4. smarty 系统变量

{* 显示URL中的page值($_GET)http://www.example.com/index.php?page=foo *}
{$smarty.get.page}
{* 显示来自一个表单的"page"变量($_POST['page'])*}
{$smarty.post.page}
{* 显示COOKIE变量"username"的值($_COOKIE['username'])*}
{$smarty.cookies.username}
{* 显示服务器变量"SERVER_NAME"($_SERVER['SERVER_NAME'])*}

{$smarty.request.username}

{$smarty.now}变量用于访问当前时间戳.
可以用 date_format调节器格式化输出. 例如{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}

{$smarty.const}
你可以直接访问PHP常量. 例如{$smarty.const._MY_CONST_VAL}

{$smarty.capture}
可以通过{capture}..{/capture}结构 截取的输出可以使用{$smarty} 变量访问.

{$smarty.config}
{$smarty}变量 可以访问已经加载的config变量.

例如 {$smarty.config.foo}就可以表示 {#foo#}.
