wordpress - Wordpress get_posts 总是返回 null，对于任何帖子类型，post_status=all 等

问题描述

一直在扯我的头发，无法在一个简单的查询中返回任何帖子：

get_posts();

get_posts([
    'post_type' => 'meetings',
    'post_status' => 'any'
]);

$posts = get_posts([
    'post_type'        => 'meetings',
    'post_status'      => 'any',
    'ping_status'      => 'any',
    'suppress_filters' => true,
    'post_parent'      => null
]);

当我创建一个新的“会议”类型的帖子时，我可以确认它是以这种状态创建的：

{
   "ID":100,
   "post_author":"1",
   "post_date":"2020-08-12 16:26:45",
   "post_date_gmt":"2020-08-12 16:26:45",
   "post_content":"",
   "post_title":"Test",
   "post_excerpt":"",
   "post_status":"publish",
   "comment_status":"closed",
   "ping_status":"closed",
   "post_password":"",
   "post_name":"test-2",
   "to_ping":"",
   "pinged":"",
   "post_modified":"2020-08-12 16:43:43",
   "post_modified_gmt":"2020-08-12 16:43:43",
   "post_content_filtered":"",
   "post_parent":0,
   "guid":"http:\\/\\/esh.localhost\\/?post_type=meetings&p=100",
   "menu_order":0,
   "post_type":"meetings",
   "post_mime_type":"",
   "comment_count":"0",
   "filter":"raw"
}

这是注册此自定义 post_type 的代码：

register_post_type( 'meetings', [
    'show_ui' => true,
    'labels'  => array(
        'name' => 'Meetings',
        'singular_name' => 'Meeting',
        'add_new' => 'New Meeting',
        'all_items' => 'All Meetings',
        'add_new_item' => 'New Meeting',
        'edit_item' => 'Edit Meeting',
        'new_item' => 'New Meeting',
        'view_item' => 'View Meeting',
        'search_items' => 'Search Meetings',
        'not_found' =>  'No meetings found',
        'not_found_in_trash' => 'No Meetings found in trash',
        'parent_item_colon' => 'Parent Meeting:',
        // 'parent' => 'eSupport',
        // 'menu_name' => 'eSupport'
    ),
    'show_in_graphql' => true,
    'hierarchical' => true,
    'graphql_single_name' => 'meeting',
    'graphql_plural_name' => 'meetings',
    'show_in_menu' => 'esh-sections'
]);

那么有了这些帖子细节，谁能明白为什么 get_posts 可能一直返回一个空集？即使对于常规帖子（'post_type' => 'all'），它仍然是空的。

如果有帮助，这里是确切的代码和输出：

$posts = get_posts([
    'post_type'        => 'meetings',
    'post_status'      => 'any',
    'posts_per_page'   => -1
]);

dlog("Post type exists?", post_type_exists( 'meetings' ) );
dlog("posts", json_encode($posts));

输出：

[Wed Aug 12 13:09:49.732013 2020] [php7:notice] [pid 4371] [client ::1:60535] \nPost type exists?, referer: http://localhost:3000/dashboard

解决方案

啊，抱歉，我有一个过滤返回的操作：

add_action('pre_get_posts', 'ESH\Meetings::get_meetings_by_owner' );

禁用这些可以让我看到帖子。对困惑感到抱歉！
