我正在尝试创建附加到自定义帖子类型的分类法。CPT的注册情况良好，但分类法没有显示出来。最终会有多种分类法。

我没有看到任何错误（没有致命的WP错误，浏览器控制台中没有任何错误），但WP没有注册分类法。分类法类似乎根本就不存在。我在WP外部进行了检查，以查看是否所有值都存在，并且它们似乎被正确传递。

为什么不注册？感谢您的指导，代码如下。。。

class pm_createTaxonomy
{
protected $textdomain;

public function __construct($textdomain)
{
    $this -> textdomain = $textdomain;

    add_action(\'init\', array($this, \'registerTaxonomy\'));
}

public function makeTaxonomy($taxName, $singularName, $pluralName, $postTypes, $settings=array())
{
    /* Cleanup slugs just in case */
    $this -> taxName = strtolower(str_replace(\' \', \'_\', $taxName));
    $this -> postTypes = $postTypes;

    /* Default labels */
    $default_labels = array(
        \'name\'                       => __($pluralName, $this->textdomain),
        \'singular_name\'              => __($singularName, $this->textdomain),

    );

    $default_args = array(

    $this -> args = array_merge($default_args, $settings);
}

public function registerTaxonomy()
{
    register_taxonomy($this->taxName, $this->postTypes, $this->args);
