摘要: Magento模块开发的简单示例

Magento模块开发的简单示例

开发模式下开启日志记录,方便调试。

System->Developer

magento/var 要开启777权限,/var/log目录下能看到(exception.log,system.log)。


模块文件 (Xinson 为Packagename,News为Modulename)

Packagename_All.xml的命名表示Package中开启多个模块

/app/etc/modules/Xinson_News.xml

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


在loacl新建相关目录


模块的配置文件

/app/code/local/Xinson/News/etc/config.xml 

<?xml version="1.0"?>
<config>
    <modules>
        <Xinson_News>
            <version>0.1.0</version>
        </Xinson_News>
    </modules>
</config>


添加安装文件

/app/code/local/Xinson/News/sql/news_setup/mysql4-install-0.1.0.php

<?php

$installer = $this;
$installer->startSetup();
$installer->run("
-- DROP TABLE IF EXISTS {$this->getTable('news')};
CREATE TABLE {$this->getTable('news')} (
  `news_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL DEFAULT '',
  `content` text NOT NULL DEFAULT '',
  `created_at` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  `updated_at` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
  `is_active` tinyint(1) unsigned NOT NULL DEFAULT '1',
  PRIMARY KEY (`news_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    ");
$installer->endSetup();

在config.xml配置文件,resources为执行news_setup里的文件(相关数据库操作,版本更新),translate为语言包(Xinson_News.csv放在app/locale/zh_CN里面)

<config>    
    <global>    
        <resources>
            <news_setup>
                <setup>
                    <module>Xinson_News</module>
                </setup>
                <connection>
                    <use>core_setup</use>
                </connection>
            </news_setup>
        </resources>
        <translate>
            <modules>
                <Xinson_News>
                    <files>
                        <default>Xinson_News.csv</default>
                    </files>
                </Xinson_News>
            </modules>
        </translate>
    </global>
</config>


此时进入后台,清除缓存。

在system->Configuration->Mage Trash App->Extensions Installed

可以看到Xinson_News。

并且在core_resource表中能看到,xinson_setup  0.1.0  0.1.0。还有新建的表news。


在config.xml中添加资源

global表示全局,即前台,后台都能使用。adminhtml为后台,frontend为前台。

<config>
    <global>
        <resources>
            ......
            <news_write>
                <connection>
                    <use>core_write</use>
                </connection>
            </news_write>
            <news_read>
                <connection>
                    <use>core_read</use>
                </connection>
            </news_read>
        </resources>
    </global>
</config>


添加Model

/app/code/local/Xinson/News/Model/News.php

<?php

class Xinson_News_Model_News extends Mage_Core_Model_Abstract
{
    public function _construct()
    {
        parent::_construct();
        $this->_init('news/news');
    }
}

/app/code/local/Xinson/News/Model/Mysql4/News.php

<?php

class Xinson_News_Model_Mysql4_News extends Mage_Core_Model_Mysql4_Abstract
{
    public function _construct()
    {
        $this->_init('news/news', 'news_id');
    }
}

/app/code/local/Xinson/News/Model/Mysql4/News/Collection.php

<?php

class Xinson_News_Model_Mysql4_News_Collection extends Mage_Core_Model_Mysql4_Collection_Abstract
{
    public function _construct()
    {
        parent::_construct();
        $this->_init('news/news');
    }
}


在config.xml中添加Model(在global里面)

<global> 
    <models>
        <news>
            <class>Xinson_News_Model</class>
            <resourceModel>news_mysql4</resourceModel>
        </news>
        <news_mysql4>
            <class>Xinson_News_Model_Mysql4</class>
            <entities>
                <news>
                    <table>news</table>
                </news>
            </entities>
        </news_mysql4>
    </models>
</global>


添加Helper和Block

/app/code/local/Xinson/News/Helper/Data.php

<?php

class Xinson_News_Helper_Data extends Mage_Core_Helper_Abstract
{

}

在config.xml中添加Helper和Block

<config>
    <global>
        <blocks>
            <news>
                <class>Xinson_News_Block</class>
            </news>
        </blocks>
        <helpers>
            <news>
                <class>Xinson_News_Helper</class>
            </news>
        </helpers>
    </global>
</config>


添加样例数据和前段控制器

进入MYSQL执行

INSERT INTO `news` (`title`, `content`, `created_at`, `updated_at`, `is_active`) VALUES ('title1', 'content1', '2015-11-29 08:00:00', '2015-11-29 08:00:00', 1);
INSERT INTO `news` (`title`, `content`, `created_at`, `updated_at`, `is_active`) VALUES ('title2', 'content2', '2015-11-29 08:10:00', '2015-11-29 08:10:00', 1);

前端控制器

/app/code/local/Xinson/News/controllers/IndexController.php

<?php

class Xinson_News_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
        $news = Mage::getModel('news/news')->getCollection();
        foreach ($news as $new) {
            var_dump($new->getData());
        }
    }
}

config.xml路由配置

<config>
    <frontend>
        <routers>
            <news>
                <use>standard</use>
                <args>
                    <module>Xinson_News</module>
                    <frontName>news</frontName>
                </args>
            </news>
        </routers>
    </frontend>
</config>


在浏览器中打开 http://localhost/news 将看到var_dump的数据


此时的config配置文件

<?xml version="1.0"?>
<config>

    <modules>
        <Xinson_News>
            <version>0.1.0</version>
        </Xinson_News>
    </modules>

    <global>
        <resources>
            <news_setup>
                <setup>
                    <module>Xinson_News</module>
                </setup>
                <connection>
                    <use>core_setup</use>
                </connection>
            </news_setup>
            <news_write>
                <connection>
                    <use>core_write</use>
                </connection>
            </news_write>
            <news_read>
                <connection>
                    <use>core_read</use>
                </connection>
            </news_read>
        </resources>
        <models>
            <news>
                <class>Xinson_News_Model</class>
                <resourceModel>news_mysql4</resourceModel>
            </news>
            <news_mysql4>
                <class>Xinson_News_Model_Mysql4</class>
                <entities>
                    <news>
                        <table>news</table>
                    </news>
                </entities>
            </news_mysql4>
        </models>

        <translate>
            <modules>
                <Xinson_News>
                    <files>
                        <default>Xinson_News.csv</default>
                    </files>
                </Xinson_News>
            </modules>
        </translate>

        <blocks>
            <news>
                <class>Xinson_News_Block</class>
            </news>
        </blocks>

        <helpers>
            <news>
                <class>Xinson_News_Helper</class>
            </news>
        </helpers>

    </global>

    <frontend>
        <routers>
            <news>
                <use>standard</use>
                <args>
                    <module>Xinson_News</module>
                    <frontName>news</frontName>
                </args>
            </news>
        </routers>
    </frontend>
