Magento 常巧
1：获取session 
$session = Mage::getSingleton('customer/session');
2:Request对象
Mage::app()->getRequest()
3:调用Model对象
Mage::getModel('infinity/model');
4:获取当前时间
Mage::getModel('core/date')->date();
date("Y-m-d", Mage::getModel('core/date')->timestamp(time()));
5：session,cookie设置
5.1  Model：
Mage::getModel(‘core/cookie’);
Mage::getModel(‘core/session’);
5.2 Set Method:
Mage::getSingleton(‘core/cookie’)->set(‘name’,'value’);
Mage::getSingleton(‘core/session’)->set(‘name’,'value’);
5.3 Get method:
Mage::getSingleton(‘core/cookie’)->get(‘name’);
Mage::getSingleton(‘core/session’)->get(‘name’);
 
6:输出配置文件
 //header(‘Content-Type: text/xml’);        
header(‘Content-Type: text/plain’);        
echo $config = Mage::getConfig()
->loadModulesConfiguration(‘system.xml’)       
->getNode()
->asXML();         
exit;
7：Get URL for a Magento Category
Mage::getModel('catalog/category')->load(17)->getUrl();
8：build your URL with valid keys
Mage::helper("adminhtml")->getUrl("mymodule/adminhtml_mycontroller/myaction/",array("param1"=>1,"param2"=>2));
9：create key values
Mage::getSingleton('adminhtml/url')->getSecretKey("adminhtml_mycontroller","myaction");
10：disable security feature in the admin panel
admin panel -> System -> Configuration -> Admin section: “Add Secret key to Urls”.
11：后台模块跳转：
Mage::app()->getResponse()->setRedirect(Mage::helper('adminhtml')->getUrl("adminhtml/promo_quote/index"));
12：产品属性操作
$product = Mage::getModel('catalog/product')->getCollection()->getFirstItem();
foreach($product->getAttributes() as $att)
{
    $group_id   = $att->getData('attribute_group_id');
    $group      = Mage::getModel('eav/entity_attribute_group')->load($group_id);                
    var_dump($group);
}
 
$attrSetName = 'my_custom_attribute';
$attributeSetId = Mage::getModel('eav/entity_attribute_set')
->load($attrSetName, 'attribute_set_name')
->getAttributeSetId();
 
13：get a drop down lists options for a mulit-select attribute
$attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'attribute_id');
foreach ( $attribute->getSource()->getAllOptions(true, true) as $option){
$attributeArray[$option['value']] = $option['label'];
}
 
14：或取栏目图片
public function getImageUrl($category)         
{
return Mage::getModel('catalog/category')->load($category->getId())->getImageUrl(); 
}
 
public function getThumbnailUrl($category)
{
$image=Mage::getModel('catalog/category')->load($category->getId())->getThumbnail();
if ($image) { 
$url = Mage::getBaseUrl('media').'catalog/category/'.$image;         
} 
return $url;
}
15：产品缩略图
$_thumb = Mage::helper('catalog/image')->init($product, 'thumbnail')->resize(50, 50)->setWatermarkSize('30x10');
 
16：判断是否首页：$this->getIsHomePage()
   Mage::getSingleton('cms/page')->getIdentifier() == 'home'  &&
Mage::app()->getFrontController()->getRequest()->getRouteName() == 'cms' 
) 
 
17：
$cms_id = Mage::getSingleton('cms/page')->getIdentifier();
$cms_title = Mage::getSingleton('cms/page')->getTitle();
$cms_content = Mage::getSingleton('cms/page')->getContent();
18 :
$attributes = $_product->getAttributes();
 $themeColor = $attributes['theme_color']->getFrontend()->getValue($_product);
19：获取configurable产品simple product if($_product->getTypeId() == "configurable"):
$ids = $_product->getTypeInstance()->getUsedProductIds();
foreach ($ids as $id) :
 $simpleproduct = Mage::getModel('catalog/product')->load($id); 
$simpleproduct->getName()." - ".(int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($simpleproduct)->getQty();
 
$childProducts = Mage::getModel('catalog/product_type_configurable')->getUsedProducts(null, $product);
 
20:   get the attributes of Configurable Product.
$attributes = $product->getTypeInstance(true)->getConfigurableAttributes($product);
21：当前路径
$currentUrl = $this->helper('core/url')->getCurrentUrl();
22:通过资源配置方式创建目录
$installer = $this;
$installer->startSetup();
 
// make directory for font cache
try {
    $domPdfFontCacheDir = join(DS, array('lib', 'Symmetrics', 'dompdf', 'fonts'));
    $domPdfFontCacheDir = Mage::getBaseDir('var') . DS . $domPdfFontCacheDir;
    if (!file_exists($domPdfFontCacheDir)) {
        mkdir($domPdfFontCacheDir, 0777, true);
    }
} catch(Exception $e) {
    throw new Exception(
        'Directory ' . $domPdfFontCacheDir . ' is not writable or couldn\'t be '
        . 'created. Please do it manually.' . $e->getMessage()
    );
}
 
$installer->endSetup();
23：
<reference name="top.links">
            <block type="wishlist/links" name="wishlist_link"/>
            <action method="addLinkBlock"><blockName>wishlist_link</blockName></action>

        <beforeText></beforeText> 
        <afterText></afterText> 
    </action> 
</reference> 
24：在controllers 实现跳转
Mage::app()->getFrontController()
            ->getResponse()
            ->setRedirect('​​​http://your-url.com​​');25：获取当前站点货币符号
$storeId = (int) $this->getRequest()->getParam('store', 0);
$store=Mage::app()->getStore($storeId);
$currencyCode=$store->getBaseCurrency()->getCode()
 
$attribute = Mage::getModel('catalog/resource_eav_attribute')->load($attributeId);
                    $attributeData = $attribute->getData();
                    $frontEndLabel = $attributeData['frontend_label'];
 
                    $attributeOptions = $attribute->getSource()->getAllOptions();
 
26：获取产品属性集
$sets = Mage::getResourceModel('eav/entity_attribute_set_collection')
            ->setEntityTypeFilter(Mage::getModel('catalog/product')->getResource()->getTypeId())
            ->load()
            ->toOptionHash();
27:magento使用sql
 $resource = Mage::getSingleton('core/resource');
$read= $resource->getConnection('core_read');
$tempTable = $resource->getTableName('infinity_contacts');
$_storeid = Mage::app()->getStore()->getId();
$wheres = "`status`=1 AND ( FIND_IN_SET(0, `store_id`)>0 OR FIND_IN_SET($_storeid, `store_id`)>0 )";
 
$select = $read->select()
   ->from($tempTable, array('count(*) as num'))
   ->where($wheres);
28：设置meta信息
$template = Mage::getConfig()->getNode('global/page/layouts/'.Mage::getStoreConfig("featuredproducts/general/layout").'/template');
 
$this->loadLayout();                
 
$this->getLayout()->getBlock('root')->setTemplate($template);
$this->getLayout()->getBlock('head')->setTitle($this->__(Mage::getStoreConfig("featuredproducts/general/meta_title")));
$this->getLayout()->getBlock('head')->setDescription($this->__(Mage::getStoreConfig("featuredproducts/general/meta_description")));
$this->getLayout()->getBlock('head')->setKeywords($this->__(Mage::getStoreConfig("featuredproducts/general/meta_keywords")));
 
$this->renderLayout();
