adjacent_post_link filter hook missing $post

wp-includes/link-template.php, line 1369

apply_filters( "{$adjacent}_post_link", $format, $link );

should be:
apply_filters( "{$adjacent}_post_link", $format, $link, $post );

Users may want to do replacement in post link that requires information about the post. For instance, inserting the author into the link. Example, if the post link format contains "%author" the following code will inject the author name of the next/previous post into it.

function advent_author_format_link($format, $link, $post) {

$author = get_userdata($post->post_author);
$format = str_replace('%author', $author->display_name, $format);
return $format;
return array(

'format' => $format,
'post' => $post,


add_action('previous_post_link', 'advent_author_format_link', 10, 3);
add_action('next_post_link', 'advent_author_format_link', 10, 3);
