I echo a list of categories with the following lines of code. Unfortunatley the foreach($categories as $category) {...
part lists also categories with no posts in it. Any idea how to exclude the empty categories by using the same structure?
<?php $categories = get_categories('exclude=' . implode(',', test_blog_cats()) . ', 1'); ?>
<?php if (!isset($_GET['category'])) {
echo '<li><a class="popular-categories icon-caret-left" href="' . get_permalink() . '">' . __('All Categories', 'test') . '</a></li>';
} else {
echo '<li><a class="popular-categories" href="' . get_permalink() . '">' . __('All Categories', 'test') . '</a></li>';
?>
<?php foreach($categories as $category) { ?>
<li>
<a class="popular-categories<?php if (isset($_GET['category']) && $_GET['category'] == $category->category_nicename) echo ' icon-caret-left bodycolor'; ?>" href="<?php echo get_permalink(); ?>?category=<?php echo $category->category_nicename; ?>"><?php echo $category->name; ?> </a>
</li>
<?php } ?>
