WordPress: get author info from post id
PhpWordpressPhp Problem Overview
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.
function this_post_id() {
global $wp_query;
$thePostID = $wp_query->post->ID;
return $thePostID;
}

Solution 1 - Php
I figured it out.
<?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 ); ?>
Solution 2 - Php
If you want it outside of loop then use the below code.
<?php
$author_id = get_post_field ('post_author', $post_id);
$display_name = get_the_author_meta( 'display_name' , $author_id );
echo $display_name;
?>
Solution 3 - Php
<?php
$field = 'display_name';
the_author_meta($field);
?>
Valid values for the $field parameter include:
- admin_color
- aim
- comment_shortcuts
- description
- display_name
- first_name
- ID
- jabber
- last_name
- nickname
- plugins_last_view
- plugins_per_page
- rich_editing
- syntax_highlighting
- user_activation_key
- user_description
- user_email
- user_firstname
- user_lastname
- user_level
- user_login
- user_nicename
- user_pass
- user_registered
- user_status
- user_url
- yim

**use this code for display Auth Name**
<?php
$auth_id = $post->post_author;
echo get_the_author_meta( 'display_name', $auth_id );
?>
Solution 5 - Php
This should work
- Post ID
$post_id = get_the_ID();
$author_id = get_post_field ('post_author', $post_id);
$display_name = get_the_author_meta( 'nickname' , $author_id );
echo $display_name;
Note: You need to use this function inside the loop.
