按 id 或 sku 扩展后端订单列表中的产品项目搜索

Question

我正在尝试使用中的以下代码来启用按天空和 ID 搜索 woocommerce 订单，sku 对我来说是重要的部分。

   add_filter( 'woocommerce_shop_order_search_fields', function ($search_fields ) {
    $posts = get_posts(array('post_type' => 'shop_order'));

    foreach ($posts as $post) {
        $order_id = $post->ID;
        $order = new WC_Order($order_id);
        $items = $order->get_items();

        foreach($items as $item) {
            $product_id = $item['product_id'];
            $search_sku = get_post_meta($product_id, "_sku", true);
            add_post_meta($order_id, "_product_sku", $sku);
            add_post_meta($order_id, "_product_id", $product_id);
        }
    }

    return array_merge($search_fields, array('_product_sku', '_product_id'));
});

当我将其添加到我的 functions.php 时，出现以下错误：

Array() expects parameter 1 to be a valid callback, function 'woocommerce_shop_order_search_order_total' not found or invalid function name in /var/sites/s/silverfx.co.uk/public_html/wp-includes/plugin.php on line 235

Warning: array_merge(): Argument #1 is not an array in /var/sites/s/silverfx.co.uk/public_html/wp-content/themes/SilverFx-Theme/functions.php on line 156

Warning: array_map(): Argument #2 should be an array in /var/sites/s/silverfx.co.uk/public_html/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-post-types.php on line 1533

Warning: array_map(): Argument #2 should be an array in /var/sites/s/silverfx.co.uk/public_html/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-post-types.php on line 1557

Warning: implode(): Invalid arguments passed in /var/sites/s/silverfx.co.uk/public_html/wp-content/plugins/woocommerce/includes/admin/class-wc-admin-post-types.php on line 1557

我假设因为这已经有 1 年的历史了，而且 woocommerce 在那段时间经历了一些重大变化，所以这段代码需要以某种方式更新，但是我对 woocommerce 的经验不足，无法识别出了什么问题。

如果有人能够确认我在正确的道路上，或者就我可能需要做什么提供指导/建议，那就太好了。

谢谢

虽然 woocommerce_shop_order_search_fields 过滤器钩子在后端订单列表中扩展搜索，但您需要添加一些 post_meta 字段以根据 id 或 sku 搜索订单商品。

作者 在 产品 sku add_post_meta() 中犯了一个错误。您需要用 $search_sku 替换未定义的 $sku 变量，我认为.

更新： 经过一番思考并搜索了此代码段中使用的 wordpress 函数后，我想我找到了解决方案。

这是与 to add_post_meta() function 问题相关的更新代码：

add_filter( 'woocommerce_shop_order_search_fields', function ($search_fields ) {
    $orders = get_posts( array( 'post_type' => 'shop_order' ) );

    foreach ($orders as $order_post) {
        $order_id = $order_post->ID;
        $order = new WC_Order($order_id);
        $items = $order->get_items();

        foreach( $order->get_items() as $item_id => $item_values ) {
            if ( version_compare( WC_VERSION, '3.0', '<' ) ) {
                $product_id = $item_values['product_id'];
            } else {
                $product_id = $item_values->get_product_id();
            }
            $search_sku = get_post_meta($product_id, "_sku", true);
            add_post_meta($order_id, "_product_id", $product_id, true); //  <= ## Here ##
            add_post_meta($order_id, "_product_sku", $search_sku, true); // <= ## Here ##
        }
    }
    return array_merge($search_fields, array('_product_id', '_product_sku'));
} );

缺少可选参数，当设置为 true.

时指定 value 不是数组

现在应该可以了。

您可以在搜索结果过滤器中进行附加查询。此代码还将搜索产品元数据，如属性等。

function woocommerce_shop_order_search_results_with_product_info( $order_ids, $term, $search_fields ) {
global $wpdb;

if ( ! empty( $search_fields ) ) {
    $order_ids = array_unique(
        array_merge(
            $order_ids,
            $wpdb->get_col(
                $wpdb->prepare(
                    "SELECT DISTINCT order_id
                            FROM kn_woocommerce_order_items
                            RIGHT JOIN (
                                SELECT kn_woocommerce_order_itemmeta.order_item_id, kn_postmeta.meta_value
                                FROM kn_woocommerce_order_itemmeta 
                                LEFT JOIN kn_postmeta ON kn_woocommerce_order_itemmeta.meta_value = kn_postmeta.post_id
                                WHERE kn_woocommerce_order_itemmeta.meta_key = '_product_id' AND kn_postmeta.meta_value LIKE %s
                            ) AS order_items ON order_items.order_item_id = kn_woocommerce_order_items.order_item_id",
                    '%' . $wpdb->esc_like( wc_clean( $term ) ) . '%'
                )
            )
        )
    );
}

    return $order_ids; 
}

add_filter( 'woocommerce_shop_order_search_results', 'woocommerce_shop_order_search_results_with_product_info', 999, 3 );
