返回多个用户的文章总数
描述
Returns the post counts for a list of user IDs. This is an O(n) operation, so it is preferred over count_user_posts() any time more than a single count is needed.
用法
<?php count_many_users_posts( $users, $post_type, $public_only ); ?>
参数
$users
(array) (必填) List of ID values of the users whose post counts should be retrieved.
默认值: None
$post_type
(string) (可选) Name of the post type
默认值: null
$public_only
(string) (可选) Bypasses checking capabilities of current user (False) or returns posts only if they can be viewed by current user (True).
默认值: False
历史
- 3.5.0: 添加 public_only parameter
- 添加于 版本: 3.0.0
源文件
count_many_users_posts() 函数的代码位于 wp-includes/user.php.
