我正在使用wordpress 4.9.7，希望为我的帖子类型添加自定义分类法。

我已将代码打包在mu-plugins 文件夹，以便wordpress需要它。查找以下我的代码：

<?php

function computerBoxBuilder_post_types()
{

    // Computer Hardware Post Type
    register_post_type(\'Computer-Hardware\', array(
        \'supports\' => array(\'title\', \'editor\', \'thumbnail\', \'custom-fields\'),
        \'public\' => true,
        // \'exclude_from_search\' => true,
        \'publicly_queryable\' => true,
        \'show_ui\' => true,
        \'labels\' => array(
            \'name\' => \'Computer-Hardware\',
            \'add_new_item\' => \'Add New Computer-Hardware\',
            \'edit_item\' => \'Edit Computer-Hardware\',
            \'all_items\' => \'All Computer-Hardware\',
            \'singular_name\' => \'Computer-Hardware\',
        ),
        \'menu_icon\' => \'dashicons-dashboard\',
        \'taxonomies\' => array( \'category\' ),
    ));
    
}

// Register Custom Taxonomy
function custom_taxonomy() {

    $labels = array(
