前面我们说过在abstract控制器类中初始了应用的配置，系统对此提供了快捷的操作方法。
要使用系统的应用配置，需要在后台控制器中创建setting控制器类，和后台视图setting.php。
创建setting控制器以后，也可直接在 后台-扩展管理中，点击设置按钮进入配置（缺少setting控制器的情况下该按钮为灰色）。
配置好以后就可以使用 $this->setting['var']在控制器中调用，在后台视图中用{$SETTING['var']}来调用。
§ setting控制器
文件：./apps/book/controller/admin/settting.php
class controller_admin_setting extends book_controller_abstract
{
function __construct(& $app)
{
parent::__construct($app);
if (!license('system')) $this->showmessage('请联系 <a href="http://www.cmstop.com/" target="_blank">CmsTop</a> 官方购买授权');
}
public function index()
{
if ($this->is_post())
{
$setting = new setting();
$result = $setting->set_array($this->app->app, $_POST['setting']) ? array('state'=>true,'message'=>'保存成功') : array('state'=>false,'error'=>'保存失败');
echo $this->json->encode($result);
}
else
{
$head = array('title'=>$this->setting['bookname'] .'设置');
$this->view->assign('head', $head);
$this->view->assign('setting', $this->setting);
$this->view->display('setting');
}
}
}
