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。
