Guest author's post not display in author template

Question

I am using this filter to display guest author on post, but i want guest author's posts to appear in the author.php template also.

This is my guest author code (inside functions.php).

<?php
add_filter( 'the_author', 'guest_author_name' );
add_filter( 'get_the_author_display_name', 'guest_author_name' );
function guest_author_name( $name ) {
    global $post;

    $author = get_post_meta( $post->ID, 'guest-author', true );

    if ( $author )
        $name = $author;
    return $name;
}
?>

...and here is the author template: http://codex.wordpress.org/Author_Templates#Sample_Template_File

Answer 1

Create a new user with a role such as subscriber so they cant do anything in the backend, and assign the post to that user. Doing this would be a lot easier than the hours of custom coding needed to get things working using your system.
