如何检查类别是否为父类别

Question

我怎么可能这样做？另外我如何显示其子类别？

Answer 1

检查

<?php $this_category = get_category($cat); ?>
<!-- If category is parent, list it -->
<?php if ($this_category->category_parent == 0) { ?>

<?php } else { ?>
<!-- If category is not parent, list parent category -->
<?php $parent_category = get_category($this_category->category_parent); ?>


<?php } ?>
