这就是我最后做的，因为我找不到其他方法

//Fetch all pages
$pages = get_pages( array(
        \'post_type\' => \'page\',
        \'meta_key\' => \'review_date\',
        //\'meta_key\' => \'reviewed_by_user_id\',
        \'sort_column\' => \'review_date\',
        \'sort_order\' => \'asc\'
        ));

//Fetch metadata for each page
$ordered_pages = array();
foreach ($pages as $page)
{
    $metadata = get_metadata(\'post\', $page->ID);
    $user = $metadata[\'reviewed_by_user_id\'][0];
    $date = $metadata[\'review_date\'][0];

    array_push($ordered_pages, array(
        \'ID\' => $page->ID,
        \'title\' => $page->post_title,
        \'review_date\' => $date,
        \'reviewed_by_user_id\' => $user,
        \'link\' => get_edit_post_link($page->ID),
        ));
}

//Order the pages 
$orderby_array = array();
foreach ($ordered_pages as $key => $row)
{
    $orderby_array[$key] = $row[$orderby];
}
array_multisort($orderby_array, SORT_DESC, $ordered_pages);

然后像这样在页面中循环

foreach ($ordered_pages as $page)
{
   //Some code
}

这并不漂亮，它使用get\\u metadata调用生成了很多额外的db调用，但由于它在admin中是一个很少查看的页面，所以对我来说没问题。
