Magento duplicate product with leaving out specific attributes

Question

I would like to be able to Duplicate a product using the default Magento Duplicate option, but leave out several attributes that need to be blank so that the user is forced to change them before saving. Example: after duplicating, my attribute Table-Depth is always different, and if not left blank could go un-noticed for the user to input proper new value.

Answer 1

You could create an observer for catalog_model_product_duplicate

Take a look at Change Magento default status for duplicated products

Then in your observer, set the fields value to NULL, '' or whatever their default value are.

eg.

class MagePal_ResetDuplicateProductValues_Model_Observer 
{

   public function productDuplicate(Varien_Event_Observer  $observer)
   {
      $newProduct = $observer->getEvent()->getNewProduct();
      $newProduct->setTableDepth('');
      ...
