Hide Attributes which have no value in Magento

Open attribute.phtml, which is located in app/design/frontend/[your package]/[your theme]/template/catalog/product/view folder, and find code like this:

 

<?php foreach ($_additional as $_data): ?>
<tr>
<th><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
<td><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
</tr>
<?php endforeach; ?>


Now replace this by:



<?php foreach ($_additional as $_data): ?>
<?php $_attribute = $_product->getResource()->getAttribute($_data['code']);
if (!is_null($_product->getData($_attribute->getAttributeCode())) && ((string)$_attribute->getFrontend()->getValue($_product) != ")) { ?>
<tr>
<th><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
<td><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
</tr>
<?php } ?>
<?php endforeach; ?>
