zend framework 报错定义页面

确保index.php中有如下内容：
$plugin = new Zend_Controller_Plugin_ErrorHandler();
$plugin->setErrorHandlerModule('frontController')
->setErrorHandlerController('Error')
->setErrorHandlerAction('error');

$frontController = Zend_Controller_Front::getInstance();//取得Zend_Controller_Front类实例
$frontController->registerPlugin($plugin);
$frontController->setControllerDirectory (array(
"default" => 'application/controllers',
)); // 指定一组控制器文件路径，参数是数组。设置前端控制器，主要是让控制器知道我们的的控制器类在哪里
$frontController->throwExceptions(false);//让前端控制器抛出所有的异常。 默认情况下，前端控制器将捕获这些异常并将其人传递到 ErrorController 控制器，在开发过程，这样错误容易发现。但在实际运行中，不能将这些错误直接显示给前端用户。
$frontController->setParam('noViewRenderer', true);// 指明不使用视图，false 是默认值。
$frontController->setParam('noErrorHandler', false);
$frontController->dispatch(); //程序执行分发
新建一个控制器ErrorController.php
require_once 'Zend/Controller/Action.php';
//默认错误控制器类
class ErrorController extends Zend_Controller_Action{
public function init()
{
$this->registry = Zend_Registry::getInstance();
$this->view = $this->registry['view'];
$this->view->baseUrl = $this->_request->getBaseUrl();
}
/**
* This action handles
* - Application errors
* - Errors in the controller chain arising from missing
* controller classes and/or action methods
*/
public function errorAction(){
//动作方法名：对应的文件是views/scripts/error/error.phtml
$errors = $this->_getParam('error_handler');
switch ($errors->type) {
case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
// 404 error -- controller or action not found
//$this->getResponse()->setRawHeader('HTTP/1.1 404 Not Found!!!');//当这行起作用时候，在ie6下会出现它自身默认的404显示。
$content= 'The page you request was not found! ';
break;
default:
// application error; display error page, but don't change
// status code
$content = 'Application Error';
break;
}
$this->getResponse()->clearbody();
$this->view->message = $content;
echo $this->view->render('error/error.phtml');//显示增加模版
}
}
新建错误视图application/views/scripts/error/error.phtml
<?php echo $this->message;?>Please <a href="<?php echo $this->baseUrl; ?>">GoBack</a>
