我正在尝试创建一个插件，我需要一个自定义帖子和分类法。但它可以在管理端访问，但分类法在前端不起作用。

这是我注册自定义帖子和分类法的方式：

function post_type_questionnaire()
{
    $labels = array(
        \'name\' => _x(\'Questionnaire\', \'post type general name\'),
        \'singular_name\' => _x(\'Questionnaire\', \'post type singular name\'),
        \'add_new\' => _x(\'Add New Question\', \'questionnaire\'),
        \'add_new_item\' => __(\'Add New Questionnaire\')
    );

     $args = array(
        \'labels\' => $labels,
    \'public\' => true,
    \'publicly_queryable\' => true,
    \'show_ui\' => true,
    \'query_var\' => true,
    \'rewrite\' => true,
        \'_builtin\' => false, // It\'s a custom post type, not built in!
    \'capability_type\' => \'post\',
    \'hierarchical\' => false,
    \'menu_position\' => null,
        \'supports\' => array(\'title\',
                            //\'editor\',
                            /*\'excerpt\',
                            \'thumbnail\',
                            \'trackbacks\',
                            \'custom-fields\',
                            \'comments\',
                            \'revisions\',
                            \'author\',
                            \'page-attributes\'*/
    ));

    register_post_type(\'questionnaire\',$args);

}
add_action(\'init\', \'post_type_questionnaire\');



function create_questionnaire_taxanomies(){
    register_taxonomy(\'qcategories\',\'questionnaire\', array(
        \'hierarchical\'=>true,
        \'label\'=>\'Questionnaire Categories\',
        \'rewrite\' => array( \'slug\' => \'questionnaire\' )
    ));
}

add_action(\'init\', \'create_questionnaire_taxanomies\',0);

我正在使用一个短代码在前端显示它。

使用下面的代码显示所有帖子

 $args = array(
    \'post_type\' => \'questionnaire\',
    \'posts_per_page\' => -1,
 );
 $query = new WP_Query($args);
 if ( $query->have_posts() ) { ?>
 <?php while ( $query->have_posts() ) :query->the_post(); ?>

但当我尝试指定一个分类术语时，它不起作用，代码如下：

  $args = array(
    \'post_type\' => \'questionnaire\',
    \'posts_per_page\' => -1,
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'qcategories\',
            \'field\'    => \'slug\',
            \'terms\'     => $atts["name"]
        )
    )
);
$query = new WP_Query($args);
if ( $query->have_posts() ) { ?>
<?php while ( $query->have_posts() ) : $query->the_post(); ?>

当我试图在模板页面中显示帖子数量时，它什么也没有显示：

 $term = get_term( 3, \'qcategories\' );
 echo $term->count;

这不会输出任何东西，所以我相信分类法没有注册，有人能帮我在自定义插件中注册分类法吗。提前感谢！
