1.登入函式中存登入時間：

session('logintime',time());

class CheckAction extends Action {
        public function __construct() {
            parent::__construct();
            $this->checkAdminSession();
        }
        public function checkAdminSession() {
           // echo "happy";
            //設定超時為10分
            $nowtime = time();
            $s_time = session('logintime');
            if (($nowtime - $s_time) > 1800) {
                session('logintime',null);
                $this->error('當前使用者未登入或登入超時，請重新登入', U('Admin/Index/index'));
            } else {
                session('logintime',$nowtime);
            }
        }
}
 

例：

lass AnnouceAction extends CheckAction
{
   
    public function lists(){
		$username = session('agentName');
		//判斷是否有輸入密碼；
		if(empty($username)){
		//如果為空跳回登入頁；
			$this->redirect('QiXunAgent/Index/index');
		}
		$age=M('agentuser')->where(array('account'=>$username))->find();
		$m=M('announceforman');			 		
	 //載入分頁類
		import('ORG.Util.Page');
	//計算記錄總數
		$condition['managerID'] = 0;
		$condition['agentID'] = $age['id'];
		$count = $m->where($condition)->count();
	//例項化分頁類
		$page = new Page($count,8);
	//設定主題
		$page->setConfig('header','');
		$page->setConfig('theme',"%totalRow% %header% 當前第 %nowPage% 頁  共 %totalPage% 頁 %upPage% %downPage% %first% %prePage% <span style='letter-spacing:5px'>%linkPage%</span> %nextPage% %end%");

	//設定超連結
		$this->show = $page->show();
			
		$data = $m->where($condition)->order('datetime desc')->limit($page->firstRow.",".$page->listRows)->select();	
		$this->assign('data',$data);
		$this->display();
	}
}
