php - 如何使用 WP_Query 对 post_IDs 键而不是值进行排序

Question

我像这样将 post_ids 传递给 WP_Query()

$result_post_ids = $wpdb->get_results("SELECT  DISTINCT auction_id 
                   FROM " . $wpdb->prefix . "simple_auction_log 
                   WHERE userid = $user_id 
                   order by date DESC" , ARRAY_N);

  $args = array (
            'post__in' => $result_post_ids ,
            'post_type' => 'product' ,
            'posts_per_page' => $limit ,
            'paged' => $page ,
            'tax_query' => $category_filter , //category
            'orderby' => $order_by,
            'order' => $order
        );

$result_post_ids 数组是这样的

array (size=15)
  0 => string '175' (length=3)
  1 => string '148' (length=3)
  2 => string '169' (length=3)
  3 => string '176' (length=3)
  4 => string '170' (length=3)
  5 => string '205' (length=3)
  6 => string '142' (length=3)
  7 => string '168' (length=3)
  8 => string '132' (length=3)
  9 => string '173' (length=3)
  10 => string '177' (length=3)
  11 => string '84' (length=2)
  12 => string '171' (length=3)
  13 => string '128' (length=3)
  14 => string '82' (length=2) 

所以这是我想查看的 id 的顺序，但是当将 $args 传递给 WP_Query() 时，会根据值重新排序帖子 id，因此他首先像这样显示具有磨碎器值的帖子

 177 , 176 , ...

但我想按键 0、1、2 的顺序显示，请提前提供帮助，非常感谢。

您应该将orderby 参数更改为post__in:

$args = array (
    'post__in' => $result_post_ids ,
    'post_type' => 'product' ,
    'posts_per_page' => $limit ,
    'paged' => $page ,
    'tax_query' => $category_filter ,
    'orderby' => 'post__in',  // Order by the array passed in above
    'order' => $order
);
