We use this way to display attribute group names on the additional information tab on product page. Currently when a attribute got no data, the entire attribute will be hidden. I want to do the same for the attribute group name. So that if the attribute group got no attributes with data, it needs to be hidden.
This is our code:
<?php
$_helper = $this->helper('catalog/output');
$_product = $this->getProduct()
?>
<?php if($_additionalgroup = $this->getAdditionalData()): ?>
<div class="box-collateral box-additional">
<h2><?php echo $this->__('Additional Information') ?></h2>
<?php $i=0; foreach ($_additionalgroup as $_additional): $i++; ?>
<h3><?php echo $this->__( $_additional['title'] )?></h3>
<table class="data-table" id="product-attribute-specs-table-<?php echo $i?>">
<col width="25%" />
<col />
<tbody>
<?php foreach ($_additional['items'] as $_data): ?>
<?php $_attribute = $_product->getResource()->getAttribute($_data['code']);
if (!is_null($_product->getData($_attribute->getAttributeCode())) && ((string)$_attribute->getFrontend()->getValue($_product) != '')) { ?>
<tr>
<th class="label"><?php echo $this->htmlEscape($this->__($_data['label'])) ?></th>
<td class="data"><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
</tr>
<?php } ?>
<?php endforeach; ?>
</tbody>
</table>
<script type="text/javascript">decorateTable('product-attribute-specs-table-<?php echo $i?>')</script>
<?php endforeach; ?>
</div>
<?php endif;?>
How can I fix this?
