我有一篇帖子，我需要更新它的post\\u父级。因此，我使用以下代码来更新post\\u parent值。旧的post\\u父项为844，使用query，我已使用以下命令将值更新为370：

    global $wpdb;
    $table_name = $wpdb->prefix . "posts";
    $add_plan_to_team = $wpdb->update( $table_name, array( \'post_parent\' => \'370\' ), array(\'ID\'=> \'84887\'));
    // UPDATE wp_posts SET post_parent=370 WHERE ID=84887 

在下一行中，我需要获得帖子，然后执行一些功能。我就是这样做的

     $post = get_post( 84887 );

但不是返回更新的值，而是返回旧的post\\u parent值。如下所示

WP_Post Object
(
    [ID] => 84887
    [post_author] => 2
    [post_date] => 2020-02-27 10:55:11
    [post_date_gmt] => 2020-02-27 10:55:11
    [post_content] => 
    [post_title] => MyTeam
    [post_excerpt] => 
    [post_status] => publish
    [comment_status] => closed
    [ping_status] => closed
    [post_password] => 
    [post_name] => allus-cu
    [to_ping] => 
    [pinged] => 
    [post_modified] => 2020-08-24 19:03:02
    [post_modified_gmt] => 2020-08-24 19:03:02
    [post_content_filtered] => 
    [post_parent] => 844   // This value is not correct. This should be 370
    [guid] => https://train.localdev.com/?post_type=wc_memberships_team&p=84887
    [menu_order] => 0
    [post_type] => wc_memberships_team
    [post_mime_type] => 
    [comment_count] => 0
    [filter] => db
)

我已经签入了数据库，在数据库中，post\\u parent值更新了一个。

完整的代码：

global $wpdb;
$table_name = $wpdb->prefix . "posts";
$add_plan_to_team = $wpdb->update( $table_name, array( \'post_parent\' => \'370\' ), array(\'ID\'=> \'84887\'));

if($add_plan_to_team){
    $post = get_post( $team_id, \'OBJECT\', \'db\' );
    echo \'<h1> team_updated </h1>\';
    print_r($post);            
}

请告诉我如何修理它。

$result = wp_insert_post( [
    \'ID\' => 84887,
    \'post_parent\' => 370,
] );
