隐藏Magento中按列表排序的产品中的属性

Question

Is there a way to only show attributes in the Sort By list if there are products with that attribute on the page? My catalog has many different attributes but only one or two may apply to each product.

ie if I have attributes height, weight, color and I am looking at a page of t-shirts, I want to not sort by height or weight as these are irrelevent. On another page I might be listing boxes, so height and weight then do become relevent and should be added to the sort by list.

In Manage attributes, set " Use In Layered Navigation " as Filterable(with results) instead of Filterable(no results) to those attributes which you don't want to show when that attribute value doesn't exist on products

After performing the above solution. in Toolbar.phtml (or whereever if your extending),do the following,

 <?php
$orders=$this->getAvailableOrders();
$new_orders[]=array();
echo "<pre>";
print_r($orders);

$layer = Mage::getModel("catalog/layer");
$category=Mage::getModel('catalog/layer')->getCurrentCategory();
$category = Mage::getModel("catalog/category")->load($category->getId());
$layer->setCurrentCategory($category);
$attributes = $layer->getFilterableAttributes();


$attributesCodes[]=array();
foreach ($attributes as $attribute)
{

    $filterBlockName = 'catalog/layer_filter_attribute';
    $attributesCodes[]=$attribute->getAttributeCode();

    $result = Mage::app()->getLayout()->createBlock($filterBlockName)->setLayer($layer)->setAttributeModel($attribute)->init();

}
print_r($attributesCodes);

foreach($orders as $key_order=>$lbl_order){
    if(!in_array($key_order,$attributesCodes)) continue;
    $new_orders[]=$key_order;
}
print_r($new_orders);
?>
