我想知道是否有办法防止在分类法中添加新类别，本质上是“锁定”分类法。
我正在通过编程注册一个分类法，并通过函数用术语填充它。php和希望它，所以你不能再添加到它。
实现的愿景
这是我的解决方案的最终结果，它工作得很好！感谢所有帮助过我的人。在你面前到处投票！

如果要独立地将术语添加到分类法中，并且要隐藏UI，为什么不简单地使用register_taxonomy\'s支持的参数。
capabilities
（数组）（可选）此分类法的功能数组。
默认值：无
“manage\\u terms”-“manage\\u categories”-“edit\\u terms”-“manage\\u categories”-“delete\\u terms”-“manage\\u categories”-“assign\\u terms”-“edit\\u posts”
show_ui
（布尔）（可选）是否生成用于管理此分类的默认UI。
默认值：如果未设置，则默认为公共参数的值
将这些功能设置为一些不存在的功能，您将从本质上阻止用户修改、创建或删除它们。如果您需要能够以传统方式（即通过帖子编辑器）将它们分配给帖子，只需使用assign_terms 价值
Example:
$args = array(
....
\'capabilities\' => array(
\'manage_terms\' => \'foobar\',
\'edit_terms\' => \'foobar\',
\'delete_terms\' => \'foobar\',
\'assign_terms\' => \'foobar\' // <-- change this one to a desired cap if you need to be able to assign them(you could use manage_options for admins only)
),
);
设置
show_ui 如果设置为false，则将阻止显示分类法的任何菜单项。
希望这有助于。。。
