MVC架构学习之Smarty学习病来而蔫 - 韧还

前两天是五一小长假，而每次假期都想着如何如何刻苦一番，往往是自作多情。。

当然这次是有小病在身，多个借口吧。

一有病就蔫的不行。。。要锻炼了啊，脚估计也差不多了，游泳试试吧这周。

这次学习Smarty引擎。

 

一、视图引擎简介

帮助用户实现MVC中View的开发。

（可以理解为View的模板

--好的视图引擎

贴近html；

语法简单易懂；

良好的缓存机制；

拓展性良好；

网络资源多

（所以先学习已有的视图引擎）

--知名的

Smarty，PHPLIB

二、Smarty简介

提供了逻辑和外在内容的分离（PHP程序员和美工工作的分离；

百度的介绍

然后直接官网或者github下载就好；

其中，demo就是官方给的例子，据说挺不错的；

libs里面是我们要引入的文件，如下：

Smarty.class.php就是实例化要用到的；plugins是插件，可以自己写写放进来用；

三、Smarty的引入、配置与实例制作

1、引入与实例化

首先，还是我个人的环境，前面说过：PHP5.4（忘记了）+Zend+wampserver

创建项目，把demo和libs的东西都放进来

然后在index.php中进行代码编写；

参考Smarty.class.php的代码规范，我写了个人的表头

<span style="color: #008080;"> 1</span> <span style="color: #000000;">php
</span><span style="color: #008080;"> 2</span> <span style="color: #008000;">/*</span><span style="color: #008000;">*
</span><span style="color: #008080;"> 3</span> <span style="color: #008000;"> * Project: MVCSmartyTry
</span><span style="color: #008080;"> 4</span> <span style="color: #008000;"> * File: index.php
</span><span style="color: #008080;"> 5</span> <span style="color: #008000;"> * 
</span><span style="color: #008080;"> 6</span> <span style="color: #008000;"> * This file is the test file of using Smarty.
</span><span style="color: #008080;"> 7</span> <span style="color: #008000;"> * 
</span><span style="color: #008080;"> 8</span> <span style="color: #008000;"> * @copyright Andy Liang
</span><span style="color: #008080;"> 9</span> <span style="color: #008000;"> * @author Andy Liang
</span><span style="color: #008080;">10</span> <span style="color: #008000;"> * @package   Smarty
</span><span style="color: #008080;">11</span> <span style="color: #008000;"> * @version   3.1.30-dev
</span><span style="color: #008080;">12</span>  <span style="color: #008000;">*/</span>

 

然后就是简单的引入和实例化

<span style="color: #008080;"> 1</span> <span style="color: #000000;">namespace MVCSmarty\index;
</span><span style="color: #008080;"> 2</span> <span style="color: #008000;">/*</span><span style="color: #008000;">*
</span><span style="color: #008080;"> 3</span> <span style="color: #008000;"> * Require the main file of Smarty
</span><span style="color: #008080;"> 4</span>  <span style="color: #008000;">*/</span>
<span style="color: #008080;"> 5</span> <span style="color: #0000ff;">require</span> 'Smarty.class.php'<span style="color: #000000;">;
</span><span style="color: #008080;"> 6</span>  
<span style="color: #008080;"> 7</span> <span style="color: #008000;">/*</span><span style="color: #008000;">*
</span><span style="color: #008080;"> 8</span> <span style="color: #008000;"> * Instantiation of Smarty
</span><span style="color: #008080;"> 9</span>  <span style="color: #008000;">*/</span>
<span style="color: #008080;">10</span> <span style="color: #800080;">$smarty</span>=<span style="color: #0000ff;">new</span> \Smarty();

 

