ThinkPHP数据模板显示——系统变量、常量、配置文件

二、系统变量输出

普通的模板变量需要首先赋值后才能在模板中输出,但是系统变量则不需要,可以直接在模板中输出,系统变量的输出通常以 {$Think打头,eg:

{$Think.server.script_name}   //输出$_SERVER['SCRIPT_NAME']变量{$Think.session.user_id}      //输出$_SESSION['user_id']变量{$Think.get.pageNumber}       //输出$_GET['pageNumber']变量{$Think.cookie.name}          //输出$_COOKIE['name']变量
Copy after login

?支持输出 $_SERVER, $_ENV, $_POST, $_GET, $_REQUEST, $_SESSIOIN 和$_COOKIE变量

三、常量输出

1.系统常量

输出常量:{$Think.const.MODULE_NAME}或者	:{$Think.MODULE_NAME}
Copy after login

?2.在控制器中自定义常量并输出

控制器:	const PAI = 3.14;  		$this->assign("pai",self::PAI);		$this->display();模板 : 	{$pai}
Copy after login

四、配置输出

首先,在配置文件中有定义,在模板文件中才可以直接调用输出

输出配置参数: {$Think.config.db_charset}		      {$Think.config.url_model}
Copy after login

??五、语言输出

输出语言变量: {$Think.lang.page_error}		      {$Think.lang.var_error}
Copy after login
