When we want to configure links between a blog’s next and previous pages, there is absolutely no function to return ONLY the URLs of the next and previous pages. To save the time below simple thing will help.
To return the URL of the previous page, use the following php code:
$prev = get_permalink(get_adjacent_post(false,'',false));
To return the URL of the next page, use the following php code:
$next = get_permalink(get_adjacent_post(false,'',true));
To use them, simply echo the variables $prev and $next where you need them.
<a href="<?php echo $prev; ?>">Previous Post</a> <a href="<?php echo $next; ?>">Next Post</a>
If there isn’t a previous or next post follow below:
Since our functions will automatically return either the adjacent post’s URL if there is one or the current post’s own URL if you’re on the first or last post. Use the following code to make it conditional whether to display the previous or next post link:
<?php $prev = get_permalink(get_adjacent_post(false,'',false)); if
($prev != get_permalink()) { ?><a href="
<?php echo $prev; ?>">Previous Post Only Displaying If Available</a><?php } ?>
