WordPress: get author info from post id
提问by superUntitled
Or even the author id from the post id. I am trying to return the author meta (author page link and avatar) in the sidebar of a single post page (outside of the post loop). What is the best way to do this? I am using a custom function (see below) to return the post id, but am not sure what function to call next.
甚至是来自帖子 ID 的作者 ID。我试图在单个帖子页面的侧边栏中（帖子循环之外）返回作者元数据（作者页面链接和头像）。做这个的最好方式是什么？我正在使用自定义函数（见下文）返回帖子 ID，但不确定接下来要调用什么函数。
function this_post_id() {
global $wp_query;
$thePostID = $wp_query->post->ID;
return $thePostID;
}

I figured it out.
我想到了。
<?php $author_id=$post->post_author; ?>
<img src="<?php the_author_meta( 'avatar' , $author_id ); ?> " width="140" height="140" class="avatar" alt="<?php echo the_author_meta( 'display_name' , $author_id ); ?>" />
<?php the_author_meta( 'user_nicename' , $author_id ); ?>

If you want it outside of loop then use the below code.
如果您想在循环之外使用它，请使用以下代码。
<?php
$author_id = get_post_field ('post_author', $cause_id);
$display_name = get_the_author_meta( 'display_name' , $author_id );
echo $display_name;
?>
