count_user_posts


count_user_posts 是一个用来获取用户文章数量的WordPress函数

function?count_user_posts(?$userid,?$post_type?=?'post'?)?{
????global?$wpdb;
?
????$where?=?get_posts_by_author_sql(?$post_type,?true,?$userid?);
?
????$count?=?$wpdb->get_var(?"SELECT?COUNT(*)?FROM?$wpdb->posts?$where"?);
?
????/**
?????*?Filter?the?number?of?posts?a?user?has?written.
?????*
?????*?@since?2.7.0
?????*?@since?4.1.0?Added?`$post_type`?argument.
?????*
?????*?@param?int????$count?????The?user's?post?count.
?????*?@param?int????$userid????User?ID.
?????*?@param?string?$post_type?Post?type?to?count?the?number?of?posts?for.
?????*/
????return?apply_filters(?'get_usernumposts',?$count,?$userid,?$post_type?);
}

从 4.1 开始添加了一个文章类型参数,具体用法如下:

count_user_posts(?$userid,?$post_type?)

参数:

$userid 用户的ID,必填

$post_type 文章类型,默认为 post,选填

比如我调用 ID 为 23 的这个用户的 question 这个文章类型的数量:

PHP?echo?count_user_posts(?23,?'question'?)??>
