Under most circumstances this would be an easy answer, but I have a slightly trickier segment I am working with.

The following code displays the category names if they are selected in the entry:

<div class="project-brief open-close">
    <h3>Results Type</h3>
        <div class="project-brief">
            <ul class="brief-list">
                <?php  $parents= array(); ?>
                {categories show_group="5"}
                <?php $parent_id = '{parent_id}'; if(!$parent_id) {$parents ['{category_id}'] = '{category_name}';} ?>

                <?php foreach ($parents as $key => $parent) { ?>
                <li><a href="/projects?category=<?php echo $key; ?>"><?php echo $parent; ?></a>
                    <ul class="brief-list-childs">
                        {categories show_group="5"}
                        {if parent_id == <?php echo $key; ?>}<li><a href="/projects?category={category_id}">{category_name}</a></li>{/if}
                <?php } ?>


However, the client wants to hide the entire section if none are selected in the entry.

I want to wrap the entire div in a conditional that checks to see if any of the categories are checked and display it only if it is not empty.

I would say it like this, but I can't seem to get the conditional right. Any guidance will be appreciated.

{If category count > 1}
   ... display the content

Not sure if this still works but might be worth a try:

{if "{categories}{category_name}{/categories}" != ""}

  • Hi Nathan, this worked with one caveat. I needed to add this to the categories tag: show_group="5". Thanks for the timely help!
