How can i get loaded product data in custom module

Question

I try to get the product data in my module. I tried to find a solution without

Mage::getModel('catalog/product')->load($id)

My module is embedded in the product detail site. So, when I load the site the data of this product is already loaded. How and where can I access this data?

• Should I use any observers?

• Is it stored in session?

May be some body can help me :)

Answer 1

i want to answer my question with my solution:

i did it in this way:

1. add session Object from Magento in the modul template
2. add to the 'core/session' new value from registry('curent_product')
3. the controller which is calling with ajax can now access the product id or ather stuff over the session

here is the code:

phtml - File

$_product = Mage::registry('current_product');
$zwSession = Mage::getSingleton('core/session', array('name'=>'frontend'));
$zwSession->setProductId($_product->getData('entity_id'));

here the controller:

 $zwProductId = Mage::getSingleton('core/session')->getProductId();
 $zwProduct = Mage::getModel('catalog/product')->load($zwProductId);
 $zwProduct->getData('od3_json');

So it works know like i need.

But is it nice? ;)

If you're on the product page you can access the current product using:

$_product = Mage::registry('current_product');

Add your custom module template file in local Xml file with handle such as

< reference name="product.info"> < /reference>

then Mage::register() method work.
