是的，您可以使用get_categories() 使用\'child_of\' 属性例如，ID为17的类别的所有子类别：
$args = array(\'child_of\' => 17);
$categories = get_categories( $args );
foreach($categories as $category) {
echo \'<p>Category: <a href="\' . get_category_link( $category->term_id ) . \'" title="\' . sprintf( __( "View all posts in %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a> </p> \';
echo \'<p> Description:\'. $category->description . \'</p>\';
echo \'<p> Post Count: \'. $category->count . \'</p>\';
}
如果要仅显示直接子类的类别（即仅限子类），可以使用\'parent\' 属性
$args = array(\'parent\' => 17);
$categories = get_categories( $args );
foreach($categories as $category) {
echo \'<p>Category: <a href="\' . get_category_link( $category->term_id ) . \'" title="\' . sprintf( __( "View all posts in %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a> </p> \';
echo \'<p> Description:\'. $category->description . \'</p>\';
echo \'<p> Post Count: \'. $category->count . \'</p>\';
}

对于自定义帖子类型“；“类别”；使用get_terms().
（更改@Bainternet的答案）
$categories = get_terms( array(
\'taxonomy\' => \'product_cat\',
\'hide_empty\' => false,
\'parent\' => 17 // or
//\'child_of\' => 17 // to target not only direct children
) );
foreach($categories as $category) {
echo \'<p>Category: <a href="\' . get_category_link( $category->term_id ) . \'" title="\' . sprintf( __( "View all posts in %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a> </p> \';
echo \'<p> Description:\'. $category->description . \'</p>\';
echo \'<p> Post Count: \'. $category->count . \'</p>\';
}
结束
