在addassets（）中从前端获得了一个变量id,保存在本地的uid，然后display出addassets.html页面。但是这个页面中不用uid这个变量，而下一个页面（addassets.html中有一个button跳转到actaddassets.html）actaddassets.html中需要用到uid这个变量。通过上面的方法在actaddassets（）中获得不了uid这个变量。
初次学习，还往大神指点，谢谢！

回复内容：

<code>class AdminAction extends Action {
    private  $uid_t;
    public function addassets(){
        $uid = I('id');
        $this->uid = $uid;
        $this->setuid_t($uid);
        $this->display();
    }

    public function setuid_t($uid){
        $this->uid_t = $uid;
    }

    public function getuid_t(){
        return $this->$uid_t;
    }

    public function actaddassets(){
        $data['uid'] = $this->getuid_t();
        $data['assets_name'] = I('assets_name');

        if ($id=M('device')->add($data)) {
            $this->redirect('index');
        }else{
            echo M('device')->getLastsql();exit;
            $this->redirect('addassets');
        }
    }

做了一些尝试，定义一个static的$uid_t，然后在addassets（）中不输出页面，直接echo self::$uid_t是有值的，但是紧接着在actaddassets（）中再次echo self::$uid_t就没值了。。求教这是为什么。。？谢谢！
