Introduction to the usage of thinkphp's $this (with code)

本篇文章给大家带来的内容是关于thinkphp的$this的用法介绍（附代码），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

常用方法：

$this -> user[''id] 在user表中查询user_info ，user_info的其它字段值可以去对应的主表中查询各种值。

在HomeController.class.php中建立几个方法（获取渠道消息，获取用户消息，获取推广信息等） 并在一开始就调用，在其它php中public function _initialize(){
        parent::_initialize();} 引入这些常用的方法产生的array(用户、渠道、推广等)，$this -> user[''id] 在user表中查询user_info ，user_info的其它字段值可以去对应的主表中查询各种值。

 public function _initialize(){
		parent::_initialize();
		if(PHP_SAPI != 'cli' && !IS_MOBILE){
			// 非手机访问处理逻辑
		}

		// 获取渠道信息
		$this -> _get_channel();

		// 有推广参数则记录推广信息
		$this -> _record_spread();

		// 获取代理信息
		$this -> _get_agent();

		// 开发调试时快捷模拟登陆任何用户
		if(APP_DEBUG && $_GET['debug_user_id']){
			session('user', M('user') -> find($_GET['debug_user_id']));
		}

		if(!$this -> user && session('?user')){
			$this -> user = M('user') -> find(session('user.id'));
		}

		// cookie 自动登录
		if(!$this -> user && cookie('user') && 0){
			$cookie = cookie('user');
			$sign = xmd5($cookie['user_id'].$cookie['timestamp']);
			if($sign != $cookie['sign']){
				cookie('user', null);
				$cookie = null;
			}

			if($cookie && $cookie['user_id']){
				$this -> user = M('user') -> find($cookie['user_id']);
			}
		}

		// 如果是微信则尝试自动登录
		if(!$this -> user && !session('?no_mp') && IS_WECHAT && CONTROLLER_NAME !='Pay'){
			$this -> user = $this -> _auto_login();
		}
