我以前从未扮演过角色，所以这是一次有趣的学习经历。我离开这里是因为我花了很多时间研究这个领域，这可能会帮助下一个人。我知道我的问题是关于分类法的，但我对这个问题感到困惑，所以我想从CPT级别进行测试。正确的挂钩是admin_init 然而，它仍在从administrator 和editor 我不想那样。

在我遇到答案之前”Possible to hide Custom Post Type UI/Menu from specific User Roles?“但当我使用以下函数时：

// hide from Contributors
function no_see_from_contributors() {
    if ( current_user_can( \'contributor\' ) ) :
        remove_menu_page( \'edit.php\' ); // Posts
        remove_menu_page( \'tools.php\' ); // Tools
        remove_menu_page( \'edit-comments.php\' ); // Comments
    endif;
}
add_action( \'admin_menu\', \'no_see_from_contributors\' );

之后的进一步研究导致了“Restrict custom post type to only site administrator role“和”Remove Custom Post Type menu for non-administrator users“这本书读得很好。要了解有关功能的更多信息，您可以访问Codex: register post type 并向下滚动至capability_type.

您可以参考法典Administrator 和Editor 在阵列中使用哪些角色。

最终分类法：

function something_taxonomy() {
    $labels = array(
        \'name\'                       => _x( \'Taxonomies\', \'Taxonomy General Name\', \'theme\' ),

您想使用admin_init 挂钩：

add_action( \'admin_init\' , \'taxonomy_for_admin_and_editor_only\' );
