[PHP] - Smarty母版使用方法(类似ASP.NET母版)

来源：http://www.flyy.info/480.html

用过asp.net的母版页的人应该感觉这个东西还是有值得php借鉴的地方。
新出来的 smarty 3  引入了 Template Inheritance 概念，能和asp.net 的母版页实现同样的功能。

Template inheritance example

layout.tpl (parent)

  
    

   
     <
   
     html
   
     >
   
     

   
     <
   
     head
   
     >
   
     
 
   
     <
   
     title
   
     >
   
     {block name=title}Default Page Title{/block}
   
     </
   
     title
   
     >
   
     
 {block name=head}{/block}

   
     </
   
     head
   
     >
   
     

   
     <
   
     body
   
     >
   
     
{block name=body}{/block}

   
     </
   
     body
   
     >
   
     

   
     </
   
     html
   
     >
  
    

myproject.tpl (child)

  
    

   
     {extends file='layout.tpl'}
{block name=head}
 
   
     <
   
     link 
   
     href
   
     ="/css/mypage.css"
   
      rel
   
     ="stylesheet"
   
      type
   
     ="text/css"
   
     />
   
     
 
   
     <
   
     script 
   
     src
   
     ="/js/mypage.js"
   
     ></
   
     script
   
     >
   
     
{/block}
  
    

mypage.tpl (grandchild)

  
    

   
     {extends file='myproject.tpl'}
{block name=title}My Page Title{/block}
{block name=head}
 
   
     <
   
     link 
   
     href
   
     ="/css/mypage.css"
   
      rel
   
     ="stylesheet"
   
      type
   
     ="text/css"
   
     />
   
     
 
   
     <
   
     script 
   
     src
   
     ="/js/mypage.js"
   
     ></
   
     script
   
     >
   
     
{/block}
{block name=body}My HTML Page Body goes here{/block}
  
    

To render the above use

  
    

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

The resulting output is

  
    

   
     <
   
     html
   
     >
   
     

   
     <
   
     head
   
     >
   
     
 
   
     <
   
     title
   
     >
   
     My Page Title
   
     </
   
     title
   
     >
   
     
 
   
     <
   
     link 
   
     href
   
     ="/css/mypage.css"
   
      rel
   
     ="stylesheet"
   
      type
   
     ="text/css"
   
     />
   
     
 
   
     <
   
     script 
   
     src
   
     ="/js/mypage.js"
   
     ></
   
     script
   
     >
   
     

   
     </
   
     head
   
     >
   
     

   
     <
   
     body
   
     >
   
     
My HTML Page Body goes here

   
     </
   
     body
   
     >
   
     

   
     </
   
     html
   
     >
