我更新了数据库。更新后，我在 Woocommerce 中遇到了重复的产品——即使我在数据库中没有重复的产品。
我删除了 transient ，但它没有修复。如果您指导我如何修复它，我将不胜感激。
提前致谢。

最佳答案
事实上，我有两个问题。第一个问题是产品列表页面中的重复产品，我发现问题与以下代码有关:
add_filter('posts_clauses', 'order_by_stock_status');
function order_by_stock_status($posts_clauses) {
global $wpdb;
// only change query on WooCommerce loops
if ( is_woocommerce() && (is_shop() || is_product_category() || is_product_tag() || is_product_taxonomy())) {
$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;
}
!is_admin()到条件，然后它固定。我也有另一个同样的问题，但这次是在类别页面。对于这种情况，我检查了插件，我发现 xforwoocommerce(过滤器)插件以不同的价格制作了重复的产品! :| (不知道为什么!)
我禁用了它并修复了它，但我认为根本原因是上面的代码。
