自己动手写个小框架之五

     上一篇提到smarty的封装，这篇将介绍控制类对其封装的调用。控制类中有多个action函数，每个函数可以对应不同的页面，一个函数中可能根据业务逻辑对应多个页面，对页面数据的绑定也同时在action函数中绑定。我们看看defaultController.php

 1 <?php
 2 
 3 class defaultController extends Controller {
 4 
 5     public function indexAction($parameter) {
 6         $request = new request();
 7         //给session赋值
 8         $request->set("luf&d", "luf&d");
 9         $this->render('default.tpl', array("value" => $parameter[0],
10             "Name" => "index Action page",
11             "FirstName" => array("John", "Mary", "James", "Henry"),
12             "LastName" => array("Doe", "Smith", "Johnson", "Case"),
13             "contacts" => array(array("phone" => "1", "fax" => "2", "cell" => "3"),
14                 array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234"))));
15     }
16 
17     public function newAction($parameter) {
18         $this->render('default1.tpl', array("value" => $parameter[0],
19             "Name" => "new Action page"));
20     }
21 
22     public function argsAction($parameter) {
23         $this->render('default1.tpl', array("value" => $parameter[0] . $parameter[1],
24             "Name" => "new Action page"));
25     }
26 
27     public function requestAction($parameter = NULL) {
28         $request = new request();
29         //获取"luf&d"的值
30         $getinfo = $request->get("luf&d");
31         $this->render('default1.tpl', array("value" => $getinfo,
32             "Name" => "index Action page",
33             "FirstName" => array("John", "Mary", "James", "Henry"),
34             "LastName" => array("Doe", "Smith", "Johnson", "Case"),
35             "contacts" => array(array("phone" => "1", "fax" => "2", "cell" => "3"),
36                 array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234"))));
37     }
38 
39 }
40 
41 ?>

该类继承Controller类，可以操作父类的Tpl对象来调用smarty的封装方法render,从而触发smarty模板机制。例如indexAction函数

public function indexAction($parameter) 函数

给default.tpl模板赋值：value,Name,FirstName,LastName,contacts。接着，我们看看default.tpl，里面用到smarty官方的例子

tpl模板文件在tpls/templates/ 里

      在tpl文件中“<{”与“}>”成对出现，是我们封装smarty时，设置的模板标签起始和结束标志。在标记中根据前端展现需要编写页面逻辑即可。这里显示了赋值显示及一些smarty的内置函数，如显示当前系统时间、获取当前脚本、获取服务器、字符串全大写等；还有标签条件逻辑语法和循环逻辑语法的使用。

<{config_load file="test.conf" section="setup"}>
<{include file="header.tpl" title=foo}>
<PRE>
(*^__^*)<{$value}>

<{* bold and title are read from the config file *}>
<{if #bold#}><b><{/if}>
<{* capitalize the first letters of each word of the title *}>
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}>

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

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

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

An example of a section loop:

<{section name=outer 
loop=$FirstName}>
<{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:

<{section name=sec1 loop=$contacts}>
    phone: <{$contacts[sec1].phone}><br>
    fax: <{$contacts[sec1].fax}><br>
    cell: <{$contacts[sec1].cell}><br>
<{/section}>
<p>

<{include file="footer.tpl"}>

其中引入header.tpl和footer.tpl这对于整个系统统一界面很重要，加入前端美工设计后，能使整个系统的一致。还引入了test.conf

header.tpl

View Code 
1 <HTML>
2 <HEAD>
3 <TITLE><{$title}> - <{$Name}></TITLE>
4 </HEAD>
5 <BODY bgcolor="#ffffff">

footer.tpl

View Code 
1 </BODY>
2 </HTML>

conf文件在tpls/configs/里

test.conf

View Code 
1 title = Welcome to Smarty!
2 cutoff_size = 40
3 
4 [setup]
5 bold = true

 

运行效果：

在浏览器中输入路由地址http://localhost/dluf/index.php/default/index/dluf

    在系列六中将介绍对页面传值的封装。
