显示当前文章分类和父分类的链接

当需要显示文章的父分类和当前分类链接时，我们可以使用这段代码：

$categories = get_the_category();
echo '<ul>';
echo '<li> Parent Category: ';
foreach( $categories as $category ){
if($category->parent != 0){
$parent_category = get_term( $category->parent );
echo '<a href="' . esc_url( get_category_link($parent_category->term_id)) . '">' . esc_html($parent_category->name) . ' </a>';
break;
}
}
echo '</li>';
echo '<li>Subcategory: ';
foreach( $categories as $category ){
if($category->parent != 0){
echo '<a href="' . esc_url( get_category_link($category->term_id)) . '">' . esc_html($category->name) . ' </a>';
}
}
echo '</li></ul>';
