Magento 常用技巧与方法

1. 得到产品，以及过滤：

getResourceModel('catalog/product_collection')
$collection = Mage::getModel('catalog/product')->getCollection();
->Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection

 

2.取得属性集，属性过滤

   $attributes = Mage::getSingleton('catalog/config')
    ->getProductAttributes();
   $collection->addAttributeToSelect($attributes) //选择属性
    ->addMinimalPrice()
    ->addFinalPrice()
    ->addTaxPercents()
    ->addAttributeToFilter('test_product', 1, 'left')  //属性过滤 具备该属性
    ->addStoreFilter();  //商店过滤

Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
 //对产品的状态进行可见性过滤 Disable,EnableMage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($collection);  //visibility过滤 Catalog,Search,Not Visible$this->_productCollection = $collection;

 

3.

protected function _prepareLayout()  //面包屑
{
    if ($breadcrumbsBlock = $this->getLayout()->getBlock('breadcrumbs')) {
        $breadcrumbsBlock->addCrumb('home', array(
            'label'=>Mage::helper('catalog')->__('Home'),
            'title'=>Mage::helper('catalog')->__('Go to Home Page'),
            'link'=>Mage::getBaseUrl()
        ));
    }

    parent::_prepareLayout();
}

 

4.

protected function _beforeToHtml()
{
 parent::_beforeToHtml();
 $toolbar = $this->getToolbarBlock();   //工具条
 $toolbar->removeOrderFromAvailableOrders('position'); //移除可用的排序
 return $this;
}

 

5. 设定使用的模板

$this->setTemplate('catalog/product/edit.phtml'); //设置模板

 

6. 后台修改加入后台的块内容

$this->_addContent($this->getLayout()->createBlock('test/adminhtml_catalog_product_edit')); //实体的 不能是布尔的

 

7.图片的在php文件调用

<img src="<?php echo $this->getSkinUrl('images/tweeticon.jpg');?>"/>

 

8. 得到当前的store的RootCategoryId

$this->setCategoryId(Mage::app()->getStore()->getRootCategoryId());

 

9. 得到catelog

$category = Mage::getModel('catalog/category')->load($this->getCategoryId());

 

10.

$collection = Mage::getResourceModel('catalog/product_collection')
->setStoreId($this->getStoreId())
->addCategoryFilter($this);
