I think its easy but i don't found a way. In the product view.phtml ,I want to show the SKU. But only for simple Products. Is there any Way like this:
<div class="product-sku"> <h3> <?php echo $_helper->productAttribute($_product,$_product->getSku()->addAttributeToFilter('type_id', 'simple'), 'sku') ?> </h3> </div>
This way don't work.
