下面的模块是获取一个或者多个数据的使用方法
- 建立modules
D:\www\ysqmagento1938\app\etc\modules\Infinity_Helloworld.xml
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<Infinity_Helloworld>
<active>true</active>
<codePool>local</codePool>
</Infinity_Helloworld>
</modules>
</config>
2 . 建立config.xml 配置文件
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\etc\config.xml
<?xml version="1.0" encoding="UTF-8"?>
<config>
<!--设置模块 start-->
<modules>
<Infinity_Helloworld>
<version>0.2.0</version>
</Infinity_Helloworld>
</modules>
<!--end-->
<!--设置前端路由start-->
<frontend>
<routers>
<helloworld>
<use>standard</use>
<args>
<module>Infinity_Helloworld</module>
<frontName>helloworld</frontName>
</args>
</helloworld>
</routers>
</frontend>
<!--end-->
<global>
<!--数据模型设置start-->
<models>
<helloworld>
<class>Infinity_Helloworld_Model</class>
<resourceModel>helloworld_mysql4</resourceModel>
</helloworld>
<helloworld_mysql4>
<class>Infinity_Helloworld_Model_Resource_Mysql4</class>
<entities>
<blogpost>
<table>blog_posts</table>
</blogpost>
</entities>
</helloworld_mysql4>
</models>
<!--数据模型设置end-->
<resources>
<!--写读适配器，默认可以不设置-->
<helloworld_write>
<connection>
<use>default_write</use>
</connection>
</helloworld_write>
<helloworld_read>
<connection>
<use>default_read</use>
</connection>
</helloworld_read>
</resources>
</global>
</config>
3. 建立控制器
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\controllers\BlogController.php
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\controllers\IndexController.php
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\controllers\MessagesController.php控制器下面建立方法
<?php
/**
* Created by PhpStorm.
* User: lollicup
* Date: 2019/4/24
* Time: 14:22
*/
class Infinity_Helloworld_BlogController extends Mage_Core_Controller_Front_Action {
/**
* 获取数据集合
*/
public function showAllBlogPostsAction() {
$posts = Mage::getModel('helloworld/blogpost')->getCollection();
foreach($posts as $blog_post){
echo '<h3>'.$blog_post->getTitle().'</h3>';
echo nl2br($blog_post->getPost());
}
}
}<?php
/**
* @Author: ysqgit
* @Date: 2019-04-20 16:20:09
* @Last Modified by: ysqgit
* @Last Modified time: 2019-04-21 00:25:01
*/
class Infinity_Helloworld_IndexController extends Mage_Core_Controller_Front_Action {
public function indexAction() {
// $blogpost = Mage::getModel('helloworld/blogpost');
// var_dump($blogpost);
// echo get_class($blogpost);
// echo 'Hello World!';
// $this->loadLayout();
// $this->renderLayout();
//获取单条数据
$params = $this->getRequest()->getParams();
$blogpost = Mage::getModel('helloworld/blogpost');
echo("Loading the blogpost with an ID of ".$params['id']."<br />");
echo "<br/>";
$blogpost->load($params['id']);
$data = $blogpost->getData();
print_r($data);
echo "<br/>";
print_r($blogpost->getData('title'));
echo "<br/>";
print_r($blogpost->getOrigData());
echo "<br/>";
print_r($blogpost->getOrigData('title'));
}
//添加数据
public function createNewPostAction() {
$blogpost = Mage::getModel('helloworld/blogpost');
$blogpost->setTitle('Code Post!');
$blogpost->setPost('This post was created from code!');
$blogpost->save();
echo 'post created';
}
//修改数据保存
public function editFirstPostAction() {
$blogpost = Mage::getModel('helloworld/blogpost');
$blogpost->load(1);
$blogpost->setTitle("The First post ttt!");
print_r ($blogpost->save());
echo 'post edited';
}
//删除数据
public function deleteFirstPostAction() {
$blogpost = Mage::getModel('helloworld/blogpost');
$blogpost->load(1);
$blogpost->delete();
echo 'post removed';
}
public function goodbyeAction() {
//echo 'Goodbye World!';
$this->loadLayout();
$this->renderLayout();
}
public function paramsAction() {
echo '<dl>';
foreach($this->getRequest()->getParams() as $key=>$value) {
echo '<dt><strong>Param: </strong>'.$key.'</dt>';
echo '</dl><dl><strong>Value: </strong>'.$value.'</dl>';
}
echo '';
}
}
<?php
/**
* @Author: ysqgit
* @Date: 2019-04-20 16:44:18
* @Last Modified by: ysqgit
* @Last Modified time: 2019-04-20 16:45:19
*/
class Infinity_Helloworld_MessagesController extends Mage_Core_Controller_Front_Action{
public function goodbyeAction()
{
echo 'Another Goodbye';
}
}
4、建立如下model文件
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\Model\Blogpost.php
<?php
/**
* Created by PhpStorm.
* User: lollicup
* Date: 2019/4/24
* Time: 13:48
*/
class Infinity_Helloworld_Model_Blogpost extends Mage_Core_Model_Abstract
{
protected function _construct()
{
$this->_init('helloworld/blogpost');
}
}
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\Model\Resource\Mysql4\Blogpost.php
<?php
/**
* Created by PhpStorm.
* User: lollicup
* Date: 2019/4/24
* Time: 13:52
*/
class Infinity_Helloworld_Model_Resource_Mysql4_Blogpost extends Mage_Core_Model_Mysql4_Abstract{
protected function _construct()
{
$this->_init('helloworld/blogpost', 'blogpost_id');
}
}
D:\www\ysqmagento1938\app\code\local\Infinity\Helloworld\Model\Resource\Mysql4\Blogpost\Collection.php
<?php
/**
* Created by PhpStorm.
* User: lollicup
* Date: 2019/4/24
* Time: 14:25
*/
class Infinity_Helloworld_Model_Resource_Mysql4_Blogpost_Collection extends Mage_Core_Model_Mysql4_Collection_Abstract {
protected function _construct()
{
$this->_init('helloworld/blogpost');
}
}
