'post_type' => 'shop_order'
    );

$orders = new WP_Query($args);

if($orders->have_posts()) {
        while($orders->have_posts()) {
        $post = $orders->the_post();
        $order_id = get_the_ID();
        $order = new WC_Order($order_id);
        $items = $order->get_items();
        foreach($items as $item) {
            $product_cats = wp_get_post_terms( $item['product_id'], 'product_cat' );
            foreach($product_cats as $product_cat) {
                add_post_meta($order_id, "_product_cat", $product_cat->name);
            }
        }
    }
};

$search_fields[] = '_product_cat';

return $search_fields;

}
