{* we don't want to print a div tag unless content is displayed *}
{capture name="banner"}
{capture "banner"} {* short-hand *}
  {include file="get_banner.tpl"}
{/capture}

{if $smarty.capture.banner ne ""}
<div id="banner">{$smarty.capture.banner}</div>
{/if}

下面是capture函數的演示

{capture name=some_content assign=popText}
{capture some_content assign=popText} {* short-hand *}
The server is {$my_server_name|upper} at {$my_server_addr}<br>
Your ip is {$my_ip}.
{/capture}
<a href="#">{$popText}</a>

下面例子演示了如何多次捕獲內容，形成數組。

{capture append="foo"}hello{/capture}I say just {capture append="foo"}world{/capture}
{foreach $foo as $text}{$text} {/foreach}

輸出：

I say just hello world
