对于默认用户类型（管理员、编辑器等），保存时不会从帖子中删除样式标记。对于自定义用户类型，将删除样式标记。

我在函数中应用了过滤器。php文件，以防止剥离，但作为自定义用户类型登录时会忽略该文件。我还直接编辑了wp includes文件夹中的TinyMCE，即使这样也会被忽略。

下面是如何在我的插件中注册用户类型；

function add_roles_on_plugin_activation_tester() {
add_role( \'tester\', \' Tester\', array(
    \'delete_others_pages\' => true,
    \'delete_others_posts\' => true,
    \'delete_pages\' => true,
    \'delete_posts\' => true,
    \'delete_private_pages\' => true,
    \'delete_private_posts\' => true,
    \'delete_published_pages\' => true,
    \'delete_published_posts\' => true,
    \'edit_others_pages\' => true,
    \'edit_others_posts\' => true,
    \'edit_pages\' => true,
    \'edit_posts\' => true,
    \'edit_private_pages\' => true,
    \'edit_private_posts\' => true,
    \'edit_published_pages\' => true,
    \'edit_published_posts\' => true,
    \'manage_categories\' => true,
    \'manage_links\' => true,
    \'moderate_comments\' => false,
    \'publish_pages\' => true,
    \'publish_posts\' => true,
    \'read\' => true,
    \'read_private_pages\' => true,
    \'read_private_posts\' => true,
    \'unfiltered_html \' => true,
    \'upload_files\' => true,
    \'level_1\' => true
) );
}
register_activation_hook( __FILE__, 
\'add_roles_on_plugin_activation_tester\' );
