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

<?php

class Request {

    private $key;

    public function __construct() {
        session_start();
    }

    public function set($key, $value) {
        $this->key = $key;
        $_SESSION[$key] = $value;
    }

    public function get($key) {
        $value = "null";
        if (isset($_SESSION[$key])) {
            $value = $_SESSION[$key];
        } elseif (isset($_POST[$key])) {
            $value = $_POST[$key];
        } elseif (isset($_GET[$key])) {
            $value = $_GET[$key];
        }

        return $value;
    }

}

?>

    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。

<?php

class defaultController extends Controller {

    public function indexAction($parameter) {
        $request = new request();
        //给session赋值
        $request->set("luf&d", "luf&d");
        $this->render('default.tpl', array("value" => $parameter[0],
            "Name" => "index Action page",
            "FirstName" => array("John", "Mary", "James", "Henry"),
            "LastName" => array("Doe", "Smith", "Johnson", "Case"),
            "contacts" => array(array("phone" => "1", "fax" => "2", "cell" => "3"),
                array("phone" => "555-4444", "fax" => "555-3333", "cell" => "760-1234"))));
    }

    public function newAction($parameter) {
        $this->render('default1.tpl', array("value" => $parameter[0],
            "Name" => "new Action page"));
    }

    public function argsAction($parameter) {
        $this->render('default1.tpl', array("value" => $parameter[0] . $parameter[1],
            "Name" => "new Action page"));
    }

    public function requestAction($parameter = NULL) {
        $request = new request();
        //获取"luf&d"的值
        $getinfo = $request->get("luf&d");
        $this->render('default1.tpl', array("value" => $getinfo,
            "Name" => "request Action page"));
    }

}

?>

    default1.tpl模板页为：

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

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

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