a-ok Posted March 4, 2017 Share Posted March 4, 2017 Hi all. I'm using a simple parent/children page setup to act like categories (Categories > category 1, category 2, category 3 etc). When adding a new page, using the PageField, the user can multi-select which 'categories' this page relates to. Simple. On the front end I am looping through the categories: <?php $categories = $pages->find('parent=/categories/, sort=name'); ?> <?php foreach ($categories as $category) : ?> <li><a href="#" data-name="<?php echo $category->name; ?>"><?php echo $category->title; ?></a></li> <?php endforeach; ?> This is then going to act as a filter... however... I'm wondering if it's possible to only show the categories that are currently in use... rather than showing them all? What do you think? Link to comment Share on other sites More sharing options...
Sergio Posted March 4, 2017 Share Posted March 4, 2017 You can have something like this, considering your page field is called "categories". Not tested! <?php $categories = $pages->find('parent=/categories/, sort=name'); ?> <?php foreach ($categories as $category) : if ($pages->count("categories=$category")) > 0 : ?> <li><a href="#" data-name="<?php echo $category->name; ?>"><?php echo $category->title; ?></a></li> <?php endif; endforeach; ?> 2 Link to comment Share on other sites More sharing options...
