Hi, I have a tag snipet with the following code :slight_smile: <?php $tags = $page->children()->visible()->pluck('tags', ',', true); if($tags): ?> <div class="filter"> <hr> <h3>Par Thème</h3> <ul> <li class="inbl"><a href="<?php echo $page->url() ?>"><button class= "btn plain">←…

Where did you define $tagged. Maybe I’m foolish, maybe I’m blind, but I can’t see it anywhere? You should have something like: <?php $tagged = kirby()->request()->params()->tag(); or <?php $tagged = param('tag'); somewhere…

Actually in the controller I have the following code where tagged is defined as $tagged = urldecode($data['tag']); <?php return function ($site, $pages, $page, $data) { $children = $page->children()->visible(); if (isset($data['tag'])) { $tagged = urldecode($data['ta…

Well, the problem with your code is that $tagged is undefined if $data['tag'] does not exist. Where does $data come from, from a route? In any case, you should set $tagged to empty if the condition is not met.

I add the following code: <a href="<?php echo $page->url() . '/' . $tag ?>"> <button <?php if(!empty($tagged)): e($tag == $tagged, 'class="btn special"') ?> <?php endif ?>> <?php echo $tag ?> </button></a> It seems to work now. Thank you
