Magento 管理员布局和模板

Question

我是 Magento 的新手。我正在学习 Magento 模块开发。我正在尝试遵循这个 (http://www.opensourceforwebtechnologies.com/create-custom-admin-module-in-magento/) 教程。在这方面，我的代码如下。

Easylife_All.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Easylife_Helloworld>
            <active>true</active>
            <codePool>local</codePool>
        </Easylife_Helloworld>
    </modules>
</config>

这个文件的位置是

config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Easylife_Helloworld>
            <version>0.1.0</version>
        </Easylife_Helloworld>
    </modules>
    <frontend>
        <routers>
            <helloworld>
                <use>standard</use>
                <args>
                    <module>Easylife_Helloworld</module>
                    <frontName>helloworld</frontName>
                </args>
            </helloworld>
        </routers>
        <layout>

        </layout>
        <menu>
            <helloworld translate="title" module="adminhtml">

                    </set_time>
                </children>
            </helloworld>
        </menu>
    </adminhtml>

                </connection>
            </helloworld_write>
        </resources>
    </global>
</config>

这个文件的位置

IndexController.php

class Easylife_Helloworld_Adminhtml_IndexController extends Mage_Adminhtml_Controller_Action
{

    public function indexAction()
    {
        $this->loadLayout();
        $this->renderLayout();
    }

}

这个文件的位置是

helloworld.xml

<?xml version="1.0"?>
<layout version="0.1.0">
    <helloworld_adminhtml_index_index>
        <reference name="content">
            <block name="helloworld_grid" type="helloworld/adminhtml_grid" template="helloworld/helloworld.phtml"></block>
        </reference>
    </helloworld_adminhtml_index_index>
</layout>

此文件的位置

helloworld.phtml

<h1>Success!!!!!!!!!!!!!</h1>

这个文件的位置

我正在尝试浏览以下网址

http://localhost/magento/index.php/admin_helloworld/adminhtml_index/index/key/0c82140c8238734651f876e83e2522f5/

我得到如下所示的空白页

谁能说出为什么会这样？

谢谢

更新

阻止文件夹

块文件夹的位置

Helloworld.php

<?php

class Easylife_Helloworld_Block_Helloworld extends Mage_Core_Block_Template
{
    public function Test_Method()
    {
        $result = '';
        $collection = Mage::getModel('helloworld/helloworld')->getCollection()->setOrder('id', 'asc');
        foreach ($collection as $data)
        {
            $result .= $data->getData('firstname') . ' ' . $data->getData('lastname') . ' ' . $data->getData('phone') . '<br />';
        }
        Mage::getSingleton('adminhtml/session')->addSuccess('Success!!');
        return $result;
    }
}

在 controller/Adminhtml 中创建一个名为 HelloworldController.php 的新文件并在该文件中编写代码

class Easylife_Helloworld_Adminhtml_HelloworldController extends Mage_Adminhtml_Controller_Action{

public function indexAction()
{
    $Block = $this->getLayout()->createBlock('helloworld/adminhtml_helloworld');
    $this->loadLayout()
        ->_addContent($Block)
        ->renderLayout(); 
}  }

并在 block/adminhtml/Helloworld/Edit 创建一个文件使用以下代码创建 Form.php 文件

class Easylife_Helloworld_Block_Adminhtml_Helloworld_Edit_Form extends Mage_Adminhtml_Block_Widget_Form{
 protected function _prepareForm()
 {
    echo "11111111";
   return parent::_prepareForm();
 }}