注意，实例化的时候可以去看下.class.php中具体的类名什么的；然后require和include的选择也不再赘述，上文说过；

一般来说实例化感觉都是没有最后那个反斜杠的，可能是Zend的毛病，我再查查看吧。

2、配置相关

这个特殊的类，搞了一大堆属性和方法，网上有很多配置教程，这里提几个常用的东西；

尤其是两个方法：display和assign

<span style="color: #008080;"> 1</span> <span style="color: #008000;">/*</span><span style="color: #008000;">*
</span><span style="color: #008080;"> 2</span> <span style="color: #008000;"> * Configuration of Smarty
</span><span style="color: #008080;"> 3</span> <span style="color: #008000;"> * Especially five configs & two functions
</span><span style="color: #008080;"> 4</span>  <span style="color: #008000;">*/</span>
<span style="color: #008080;"> 5</span> <span style="color: #800080;">$smarty</span>->left_delimiter = "{"<span style="color: #000000;">;
</span><span style="color: #008080;"> 6</span> <span style="color: #800080;">$smarty</span>->right_delimiter = "}"<span style="color: #000000;">;
</span><span style="color: #008080;"> 7</span> <span style="color: #008000;">//</span><span style="color: #008000;">其实看源码会发现：和源码中配置的是一样的；
</span><span style="color: #008080;"> 8</span> <span style="color: #008000;">//然后还有就是templates模板文件存放地址
</span><span style="color: #008080;"> 9</span> <span style="color: #008000;">//templates_c模板编译生成的文件
</span><span style="color: #008080;">10</span> <span style="color: #008000;">//这两个是protected或者private
</span><span style="color: #008080;">11</span> <span style="color: #008000;">//这个版本的Smarty中这些设定的修改都是有方法的
</span><span style="color: #008080;">12</span> <span style="color: #008000;">//比如setTemplateDir，好像是这个
</span><span style="color: #008080;">13</span> <span style="color: #008000;">//总之多看源码</span>
<span style="color: #008080;">14</span> <span style="color: #800080;">$smarty</span>->cache_lifetime = 120<span style="color: #000000;">;
</span><span style="color: #008080;">15</span> 
<span style="color: #008080;">16</span> <span style="color: #008000;">/*</span><span style="color: #008000;">*
</span><span style="color: #008080;">17</span> <span style="color: #008000;"> * The most frequently-used methods.
</span><span style="color: #008080;">18</span>  <span style="color: #008000;">*/</span>
<span style="color: #008080;">19</span> <span style="color: #800080;">$smarty</span>->assign('articleTitle', '文章标题'<span style="color: #000000;">);
</span><span style="color: #008080;">20</span> <span style="color: #800080;">$smarty</span>->display('./templates/test.tpl');

 

assign就是个赋值，但是是在模板中的赋值；

display，顾名思义就是展示了；

给你看demo

<span style="color: #000000;">php
</span><span style="color: #008000;">/*</span><span style="color: #008000;">*
 * Example Application
 *
 * @package Example-application
 </span><span style="color: #008000;">*/</span>

<span style="color: #0000ff;">require</span> '../Smarty.class.php'<span style="color: #000000;">;

</span><span style="color: #800080;">$smarty</span> = <span style="color: #0000ff;">new</span><span style="color: #000000;"> Smarty;

</span><span style="color: #008000;">//</span><span style="color: #008000;">$smarty->force_compile = true;</span>
<span style="color: #800080;">$smarty</span>->debugging = <span style="color: #0000ff;">true</span><span style="color: #000000;">;
</span><span style="color: #800080;">$smarty</span>->caching = <span style="color: #0000ff;">true</span><span style="color: #000000;">;
</span><span style="color: #800080;">$smarty</span>->cache_lifetime = 120<span style="color: #000000;">;

</span><span style="color: #800080;">$smarty</span>->assign("Name", "Fred Irving Johnathan Bradley Peppergill", <span style="color: #0000ff;">true</span><span style="color: #000000;">);
</span><span style="color: #800080;">$smarty</span>->assign("FirstName", <span style="color: #0000ff;">array</span>("John", "Mary", "James", "Henry"<span style="color: #000000;">));
</span><span style="color: #800080;">$smarty</span>->assign("LastName", <span style="color: #0000ff;">array</span>("Doe", "Smith", "Johnson", "Case"<span style="color: #000000;">));
</span><span style="color: #800080;">$smarty</span>->assign("Class", <span style="color: #0000ff;">array</span>(<span style="color: #0000ff;">array</span>("A", "B", "C", "D"), <span style="color: #0000ff;">array</span>("E", "F", "G", "H"), <span style="color: #0000ff;">array</span>("I", "J", "K", "L"),
                               <span style="color: #0000ff;">array</span>("M", "N", "O", "P"<span style="color: #000000;">)));

</span><span style="color: #800080;">$smarty</span>->assign("contacts", <span style="color: #0000ff;">array</span>(<span style="color: #0000ff;">array</span>("phone" => "1", "fax" => "2", "cell" => "3"),
                                  <span style="color: #0000ff;">array</span>("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234"<span style="color: #000000;">)));

</span><span style="color: #800080;">$smarty</span>->assign("option_values", <span style="color: #0000ff;">array</span>("NY", "NE", "KS", "IA", "OK", "TX"<span style="color: #000000;">));
</span><span style="color: #800080;">$smarty</span>->assign("option_output", <span style="color: #0000ff;">array</span>("New York", "Nebraska", "Kansas", "Iowa", "Oklahoma", "Texas"<span style="color: #000000;">));
</span><span style="color: #800080;">$smarty</span>->assign("option_selected", "NE"<span style="color: #000000;">);

</span><span style="color: #800080;">$smarty</span>->display('index.tpl');

3、Demo学习
