我试图用此代码重命名我的post标记，但出现以下错误：

注意：未定义的属性：stdClass:：/var/www/new/wp admin/includes/class wp posts列表中的$no\\u terms。php在线1107

我的代码：

<?php  

function rename_texonomy_tag()
{
    global $wp_taxonomies;
    $wp_taxonomies[\'post_tag\']->labels = (object)array(
        \'name\' => \'Groups\',
        \'menu_name\' => \'Groups\',
        \'singular_name\' => \'Group\',
        \'search_items\' => \'Search Groups\',
        \'popular_items\' => \'Popular Groups\',
        \'all_items\' => \'All Groups\',
        \'parent_item\' => null, // Tags aren\'t hierarchical
        \'parent_item_colon\' => null,
        \'edit_item\' => \'Edit Groups\',
        \'update_item\' => \'Update Groups\',
        \'add_new_item\' => \'Add new Groups\',
        \'new_item_name\' => \'New Groups Name\',
        \'separate_items_with_commas\' => \'Separata Groups with commas\',
        \'add_or_remove_items\' => \'Add or remove Groups\',
        \'choose_from_most_used\' => \'Choose from the most used Groups\',
    );

    $wp_taxonomies[\'post_tag\']->label = \'Groups\';
}

?>
