How to Get the Author information Outside Loop in WP

How to Get the Author information Outside Loop in WP?

The example of Author Box can be seen in the image below;

Method 1
This method uses the WP API. This method is the best way of getting author information when you want to get it outside of the Loop.

<h3>Posts by: 
<?php 
	the_post(); // queue first post
	echo get_the_author(); // echo author
	rewind_posts(); // rewind the loop
?>
</h3>

This source code can be converted into a simpler form. Let’s see it;

<h3>Posts by: <?php the_post(); echo get_the_author(); rewind_posts(); ?></h3>

This code displays the author’s Display Name only. If you want to get the entire WP_User object, then you can use the following code:

<?php 
	the_post(); // queue first post
	$author_id = get_the_author_meta('ID');
	$curauth = get_user_by('id', $author_id);
	rewind_posts(); // rewind the loop
?>

Further, if you want to see other details about the author, then you can call any method of WP_User to get whatever author information you want. Let’s see its code.

<div id="archive-view-author">
	
	<?php 
		the_post(); // queue first post
		
		$author_id = get_the_author_meta('ID');
		$curauth = get_user_by('ID', $author_id);
		
		$user_nicename    = $curauth->user_nicename;
		$display_name     = $curauth->display_name;
		$user_description = $curauth->user_description;
		$user_email       = $curauth->user_email;
		$user_url         = $curauth->user_url;
		$user_website     = $curauth->website_name;
		$user_twitter     = $curauth->twitter;
		
		rewind_posts(); // rewind the loop
	?>
	
	<h3>Author Profile: <a href="<?php echo get_author_posts_url($author_id, $user_nicename); ?>"><?php echo $display_name; ?></a></h3>
	
	<?php if ($user_description) echo '<p>'. $user_description .'</p>'; ?>
	<?php if ($user_email)       echo get_avatar($user_email, '100'); ?>
	
	<?php if ($user_url || $user_twitter) : ?>
	
	<ul>
		
		<?php if ($user_url) : ?>
		<li>Website: <a href="<?php echo $user_url; ?>"><?php if ($user_website) : echo $user_website; else : echo $user_url; endif; ?></a></li>
		<?php endif; ?>
		
		<?php if ($user_twitter) : ?>
		<li>Twitter: <a href="https://twitter.com/<?php echo $user_twitter; ?>">@<?php echo $user_twitter; ?></a></li>
		<?php endif; ?>	
	</ul>	
	<?php endif; ?>
	
</div>

Now, you are able to get any author or any user information, even outside of the WordPress Loop.
