Question

Is there a single event that get fires whenever a product is loaded, either on its own or through as part of a collection?

I need to guarantee that no matter where or when a product model is loaded that i have access to that event in order to tack on an additional object. Be it frontend or admin.

Answer 1

Mage_Catalog_Model_Product::load() will result in the firing of catalog_product_load_before and catalog_product_load_after.

Mage_Catalog_Model_Resource_Product_Collection::load() will result in the firing of catalog_product_collection_load_before and catalog_product_collection_load_after.
