我有一个非常奇怪的问题，我被卡住了。我希望单个页面显示post\\u状态为publish and future的帖子。因此，我将此代码添加到我的函数中。我的主题中的php：
function display_future_posts() {
global $wp_query;
if( !is_admin() && $wp_query->is_main_query() && $wp_query->is_single()) {
$wp_query->set( \'post_status\', array(\'future\', \'publish\', \'draft\') );
}
}
add_action(\'pre_get_posts\', \'display_future_posts\');
这将成功更改查询。但当我没有以管理员身份登录时，仍然会看到404页面。所以我跟踪了db查询。下面是我在调用print\\u r（$wpdb->querys）时发现的内容；：
[16] => Array
(
[0] => SELECT wp_posts.* FROM wp_posts WHERE 1=1 AND ( ( YEAR( post_date ) = 2014 AND MONTH( post_date ) = 9 ) ) AND wp_posts.post_name = \'my-life\' AND wp_posts.post_type = \'post\' AND (wp_posts.post_status = \'publish\' OR wp_posts.post_status = \'future\') ORDER BY wp_posts.post_date DESC
[1] => 0.000303030014038
[2] => require(\'wp-blog-header.php\'), wp, WP->main, WP->query_posts, WP_Query->query, WP_Query->get_posts
)
[17] => Array
(
[0] => SELECT post_id FROM wp_postmeta, wp_posts WHERE ID = post_id AND post_type = \'post\' AND meta_key = \'_wp_old_slug\' AND meta_value = \'my-life\' AND YEAR(post_date) = 2014 AND MONTH(post_date) = 9
[1] => 0.000878095626831
[2] => require(\'wp-blog-header.php\'), require_once(\'wp-includes/template-loader.php\'), do_action(\'template_redirect\'), call_user_func_array, wp_old_slug_redirect
)
[18] => Array
(
[0] => SELECT ID FROM wp_posts WHERE post_name LIKE \'my-life%\' AND post_type IN (\'post\', \'page\', \'attachment\') AND YEAR(post_date) = 2014 AND MONTH(post_date) = 9 AND post_status = \'publish\'
[1] => 0.00031304359436
[2] => require(\'wp-blog-header.php\'), require_once(\'wp-includes/template-loader.php\'), do_action(\'template_redirect\'), call_user_func_array, redirect_canonical, redirect_guess_404_permalink
)
因此，执行了我的查询，但wp中的函数wp\\u old\\u slug\\u redirect（）包含/query。调用php，函数is\\u 404（）返回true。所以Wordpress试图找到一个旧的slug（当然不存在），失败后重定向到404。
当我调用print\\u r（$wp\\u query）时；在标题中。我的主题php似乎成功修改了查询，但奇怪的是没有返回任何结果。至少[帖子]为空。当我直接在MySQL服务器上运行[请求]时，我得到的正是我想要的结果。

我没脑子了。我做错了什么？我错过了什么。
我希望这个问题不要太具体，它对其他人有帮助。
谢谢Ole
