我一直在尝试各种方法。基本上，我一直在尝试这样做，以便我的一个插件在插件激活期间只填充一次分类法的术语。术语填充是通过wp\\u insert\\u terms函数在函数中完成的。直接在register\\u activation\\u钩子内调用函数似乎不起作用，使用register\\u activation\\u钩子钩住init钩子也不起作用。有人有什么想法吗？

这是我的代码版本

//version 1
class vsetup {
     function __construct() {
          register_activation_hook(__FILE__,array($this,\'activate\'));
          $this->create_taxonomies();
     } 
     function activate() {
          wp_insert_term(\'Action\',\'genre\');
          wp_insert_term(\'Adventure\',\'genre\');
     }
     function create_taxonomies() {
           $genre_args = array( 
            \'hierarchical\' => true,  
                \'labels\' => array(
            \'name\'=> _x(\'Genres\', \'taxonomy general name\' ),
            \'singular_name\' => _x(\'Genre\', \'taxonomy singular name\'),
            \'search_items\' => __(\'Search Genres\'),

            \'rewrite\' => array(\'slug\' =>\'genre\')
