I think its easy but i dontdon't found a way. In the product view.phtml I,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 dontdon't work.
