Smarty comes with several built-in functions. Built-in functions are integral to the template language. You cannot create custom functions with the same names, nor can you modify built-in functions.

Smarty自帶一些內(nèi)建函數(shù).
內(nèi)建函數(shù)是模板語言的一部分.
用戶不能創(chuàng)建名稱和內(nèi)建函數(shù)一樣的自定義函數(shù),也不能修改內(nèi)建函數(shù).

capture

Attribute Name Type Required Default Description
name string no default The name of the captured block
assign string No n/a The variable name where to assign the captured output to

屬性 類型 是否必須 缺省值 描述
name string no default 數(shù)據(jù)采集區(qū)域名稱
assign string No n/a 數(shù)據(jù)采集區(qū)域在哪分配給變量name[待考]

capture is used to collect the output of the template into a variable instead of displaying it. Any content between {capture name="foo"} and {/capture} is collected into the variable specified in the name attribute. The captured content can be used in the template from the special variable $smarty.capture.foo where foo is the value passed in the name attribute. If you do not supply a name attribute, then "default" will be used. All {capture} commands must be paired with {/capture}. You can nest capture commands.

capture函數(shù)的作用是捕獲模板輸出的數(shù)據(jù)并將其存儲到一個變量里,而不是把它們輸出到頁面.
任何在 {capture name="foo"}和{/capture}之間的數(shù)據(jù)將被存儲到變量$foo中，該變量由name屬性指定.
在模板中通過 $smarty.capture.foo 訪問該變量.
如果沒有指定 name 屬性,函數(shù)默認(rèn)將使用 "default" 作為參數(shù).
{capture}必須成對出現(xiàn)，即以{/capture}作為結(jié)尾,該函數(shù)不能嵌套使用.

Technical Note: Smarty 1.4.0 - 1.4.4 placed the captured content into the variable named $return. As of 1.4.5, this behavior was changed to use the name attribute, so update your templates accordingly.

技術(shù)提示:
Smarty 1.4.0 - 1.4.4 版把捕獲到的內(nèi)容存儲于 $return 變量里.
在 1.4.5 版以后就將該數(shù)據(jù)保存到了由 name 屬性指定的變量里.請升級你的模板.

Caution

Be careful when capturing {insert} output. If you have caching turned on and you have {insert} commands that you expect to run within cached content, do not capture this content.


警告

當(dāng)希望捕獲包含 {insert} 命令的數(shù)據(jù)時要特別注意. 如果打開了緩存并希望將 {insert} 命令輸出到緩存中，不要捕獲該區(qū)域的數(shù)據(jù).

Example 7-1. capturing template content
例 7-1.捕獲模板內(nèi)容 

{* we don't want to print a table row unless content is displayed *}
{* 該例在捕獲到內(nèi)容后輸出一行包含數(shù)據(jù)的表格，如果沒有捕獲到就什么也不輸出 *}
{capture name=banner}
{include file="get_banner.tpl"}
{/capture}
{if $smarty.capture.banner ne ""}
	<tr>
		<td>
			{$smarty.capture.banner}
		</td>
	</tr>
{/if}
