我正在使用wordpress自定义贴子和register\\u分类，下面是我的代码。

function epg_works_register() {
    $labels = array(
        \'name\' => __(\'Works\'),
        \'singular_name\' => __(\'Works\'),
        \'add_new\' => __(\'Add Works Item\'),
        \'add_new_item\' => __(\'Add New Works Item\'),
        \'edit_item\' => __(\'Edit Works Item\'),
        \'new_item\' => __(\'New Works Item\'),
        \'view_item\' => __(\'View Works Item\'),
        \'search_items\' => __(\'Search Works Item\'),
        \'not_found\' => __(\'No Works Items found\'),
        \'not_found_in_trash\' => __(\'No Works Items found in Trash\'),
        \'parent_item_colon\' => \'\',
        \'menu_name\' => __(\'Works\')
    );
    // Set other options for Custom Post Type

    $args = array(
        \'labels\'              => $labels,
        // Features this CPT supports in Post Editor
        \'supports\'            => array( \'title\', \'editor\'),

        /* A hierarchical CPT is like Pages and can have
        * Parent and child items. A non-hierarchical CPT
        * is like Posts.
        */  
        \'hierarchical\'        => true,
        \'public\' => true,
        \'show_ui\'             => true,
        \'show_in_menu\'        => true,
        \'show_in_nav_menus\'   => true,
        \'menu_position\'       => 5,
        \'can_export\'          => true,
        \'has_archive\'         => true,
        \'exclude_from_search\' => true,
        \'publicly_queryable\'  => true,
        \'capability_type\'     => \'post\',
    );

    // Registering your Custom Post Type
    register_post_type( \'works\', $args );

    register_taxonomy(\'works_category\', \'works\', array(\'hierarchical\' => true, \'label\' => \'Works Category\', \'query_var\' => true, \'rewrite\' => array(\'slug\' => \'works-categorys\')));

    flush_rewrite_rules();
}
add_action( \'init\', \'epg_works_register\');

如果我将register\\u taxonomy（\'works\\u category\'更改为register\\u taxonomy（\'something\'），则会显示http://localhost/wp-admin/nav-menus.php

但是如果使用register\\u分类法（“works\\u category”），那么我在那里看不到任何东西http://localhost/wp-admin/nav-menus.php.

怎么了？

谢谢

 register_taxonomy(
      \'works_category\', 
      \'works\', 
           array(
                \'hierarchical\' => true, 
                \'label\' => \'Works Category\', 
                \'query_var\' => \'works_category\', 
                \'rewrite\' => array(\'slug\' => \'works-categorys\')
           )
 );

register_taxonomy(\'mycat\', \'mycustomtype\',
 array(
 //...,
 \'capabilities\' => array(
  \'manage_terms\' => \'manage_categories\',
  \'edit_terms\' => \'manage_categories\',
  \'delete_terms\' => \'manage_categories\',
  \'assign_terms\' => \'edit_posts\'
  )
 )
);
