,我認爲這可以幫助:
$cat_id = get_query_var('cat');
if(! empty($cat_id)) {
$category = get_category($cat_id, ARRAY_A);
if(! empty($category)) {
// parent category
if($category['parent'] === '0') {
// get child IDs
$terms = get_term_children($cat_id, 'category');
foreach($terms as $term_id) {
$child_category = get_term($term_id, 'category');
// if you need the category
$category_name = $child_category->name;
/**
* Sample data in your child category object:
*
* object(stdClass)[365]
public 'term_id' => string '14' (length=2)
public 'name' => string 'Child 1' (length=7)
public 'slug' => string 'child-1' (length=7)
public 'term_group' => string '0' (length=1)
public 'term_taxonomy_id' => string '14' (length=2)
public 'taxonomy' => string 'category' (length=8)
public 'description' => string '' (length=0)
public 'parent' => string '12' (length=2)
public 'count' => string '5' (length=1)
public 'object_id' => string '33' (length=2)
*

*/
// do whatever you like with the categories now...
}
} else { // in child category
// do the regular loop here, if (have_posts()) ...
}
}
}

希望可以幫助你:)
