Smarty核心内容：保留变量

{$smarty}保留变量

Request variables

{* display value of page from URL (GET) http://www.domain.com/index.php?page=foo *}
{$smarty.get.page}

{* display the variable "page" from a form (POST) *}
{$smarty.post.page}

{* display the value of the cookie "username" *}
{$smarty.cookies.username}

{* display the server variable "SERVER_NAME" *}
{$smarty.server.SERVER_NAME}

{* display the system environment variable "PATH" *}
{$smarty.env.PATH}

{* display the php session variable "id" *}
{$smarty.session.id}

{* display the variable "username" from merged get/post/cookies/server/env *}
{$smarty.request.username}

{$smarty.now}

{* use the date_format modifier to show current date and time *}
{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}

//访问常量

{$smarty.const}

{$smarty.const._MY_CONST_VAL}

//capture函数的作用是捕获模板输出的数据并将其存储到一个变量里,而不是把它们输出到页面.

//任何在 {capture name="foo"}和{/capture}之间的数据将被存储到变量$foo中，该变量由name属性指定.

//在模板中通过 $smarty.capture.foo 访问该变量.

//如果没有指定 name 属性,函数默认将使用 "default" 作为参数.

{$smarty.capture}

{* we don't want to print a table row unless content is displayed *}{* 该例在捕获到内容后输出一行包含数据的表格，如果没有捕获到就什么也不输出 *}
{capture name=banner}
{include file="get_banner.tpl"}
{/capture}
{if $smarty.capture.banner ne ""}
 <tr>
  <td>
   {$smarty.capture.banner}
  </td>
 </tr>
{/if}

{$smarty.section}, {$smarty.foreach}

{* this example will print out all the values of the $custid array *}
{section name=customer loop=$custid}
 id: {$custid[customer]}<br>
{/section}

OUTPUT:

id: 1000<br>

id: 1001<br>

id: 1002<br>
