Smarty模板引擎的使用

Smarty模板引擎的使用

Smarty是PHP中一个基于MVC模式的模板引擎。

Download: http://www.smarty.net/download

 

特点

1、  最快速度的程序开发模板

2、  自定义模板的界定符

3、  可以使用条件判断语句if/elseif/else/endif

4、  内建缓存支持

5、  可以自定义插件.

 

Smarty其实很简单，目前的3.1.14版本中的一个Demo的目录如下：

 

只有简单的几个文件夹。

 

Index.php

<?php

 /**

 * Example Application



 * @package Example-application

 */

 

//载入Smarty的核心类库文件

require('libs/Smarty.class.php');

//实例化一个Smarty

$smarty = new Smarty;







//$smarty->force_compile = true;

//调试模式，会弹出调试框，查看变量值

$smarty->debugging = true;

 //缓存模式

$smarty->caching = true;

 //缓存时间 

$smarty->cache_lifetime = 120;



//定义一个数据的MAP，将数据发送到模板中去

$smarty->assign("Name","Fred Irving Johnathan Bradley Peppergill",true);

$smarty->assign("FirstName",array("John","Mary","James","Henry"));

$smarty->assign("LastName",array("Doe","Smith","Johnson","Case"));

$smarty->assign("Class",array(array("A","B","C","D"), array("E", "F", "G", "H"),

	  array("I", "J", "K", "L"), array("M", "N", "O", "P")));



$smarty->assign("contacts", array(array("phone" => "1", "fax" => "2", "cell" => "3"),

	  array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234")));



$smarty->assign("option_values", array("NY","NE","KS","IA","OK","TX"));

$smarty->assign("option_output", array("New York","Nebraska","Kansas","Iowa","Oklahoma","Texas"));

$smarty->assign("option_selected", "NE");



//显示一个模板

$smarty->display('index.tpl');

?>

 

 

使用的都是默认的各个目录文件夹，显示如资源列表图。

当然，还有很多的参数设置，可以参考Smarty.class.php文件，不做详细介绍了。

index.tpl 中的解析

 

{*这样的是注释*}

{* {} 是界定符 *}



{*载入 配置文件 *}

{config_load file="test.conf" section="setup"}



{* 载入一个文件，并传入一个变量 title = foo *}

{include file="header.tpl" title=foo}



<PRE>



{* ##是从config 文件读取的配置数据 *}

{if #bold#}<b>{/if}

{* 

  ‘|’ 是针对变量的修饰符，

  capitalize   首字母大写

  upper		   全部大写

  lower        全部小写

  nl2br        将换行符换位<br/>

  date_format:"%Y-%M-%D"   格式化时间

  replace："value1":"value2" 替换，使用value2替换value1

  dafault      默认值

  cat:"characters"    追加字符

  .....

*}

Title: {#title#|capitalize}

{if #bold#}</b>{/if}



The current date and time is {$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}



The value of global assigned variable $SCRIPT_NAME is {$SCRIPT_NAME}



{*

{$smarty.server.SERVER_NAME}   服务器 地址

*}

Example of accessing server environment variable SERVER_NAME: {$smarty.server.SERVER_NAME}



The value of {ldelim}$Name{rdelim} is <b>{$Name}</b>

{*

{ldelim}   左界定符

{rdelim}   右界定符

*}

variable modifier example of {ldelim}$Name|upper{rdelim}



<b>{$Name|upper}</b>





An example of a section loop:



{section name=outer 

loop=$FirstName}

{* 没两次 交替 一次*}

{if $smarty.section.outer.index is odd by 2}

	{$smarty.section.outer.rownum} . {$FirstName[outer]} {$LastName[outer]}

{else}

	{$smarty.section.outer.rownum} * {$FirstName[outer]} {$LastName[outer]}

{/if}

{sectionelse}

	none

{/section}



An example of section looped key values:

{* 类似 泛型的枚举  循环*}

{section name=sec1 loop=$contacts}

	phone: {$contacts[sec1].phone}<br>

	fax: {$contacts[sec1].fax}<br>

	cell: {$contacts[sec1].cell}<br>

{/section}

<p>



testing strip tags

{strip}

<table border=0>

	<tr>

		<td>

			<A HREF="{$SCRIPT_NAME}">

			<font color="red">This is a  test     </font>

			</A>

		</td>

	</tr>

</table>

{/strip}



</PRE>



This is an example of the html_select_date function:



{* 时间选择器*}

<form>

{html_select_date start_year=1998 end_year=2010}

</form>



This is an example of the html_select_time function:



<form>

{html_select_time use_24_hours=false}

</form>



This is an example of the html_options function:



{* option 枚举*}

<form>

<select name=states>

{html_options values=$option_values selected=$option_selected output=$option_output}

</select>

</form>



{include file="footer.tpl"}

 

在服务器上显示的  index.php就显示如下了
