正确处理页面控制器woopagecontroller.php，当提交表单时是否跳转正确的页面

第二个文件页面控制器woopagecontroller.php

<?php
require("Registry.php");
require("woodomainvenue.php");
abstract class woo_controller_PageController{
    
	private $request;
	function __construct(){
    
		$request=woo_base_RequestRegistry::getRequest();
		if(is_null($request)){
    $request=new woo_controller_Request();}
		$this->request=$request;
	}
	abstract function process();
	function forward($resource){
    
		include($resource);
		exit(0);
	}
	function getRequest(){
    
		return $this->request;
	}
}
class woo_controller_AddVenueController extends woo_controller_PageController{
    
	function process(){
    
		try{
    
			$request=$this->getRequest();
			$name=$request->getProperty('venue_name');
			if(is_null($request->getProperty('submitted'))){
    
				$request->setFeedback("choose a name for the venue");
				$this->forward("addvenue.php");
			}else if($name==''){
    
				$request->setFeedback("name is a required field");
				$this->forward("addvenue.php");
			}else{
    
				$venue=new woo_domain_Venue(null,$name);
				$this->forward("listvenue.html");
				//return $venue;
			}
			
		}catch(Exception $e){
    
			$this->forward('error.php');
		}
	}
}
$controller=new woo_controller_AddVenueController();
$controller->process();
?>

第三个文件addvenue.php文件，在浏览器中访问addvenue.php,当提交给woopagecontroller.php处理时会正确跳转到指定的文件listvenue.html

<html>
<head>
<title>Add Venue</title>
</head>
<body>
<h1>Add Venue</h1>
<table>
<tr>
</td>

</td>
</tr>
</table>
<form action="woopagecontroller.php" method="get">
	<input type="submit" name="submitted" value="提交"/>
	<input type="text" name="venue_name"/>
</form>
</body>
</html>
