我刚刚编写了这个快速插件，它似乎可以工作。如果有更好的方法，请告诉我。

<?php

/*
Plugin Name: Theme Switch if Admin
Description: Display different theme to user if logged in as admin
Author: Kyle Barber
*/
    add_filter(\'template\', \'change_theme\');
    add_filter(\'option_template\', \'change_theme\');
    add_filter(\'option_stylesheet\', \'change_theme\');
    function change_theme($theme) {
        if ( current_user_can(\'manage_options\') ) {
            $theme = \'twentyeleven\';
        }

        return $theme;
    }
