我正在为EDD构建一个插件，它添加了一个带有复选框选项meta\\u key的自定义元框_xy_global_product.

到目前为止，一切顺利。

在前端，我尝试过滤将此meta\\u键设置为1的帖子。

这是我的代码：

        $args = [
            \'meta_query\' => [
                [
                    \'key\'   => \'_xy_global_product\',
                    \'value\' => 1
                ]
            ],
            \'post_type\' => \'download\', // Custom post type, created by Easy Digital Downloads.
            \'posts_per_page\' => -1
        ];
        $global_products = new WP_Query($args);

$global_products 返回空数组，因为查询是由WP_Query() 如下所示：

SELECT   wp_posts.* FROM wp_posts  INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.post_id ) WHERE 1=1  AND wp_posts.ID NOT IN (4816,4473,4163) AND ( 
  ( wp_postmeta.meta_key = \'_xy_global_product\' AND wp_postmeta.meta_value = \'1\' )
) AND wp_posts.post_type = \'download\' AND (wp_posts.post_status = \'publish\' OR wp_posts.post_status = \'cancelled\' OR wp_posts.post_status = \'edd_subscription\' OR wp_posts.post_status = \'refunded\' OR wp_posts.post_status = \'failed\' OR wp_posts.post_status = \'revoked\' OR wp_posts.post_status = \'abandoned\' OR wp_posts.post_status = \'processing\' OR wp_posts.post_status = \'active\' OR wp_posts.post_status = \'inactive\' OR wp_posts.post_status = \'preapproval_pending\' OR wp_posts.post_status = \'preapproval\' OR wp_posts.post_status = \'private\') GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC

预期结果（在我的测试用例中）将是ID为4163的帖子。然而，在制作时，它可能是一个职位列表。

以下部分阻止查询成功：wp_posts.ID NOT IN (4816,4473,4163) 因为当我删除它时，它会返回预期的结果。

如何在查询中删除此部分？

public function unhide_downloads()
{
    if (function_exists(\'edd_hide_download\')) {
        remove_action(\'pre_get_posts\', [edd_hide_download(), \'pre_get_posts\'], 9999);
    }
}
