Question

I’ve followed the documentation here (at the bottom) to create next and back buttons at the bottom of my page.

It seems to work fine until I get to the last page where the link just redirects me back to the first page. Is there a way to say if there isn’t a next page to not show the link? I assumed thats what the if statement was supposed to do!!

<?php
$pagelist = get_pages('sort_column=menu_order&sort_order=asc');
$pages = array();
foreach ($pagelist as $page) {
   $pages[] += $page->ID;
}

$current = array_search(get_the_ID(), $pages);
$prevID = $pages[$current-1];
$nextID = $pages[$current+1];
?>                  

<?php if (!empty($prevID)) { ?>
    <a class="back" href="<?php echo get_permalink($prevID); ?>">BACK</a>
<?php } ?>
<?php if (!empty($nextID)) { ?>
    <a class="next" href="<?php echo get_permalink($nextID); ?>">NEXT</a>
<?php } ?>

p.s Please don’t move my question to the WordPress Stack – that seems to be dying a bit of a death and doesn’t get many responses!

My Pages are setup like this:

Parent page

• Sub page 1
• Sub page 2
• Sub page 3

I’ve created a link on the parent page to goto the first subpage. Then on the subpage template I’ve got the code above. I just want the next link to appear on each page then when it gets to page 3 it shouldn’t show the next link.

If you are saying that this is effectively looping around then $nextID must never be empty, which would be why the link was always displayed.

You could set a $firstID, ie

$firstID = pages[0];

and then check;

if ($firstID != $nextID ) {

   // Display link

}
