[Support request] Adding next previous buttons for (sub)pages not working

[Jack]

I have this code that used to work in the older version of the website, but I’m having difficulty to get it to work in GP.

It used to be inside page.php in the old theme, but I now added it using a hook element, execute PHP checked and the hook location I varied just to be sure I wasn’t making a stupid mistake (after header, before content, before main content etc.), and the display rule set to alle pages or entire site, nothing works. Adding a simple echo ‘hello’ works, so that is okay. The ID’s of the pages inside the code have not changed.

It should be visible on a subpage like this one: https://www.ullstorp.se/activities-available-here-or-near-ullstorp/swim-and-sunbathe-here-at-ullstorp/?lang=en

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

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

<?php
if ( 5133 == $post->post_parent || 5135 == $post->post_parent || 6250 == $post->post_parent || 6252 == $post->post_parent || 6251 == $post->post_parent) {
?>

<div class="navigation">
<?php if (!empty($prevID)) { ?>

<div class="previous">
<a href="<?php echo get_permalink($prevID); ?>" title="<?php echo get_the_title($prevID); ?>"><?php echo get_the_title($prevID); ?></a>
</div>

<?php } if (!empty($nextID)) { ?>

<div class="next">
<a href="<?php echo get_permalink($nextID); ?>" title="<?php echo get_the_title($nextID); ?>"><?php echo get_the_title($nextID); ?></a>
</div>

<?php } ?>
</div>

<?php } ?>

Hi there,

no errors showing on the front end when you add the code ? ?

[Jack]

No, nothing.

[David]

As its hooked outside of the loop, try adding:

global $post;

at the top of the code.

[Jack]

No luck I’m afraid. I also chose Before and After Entry Title and more.

When I uncheck ‘Execute PHP’, the content is displayed in the website at the right place, otherwise the code isn’t even visible in the source.

I just deactivated the Kadence Blocks plugin, saw that the links are on the website, then reactivated that plugin again and the links are still there! Seems to be working now, although I have no idea what deactivating and reactivating did.

[David]

Oh wow, that is very peculiar – i wonder what Kadence is doing that would mess with that.
But i am glad to hear you got it working !!
