WordPress 后台很多模块有时并不需要，使用下面的代码可以将它们屏蔽掉。

根据需要，将下面代码添加到当前主题functions.php模板文件中：

function remove_menus() {    global $menu;    $restricted = array(        __('Dashboard'),        __('Posts'),        __('Media'),        __('Links'),        __('Pages'),        __('Appearance'),        __('Tools'),        __('Users'),        __('Settings'),        __('Comments'),        __('Plugins')    );    end ($menu);    while (prev($menu)){        $value = explode(' ',$menu[key($menu)][0]);        if(strpos($value[0], '<') === FALSE) {            if(in_array($value[0] != NULL ? $value[0]:"" , $restricted)){                unset($menu[key($menu)]);            }        }else {        $value2 = explode('<', $value[0]);            if(in_array($value2[0] != NULL ? $value2[0]:"" , $restricted)){                unset($menu[key($menu)]);            }        }    }}if (is_admin()){    // 屏蔽左侧菜单    add_action('admin_menu', 'remove_menus');}

删除子菜单

function remove_submenu() {    // 删除”设置”下面的子菜单”隐私”    remove_submenu_page('options-general.php', 'options-privacy.php');    // 删除”外观”下面的子菜单”编辑”    remove_submenu_page('themes.php', 'theme-editor.php');}if (is_admin()){    //删除子菜单    add_action('admin_init','remove_submenu');}
