Magento开发常用方法

这里是我做Magento开发常用到的方法，现在总结出来，后续会把更多有用的方法总结出来。

1.直接操作数据库

查找数据：
$read = Mage::getSingleton("core/resource")->getConnection('core_read');　　
$sql = "select * from `abc`";
$result = $read->fetchAll($sql);  //fetchRow查找一条
增，删，改：
$write = Mage::getSingleton("core/resource")->getConnection('core_write');
$sql = "insert into abc (name)values('hello')";
$write->query($sql);

2.Customer的Session对象的操作

Mage::getModel('customer/session')  #得到Mage_Customre_Model_Session对象
1.可以得到用户 getCustomer()方法
2.判断登录状态  isLoggedIn()方法

3.获取IP地址

$ip = Mage::helper('core/http')->getRemoteAddr()

4.Mage.php常用方法

dispatchEvent() #事件分发
getUrl()              #得到URL
getStoreConfig()#得到配置信息,定义在XML

5.常用载入数据方法

Mage::getModel('sales/order')->load();  #得到指定订单
Mage::getModel('customer/customer')->load();  #得到指定用户
Mage::getModel('catalog/product')->load();  #得到指定产品

6.得到常见集合

Mage::getModel('catalog/product')->getCollection()  #得到产品的集合
Mage::getModel('customer/customer)->getCollection()  #得到用户的集合
Mage::getModel('sales/order')->getCollection()  #得到订单集合

7.获取当前店铺信息

Mage::app()->getStore()  #得到 Mage_Core_Model_Store对象，最对象里面找对应方法得到相应店铺信息

8.得到当前产品ID

$product_id = Mage::registry('current_product')->getId()

9.得到related products

$associatedProductId = Mage::getModel('catalog/product_type_grouped')->getAssociatedProductIds($_product);
$associatedProduct = Mage::getModel('catalog/product')->load($associatedProductId[0]);

10.获取指定分类产品

$products = Mage::getModel('catalog/category')->load($category_id)
->getProductCollection()
->addAttributeToSelect('*')
->addAttributeToFilter('status', 1)
->addAttributeToFilter('visibility', 4);

11.快速开启模板提示

A.找到app/code/core/Mage/Core/Block/Template.php这个文件
B.在getShowTemplateHints这个方法里面添加 return true

12.得到分类子分类

$currCat = Mage::getModel('catalog/category')->load($id) ; //当前分类
$collection = Mage::getModel('catalog/category')->getCategories($currCat->getEntityId());

13.获取指定目录子分类

if($category->hasChildren()) {  //判断是否有子目录
 $ids = $category->getChildren();   //提取子目录id清单
 $subCategories = Mage::getModel('catalog/category')->getCollection();
 $subCategories->getSelect()->where("e.entity_id in ($ids)");  //提取指定目录ids的上当清单
 $subCategories->addAttributeToSelect('name');  //指定查找目录名称
 $subCategories->load();
 foreach ($subCategories AS $item) {
 echo " - " ;
 echo '<a href="'. $item->getUrl() . '">';   //获取目录链接
 echo $item->getName();   //获取目录名
 echo "</a>(";
 echo $item->getProductCount();   //获取目录下的产品数量
 //echo $item->getChildrenCount();  //获取目录下子目录数量
 echo ")";
 echo "<br/>";
 }
 }

14.获取URL的方法

Mage::getUrl(地址)
Mage::getUrl(地址,array())
Mage::helper('core/url')->getCurrentUrl()
Mage::helper('core/url')->getHomeUrl()
Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_LINK)                                                    

15.获取商品库存

(int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($product)->getQty()

16.首页判断

$routeName = Mage::app()->getRequest()->getRouteName();
$identifier = Mage::getSingleton('cms/page')->getIdentifier();
if ($routeName == 'cms' && $identifier == 'home')
{
    //当前页是首页
}

17.获得订单的所有item

$quote = Mage::getModel('checkout/session')->getQuote();
$items = $quote->getAllActiveItem();
$data = array();
foreach($items as $key => $item){
     $data[$key] = $item->toArray(array('属性1'，'属性2','属性3'));
}
return $data;

18.格式化价格

$price =  Mage::helper('core')--->currency($product->getPrice());
$price =  Mage::helper('checkout')->formatprice($price);

19.top.links添加

添加：
<action method="addLink" translate="label title">
                    <label>帮助中心</label>
                    <url>help</url>
                    <title>帮助中心</title>
                    <prepare>true</prepare>
                    <urlParams helper="core/url/getHomeUrl"/>
                    <position>555</position>
                    <liParams/>
                    <!--<aParams>class="top-link-about-us"</aParams>-->
                    <beforeText></beforeText>
                    <afterText></afterText>
                </action>

删除：
1、<remove name="checkout_cart_link" />
2、<action method="removeLinkByUrl"><url helper="customer/getAccountUrl"/></action>

20.获得产品的销量

$productOrderedQty = Mage::helper('catalog/product')->getQuantityOrderedBySku($Sku); 

21.cms page 加载动态数据

在design中设置如下内容:
<reference name="content">
   <block type="catalog/product_new" name="product_new" template="catalog/product/list.phtml">
      <action method="setCategoryId"><category_id>10</category_id></action>
      <action method="setColumnCount"><column_count>6</column_count></action>
      <action method="setProductsCount"><count>0</count></action>
      <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml">
         <block type="page/html_pager" name="product_list_toolbar_pager" />
         <action method="setDefaultGridPerPage"><limit>12</limit></action>
         <action method="addPagerLimit"><mode>grid</mode><limit>12</limit></action>
         <action method="addPagerLimit"><mode>grid</mode><limit>24</limit></action>
         <action method="addPagerLimit"><mode>grid</mode><limit>36</limit></action>
         <action method="addPagerLimit"><mode>grid</mode><limit>48</limit></action>
         <action method="addPagerLimit" translate="label"><mode>grid</mode><limit>all</limit><label>All</label></action>
      </block>
      <action method="addColumnCountLayoutDepend"><layout>one_column</layout><count>6</count></action>
      <action method="setToolbarBlockName"><name>product_list_toolbar</name></action>
   </block>
</reference>
或者:
{{block type="catalog/product_new" column_count="6" products_count="100" name="home.catalog.product.new" alias="product_homepage" template="catalog/product/new.phtml"}}

22.获得指定目录产品

$products=Mage::getModel('catalog/category')->load($category_id)
    ->getProductCollection()
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('status', 1)
    ->addAttributeToFilter('visibility', 4);
    

23.得到可配置产品的下属所有产品

    $product = Mage::getModel('catalog/product');
    $parent = $product->load(产品ID);
 　　$children = Mage::getModel('catalog/product_type_configurable')
                    ->getUsedProductCollection($parent);
    foreach($children as $child){
        $child = $product->load($child->getId());
        var_dump($child->getName());
    }
