    Comment on it

    In magento sometimes we are required to change the attribute values of the products. 
    To do so we can work upon the event catalog_product_load_after.

    Lets see how we can do it:

    1. Create a module with namespace as Custom and module as ProductInfo.

    2. Then Create a file config.xml in etc folder in our module.

    3. Afterwards create a file Observer.php in Model folder.


    Now, in our config.xml file at the path Custom/ProductInfo/etc/config.xml lest change the product name for the same write the below code in it :


    <?xml version="1.0"?>


    In the above code we have defined our module with the version 0.1.0 and 
    then in global we have called our Observer at the event catalog_product_load_after 

    Now in our Observer at the path Custom/ProductInfo/Model/Observer.php write the below code:


    class Custom_ProductInfo_Model_Observer {
    public function ProductInfo($observer) {
        $product = $observer->getProduct();
        $product = $observer->getData('product');
        $product->setName($product->getName().' New Name !');


    In the above code we are loading the product first and then with the setName() magento method we have set up the new name as " New Name ! ". That's it we are done.
    In the same way we can change any attribute value of products.
