Next Prev Post link rendering current post thumbnail

Question

i am using below code which should render next and previous post thumbnail but it is showing the current post thumbnail in Custom Post Type single page

<?php 

$prevpost = get_previous_post(true);
$prevThumbnail = get_the_post_thumbnail($prevpost->ID, array(80,80) );

next_post_link('%link', '<span>' . $prevThumbnail . '</span>%title'); 

$nextpost = get_next_post(true);
$nextThumbnail = get_the_post_thumbnail($nextpost->ID, array(80,80) );

previous_post_link('%link', '<span>' . $nextThumbnail . '</span>%title');           

?>

How to solve this?

Answer 1

Try without passing the true argument to get_previous_post() function, because that paramters is used to get link of previous post of same category. Possibly you've not registered the category taxonomy while registering that custom post type.
