wordpress - woocommerce 在前端按库存和缺货对产品进行排序

Question

我想首先在产品类别中显示库存产品，或者如果可能的话在任何地方显示，然后我想在 Woocommerce 中显示缺货产品之后

其实有很多产品没有数量但是有库存，所以需要检查库存状态，但我更喜欢先有更多的数量

在这种情况下如何强制当前排序？非常感谢

使用此代码:

<?php

/**
 * Order product collections by stock status, instock products first.
 */
class iWC_Orderby_Stock_Status
{

    public function __construct()
    {
        // Check if WooCommerce is active
        if (in_array('woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) {
            add_filter('posts_clauses', array($this, 'order_by_stock_status'), 2000, 2);
        }
    }

    public function order_by_stock_status($posts_clauses, $wp_query)
    {
        global $wpdb;
        // only change query on WooCommerce loops
        if (false === is_admin() && $wp_query->is_post_type_archive('product')) {
            $posts_clauses['join'] .= " INNER JOIN $wpdb->postmeta istockstatus ON ($wpdb->posts.ID = istockstatus.post_id) ";
            $posts_clauses['orderby'] = " istockstatus.meta_value ASC, " . $posts_clauses['orderby'];
            $posts_clauses['where'] = " AND istockstatus.meta_key = '_stock_status' AND istockstatus.meta_value <> '' " . $posts_clauses['where'];
        }
        return $posts_clauses;
    }
}

new iWC_Orderby_Stock_Status;

?>
