也许不是最优雅的解决方案

 

$authorPost = get_posts(array(\'author\' => 1));foreach ($catPost as $post) {
    setup_postdata($post);
    $ids[] = get_the_ID();
}
$idList = implode(",", $ids); //turn the array into a comma delimited list

$meta_key = \'post_view\';
$allview = $wpdb->get_var($wpdb->prepare("
                                  SELECT sum(meta_value) 
                                  FROM $wpdb->postmeta 
                                  WHERE meta_key = %s 
                                  AND post_id in (" . $idList . ")", $meta_key));
echo \'
user 1 All posts View Count\'.$allview .\'
\';
