自己动手写个小框架之六

    系统开发中常常会使用页面传值，我们可以进行适当的封装，以方便使用。在kernel/request.php中

 1 <?php
 2 
 3 class Request {
 4 
 5     private $key;
 6 
 7     public function __construct() {
 8         session_start();
 9     }
10 
11     public function set($key, $value) {
12         $this->key = $key;
13         $_SESSION[$key] = $value;
14     }
15 
16     public function get($key) {
17         $value = "null";
18         if (isset($_SESSION[$key])) {
19             $value = $_SESSION[$key];
20         } elseif (isset($_POST[$key])) {
21             $value = $_POST[$key];
22         } elseif (isset($_GET[$key])) {
23             $value = $_GET[$key];
24         }
25 
26         return $value;
27     }
28 
29 }
30 
31 ?>

    在控制类中，我们在indexAction中赋值，在requestAction中获取该值。其中，indexAction对default.tpl进行渲染而requestAction对default1.tpl进行渲染。

View Code 
 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" => "request Action page"));
33     }
34 
35 }
36 
37 ?>

    default1.tpl模板页为：

 1 <{config_load file="test.conf" section="setup"}>
 2 <{include file="header.tpl" title=foo}>
 3 <PRE>
 4 ^_^<{$value}>
 5 
 6 <{* bold and title are read from the config file *}>
 7 <{if #bold#}><b><{/if}>
 8 <{* capitalize the first letters of each word of the title *}>
 9 Title: <{#title#|capitalize}>
10 <{if #bold#}></b><{/if}>
11 
12 The value of <{ldelim}>$Name<{rdelim}> is <b><{$Name}></b>
13 
14 <b><{$Name|upper}></b>
15 
16 <{include file="footer.tpl"}>

运行结果：

      在浏览器输入地址：http://localhost/dluf/index.php/default/request

    在系列七中将介绍.htaccess设置，配合路由类限制访问入口。
