我创建了一个名为 instrument_categories 的自定义分类法。它工作正常，但我希望链接结构是这样的：
www.example.com/instruments/term/subterm
相反，我得到了这个：
www.example.com/instruments/term/
www.example.com/instruments/subterm
我已经阅读了十几篇关于此的帖子，但我的代码没有发现任何问题：
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 ),
));
}
我错过了什么吗？我确保刷新了永久链接。为什么这行不通？
