具有分層url鏈接結構的自定義分類法

Question

我創建了一個名爲instrument_categories的自定義分類法。它工作正常，但我想要的鏈接結構是這樣的：

www.example.com/instruments/term/subterm 

相反，我得到這樣的：

www.example.com/instruments/term/ 
www.example.com/instruments/subterm 

我讀過有關這十幾個崗位，我無法找到我的代碼有任何問題：

add_action('init', 'create_instrument_taxonomies', 0); 

function create_instrument_taxonomies() 
{ 
    // Add new taxonomy, make it hierarchical (like categories) 
    $labels = array(
    'name' => _x('Instrument Categories', 'taxonomy general name'), 
    'singular_name' => _x('Instrument Category', 'taxonomy singular name'), 
    'search_items' => __('Search Instrument Categories'), 
    'popular_items' => __('Popular Instrument Categories'), 
    'all_items' => __('All Instrument Categories'), 
    'parent_item' => __('Parent Instrument Category'), 
    'parent_item_colon' => __('Parent Instrument Category:'), 
    'edit_item' => __('Edit Instrument Category'), 
    'update_item' => __('Update Instrument Category'), 
    'add_new_item' => __('Add New Instrument Category'), 
    'new_item_name' => __('New Instrument Category Name'), 
    ); 
     register_taxonomy('instrument_categories',array('sdp_instrument'), array(
     'hierarchical' => true, 
     'labels' => $labels, 
     'show_ui' => true, 
     'query_var' => true, 
     'rewrite' => array('slug' => 'instruments', 'hierarchal' => true, 'with_front' => true), 
     )); 
} 

我錯過了什麼嗎？我已經確保刷新固定鏈接。爲什麼這不工作？
