我想显示在库存产品首先在产品类别或如果可能在任何地方，然后我想显示出的库存产品后，他们在WooCommerce
实际上有很多产品没有数量号，但有库存，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，如何为当前排序设置强制？非常感谢你
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 $posts_clauses;
}
}
new iWC_Orderby_Stock_Status;
?>
我在搜索中看到的其他代码有时可以在商店页面中创建404错误，我编辑了这个：
add_filter('posts_clauses', 'avn_order_by_stock_status');
function avn_order_by_stock_status($posts_clauses) {
global $wpdb;
if (is_woocommerce() && (is_shop() || is_product_category() || is_product_tag() || is_product_taxonomy())) {
if(is_shop()){
$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;
}
