    打开后台可以看到：
    图片描述
    这里需要注意的是，在Grid.php中有这么一句代码'renderer' =>'Test_Lesson_Block_Adminhtml_Template_Grid_Renderer_Image',涉及到图片的上传，所以，所以还需要新增一个Image.php

    <?php
class Test_Lesson_Block_Adminhtml_Template_Grid_Renderer_Image extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{
    public function render(Varien_Object $row)
    {
        //$val = Mage::helper('catalog/image')->init($row, 'thumbnail')->resize(97);
        //$out = "<img src=". $val ." width='97px'/>";
        //return $out;
        $html  = '<img ';
        $html .= 'id="' . $this->getColumn()->getId() . '" ';
        $html .= 'src="' . $row->getData($this->getColumn()->getIndex()) . '" ';
        $html .=  'width="80" height="60"';
        $html .= 'class="grid-image ' . $this->getColumn()->getInlineCss() . '"/>';
        return $html;
    }
}

    接着，就需要保存，就需要重新后台控制器中的saveAction(方法，同时新增image上传.
    路径：Test/Lesson/controllers/Adminhtml/Awblog/Manage/BlogController.php

    <?php
require_once "AW/Blog/controllers/Adminhtml/Awblog/Manage/BlogController.php";//重写控制器，这句不能少

    所需要的功能基本完成了，剩下来，就是需要将数据在前台展示出来，需要新建Helper类，Model和新增的数据表字段，依次将它们新建起来：
    Helper/Data.php

    <?php
class Test_Lesson_Helper_Data extends Mage_Core_Helper_Abstract
{
}

    Model/Status.php

    <?php
class Test_Lesson_Model_Status extends Mage_Core_Model_Abstract

    /*
    *changestatus截止时间过期后改变状态
    */
    public function changeStatus()
    {
        $model = Mage::getModel('blog/blog')->getCollection();
        $data = $model->getData();
        foreach ($data as $val) {
            $currentDate = strtotime(date('Y-m-d'));
            $dateline = strtotime(Mage::app()->getLocale()->date($val['endtime'])->toString('YYYY-MM-dd'));
            $poorDate = floor(($dateline - $currentDate) / (3600 * 24));
            $connection = Mage::getSingleton('core/resource')->getConnection('core_write');
            $table = $connection->getTableName('aw_blog');
            if ($poorDate >= 0) {
                $sql = "UPDATE {$table} SET isexpiry=1 WHERE post_id=" . $val['post_id'];
            } else {
                $sql = "UPDATE {$table} SET isexpiry=0 WHERE post_id=" . $val['post_id'];
            }
            $connection->query($sql);
        }
        //return $sql;
    }

$installer = $this;
$installer->StartSetup();
$sql="ALTER TABLE 'aw_blog' ADD imagepath VARCHAR(255) NOT NULL,ADD endtime datetime DEFAULT NULL,ADD isexpiry tinyint DEFAULT  NULL";
$installer->run($sql);
$installer->EndSetup();

    接着，来写前台的内容，前台的页面展示，需要设计到Block和IndexController控制器,所以，也一并写好：
    IndexController.php

    <?php
class Test_Lesson_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
        $this->loadLayout();
        //$this->_title('lesson')->_title('index');
        $this->renderLayout();
 
    }
    public function applicationAction()
    {
        $this->loadLayout();
        $this->renderLayout();

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

    Block下的文件Left.php,Video.php,Cource.php,Application.php
    路径：Block/Left.php

    <?php
class Test_Lesson_Block_Left extends Mage_Core_Block_Template
{}

    路径：Block/Cource.php

    <?php
class Test_Lesson_Block_Cource extends Mage_Core_Block_Template
{
    public function _prepareLayout()
    {
        $status = Mage::getModel('lesson/status')->changeStatus();
        //$status = Mage::getModel('lesson/status');
        $model =  Mage::getModel('blog/blog')->getCollection();
        $model->addFieldtoFilter('status',AW_Blog_Model_Status::STATUS_ENABLED)
            ->addFieldtoFilter('isexpiry',1);
        $model->setOrder('created_time','DESC');
        $this->setCollection($model);
        return $this;
    }
     
    /*
     *page 
     */
    public function bindPager($pagerName)
    {
        $pager = $this->getLayout()->getBlock($pagerName);
        if ($pager) {
            $pager->setLimit(2); // 设置每页显示新闻的数量
            $pager->setCollection($this->getCollection());
            $pager->setShowPerPage(false);
        }
    } 

}

    Block/Video.php

    <?php
class Test_Lesson_Block_Video extends Mage_Core_Block_Template
{
    public function _prepareLayout()
    {
        $status = Mage::getModel('lesson/status')->changeStatus();
        $model =  Mage::getModel('blog/blog')->getCollection();
        $model->addFieldtoFilter('status',AW_Blog_Model_Status::STATUS_ENABLED)->addFieldtoFilter('isexpiry','0');
        $model->setOrder('created_time','ASC');
        $this->setCollection($model);
        return $this;
    }

    /*
     *page
     */
    public function bindPager($pagerName)
    {
        $pager = $this->getLayout()->getBlock($pagerName);
        if ($pager) {
            $pager->setLimit(2); // 设置每页显示新闻的数量
            $pager->setCollection($this->getCollection());
            $pager->setShowPerPage(false);
        }
    }

}

    Block/Application.php

    class Test_Lesson_Block_Application extends Mage_Core_Block_Template
{
    public function test()
    {
        return "this is application content";
    }
}

    现在就只剩下design前台展示部分了。
