Display Post Author Link above the loop

Question

I am trying to display current post author link above the loop (before loop starts) with this tag the_author_posts_link() but it's not displaying the author post link. Anyone please help me.

Edited question:

So I want author post links like this

September 17th, 2008 by (here will be author name with post link)

Like

September 17th, 2008 by Jatin Soni

This is the author meta I belive

Answer 1

It make use of global variable $post to get author id of current post. Using that this function returns the author url.

Note -

Make sure you put this in condition ( is_single() ) so it only print author url on single.php.

<?php echo get_author_posts_url( $post->post_author ); ?>

Update -

<?php $username = get_userdata( $post->post_author ); ?>    
<a href="<?php echo get_author_posts_url( $post->post_author ); ?>"><?php echo $username->user_nicename; ?></a>

^{This will work, but I'll update my answer if I found more efficient method.}

Answer 2

You have to use the function in the loop.

Else it won't output anything.

Edit

First, you might want to retrieve a list of links to all authors.

All authors:

You can use wp_list_authors() for this:

$authors = wp_list_authors( array(
     'echo'       => false
    ,'feed_image' => false
    ,'feed'       => true
) );
// do something with ...
// $authors;

This leaves you with a list of all authors and is similar to what @amit wrote.

A single author link

This is similar to what @amit wrote.

Setup the user data with setup_userdata( $author_id );. The $author_id can be retrieved with the $post global like this:

global $post;
$author = setup_userdata( $post->post_author );
echo get_author_posts_url( $post->post_author, $author->user_nicename ); 

Answer 3

<?php 
   $author_id=$authors_post->post_author;
   $author_name = get_userdata($author_id)- >display_name; 
  ?>
   <a href="<?php echo get_author_posts_url(    get_the_author_meta( $author_id ) ); ?>"><?php.    echo $author_name; ?></a>
