我假设您的意思是限制访问权限，以编辑管理界面中的侧栏，而不是删除它的主题。

如果不深入了解小部件/侧栏框架在幕后的工作方式，那么最好的选择就是$wp_registered_sidebars 全球的然而，关键是当时间太早和wp管理/小部件时。php模板将看到缺少的侧栏，并将其移到非活动侧栏“侧栏”。太晚了，而且，你没有效果。

add_action(\'widgets_admin_page\', \'sidebar_capabilities\');

/**
 * Keep in mind that you can certainly create custom
 * capabilities for your sidebars. You could create a loop
 * that generates new capabilities for each sidebar and assigns them
 * to admin. You could then manage those capabilities for other 
 * users with the Members plugin by Justin Tadlock
 */
function sidebar_capabilities(){
    global $wp_registered_sidebars;

    //Remove the comment lines to see the global variable structure.
    //print_r($wp_registered_sidebars); 

    //Use whatever capabilities you want. 
    //To test as admin, just put junk text for the cap.
    if(is_admin() && !current_user_can(\'edit_plugins\')){

        //This sidebar name is from the twenty-ten theme.
        unset($wp_registered_sidebars[\'primary-widget-area\']);
    }
}
