smarty模板引擎之配置文件数据和保留数据,smarty模板

本文实例讲述了smarty模板引擎之配置文件数据和保留数据的方法。分享给大家供大家参考。具体如下:

一、如何让模板直接从配置文件中取出数据

1.使用场合

当某个变量值,不希望直接写死到程序中(通过smarty分配),就可以通过配置文件来获取。

2.写配置文件

新建文件夹:config
新建文件名:my.ini或my.config
内容:key=value;

例子:

title="This is the title of the website."
bgcolor="pink"

3.使用方法

载入配置文件:{config_laod file="路径"}
使用配置文件数据:

例子:

{config_laod file="my.config"}
<body bgcolor='<{#bgcolor#}>'>...</body>

二、如何获得保留变量的数据

即,如何取得get/post/session/server数据。这些数据是保存在数组中的,smarty封装了方法,可以直接通过smarty变量进行获取。

1.获得get数据

传统方式:先取得get数据,再分配给smarty。但是smarty本身封装了方法,不用分配,就可以直接获得get数据。

使用方法如下:

用户名:<{$smarty.get.username}><br/>
密码:<{$smarty.get.password}><br/>

2.获得post数据

使用方法如下:

用户名:<{$smarty.post.username}><br/>
密码:<{$smarty. post.password}><br/>

3.获得server数据

使用方法如下:

服务器名称:<{$smarty.server.SERVER_NAME}>

希望本文所述对大家的php程序设计有所帮助。
