我想按照与给定的post id数组相同的顺序对查询结果进行排序。E、 g.我有：

$arrayPostsIds = array(30,5,17,10);

我想按这个顺序得到帖子。所以在尝试之后this:

add_filter(\'posts_orderby\', \'edit_posts_orderby\');

function edit_posts_join_paged($join_paged_statement) {
    global $arrayPostsIds_id;
    $join_paged_statement = \'FIELD(ID,\'.implode(\',\',$arrayPostsIds).\')\';
    return $join_paged_statement;   
}

然后我得到新的结果，它应该符合上面的顺序：

$temp = $wp_query; // assign ordinal query to temp variable for later use  
$wp_query = null;
$wp_query = new WP_Query( array( \'post__in\' => $arrayPostsIds, \'ignore_sticky_posts\' => true, \'date_query\' => $date_query ) ); 

但我得到了结果ordered by ID, 所以它没有保持理想的秩序。我忘了什么吗？

$wp_query = new WP_Query( 
  array(
     \'post__in\' => $arrayPostsIds,
     \'ignore_sticky_posts\' => true, 
     \'date_query\' => $date_query ,
    \'orderby\' => \'post__in\',
  ) 
);
