Magento – How to hide empty attribute in any magento template

ce-1.8.1.0product-attribute

I want to hide the custom attribute in magento template. My magento version is 1.8.1

We have added custom attribute for our product like brand, dimension, product type etc. but sometimes we didn't add values in these attributes. magento shows No or N/A in product view page.

So, we want to hide attributes which are empty or no value in template.

A quick fix:

In app/[mypackage]/[mytheme]/template/catalog/product/view/attributes.phtml (or copy this file in your theme from base or default custom theme):

<?php foreach ($_additional as $_data):
// Add these 2 lines
$_test_data_value = trim($_data['value']);
if ((empty($_test_data_value) || in_array($_test_data_value, array(Mage::helper('catalog')->__('N/A'), Mage::helper('catalog')->__('No'))))) continue;?>

Below is not necessary to achieve what you've asked:

Those attributes are still loaded. To optimize this (if you have a big number of attributes in attributes sets) do:

public function getAdditionalData(array $excludeAttr = array())
{
    $data = array();
    $product = $this->getProduct();
    $attributes = $product->getAttributes();
    foreach ($attributes as $attribute) {
//            if ($attribute->getIsVisibleOnFront() && $attribute->getIsUserDefined() && !in_array($attribute->getAttributeCode(), $excludeAttr)) {
        if ($attribute->getIsVisibleOnFront() && !in_array($attribute->getAttributeCode(), $excludeAttr)) {

            // Fix:
            //$value = $attribute->getFrontend()->getValue($product);

            if (!$product->hasData($attribute->getAttributeCode())) {
                $value = Mage::helper('catalog')->__('N/A');
            } 
            // Fix:
            elseif ((string) ($value = $attribute->getFrontend()->getValue($product)) == '') {
                $value = Mage::helper('catalog')->__('No');
            } elseif ($attribute->getFrontendInput() == 'price' && is_string($value)) {
                $value = Mage::app()->getStore()->convertPrice($value, true);
            }

            if (is_string($value) && strlen($value)) {
                $data[$attribute->getAttributeCode()] = array(
                    'label' => $attribute->getStoreLabel(),
                    'value' => $value,
                    'code'  => $attribute->getAttributeCode()
                );
            }
        }
    }
    return $data;
}

Note the two // Fix: comments.

This modified function is from Mage_Catalog_Block_Product_View_Attributes. You need to copy the function above in your block class from your module. Your block class rewrites the core block class. Applying this will improve considerably product view page load on frontend.

If you don't know how to create a custom module in local dir than search a tutorial on how to create a Magento module and how to rewrite a core block class. Or try http://www.magentocommerce.com/magento-connect/ultimate-module-creator.html.

Magento2 Product Attribute – Fix Global Product Attribute Empty on Store View Level

Here is a quick fix.
you need to identify the attribute ids for all global attributes then delete all the values from the catalog_product_entity_* tables that have the attribute id one of those identified above and the store id field not zero.

DELETE FROM `catalog_product_entity_int` 
WHERE
   store_id <> 0 AND
   attribute_id IN (
           SELECT attribute_id 
           FROM catalog_eav_attribute 
           WHERE is_global = 1

   )

Do the same for the tables catalog_product_entity_varchar, catalog_product_entity_text, catalog_product_entity_datetime, catalog_product_entity_decimal.

Rebuild your indexes when your are done.

Note: The select from catalog_eav_attribute in the way I wrote it will give you attribute ids for the global category attributes also, but that's not important since in the product tables you don't have category attributes references.

Also, before trying this, backup your database in case I missed something.
