I have a wordpress parent page with child and its grand child pages in following structure.
-Parent page
- Grandchild 1 (page id = 5)
- Grandchild 2 (page id = 9)
- Grandchild 3 (page id = 11)
- Grandchild 4 (page id = 15)
- Grandchild 5 (page id = 22)
I am trying to do a custom “The Next and Previous Pages” function with only grandchild pages as pages. so i have an array with page ID’s as follows
$pages = array(‘1’=>’5’, ‘2’=>’9′, ‘3’=>’11’, ‘4’=>’15’, ‘5’=>’22’);
I tried to make use of steps mentioned in https://codex.wordpress.org/Next_and_Previous_Links#The_Next_and_Previous_Pages, but ‘Next Page’ link is not appearing in Grandchild 3′ and ‘Previous page’ link in ‘Grandchild 4’ page, is there is any way to make this work?
Thanks
My code
<?php
$pages = array('1'=>'5', '2'=>'9', '3'=>'11', '4'=>'15', '5'=>'22');
$current = array_search(get_the_ID(), $pages);
$prevID = $pages[$current-1];
$nextID = $pages[$current+1];
?>
<div class="navigation">
<?php if (!empty($prevID)) { ?>
<div class="alignleft">
<a href="<?php echo get_permalink($prevID); ?>"
title="<?php echo get_the_title($prevID); ?>">Previous</a>
</div>
<?php }
if (!empty($nextID)) { ?>
<div class="alignright">
<a href="<?php echo get_permalink($nextID); ?>"
title="<?php echo get_the_title($nextID); ?>">Next</a>
</div>
<?php } ?>
</div><!-- .navigation -->
