get an array of all a products attributes in magento

I cannot figure this out!

I am trying to get a list of a products attributes into an array on the list.phtml page. I have tried everything. I have seen a lot of solutions that use

$attributes = $product->getAttributes();

but I cannot get this to work, it just brings up a blank page. Any help would be greatly appreciated, I have spent hours and hours on this so far…

I am using Magento version 1.4.2.0

UPDATE: Here is exactly what I am trying to do:

$neededAttributes = Mage::helper('mymodule')->getNeededAttributes();
$attributes = $product->getAttributes();
foreach ($attributes as $attribute) {
   if(in_array($attribute->getAttributeCode(), $neededAttributes)) { 
      $attributename = $attribute->getAttributeCode();
  echo $attributename;
   }
 }

this is in the file gallery.phtml in design/adminhtml/default/default/catalog/product/helper/

For some reason, I cannot get the getAttributeCode function to return anything.

  1. I’m guessing you need a list of only visible values. I say “values” because attributes are not the actual values, they are descriptors. The following is the salient parts from Mage_Mage_Catalog_Block_Product_View_Attributes:

    $attributes = $product->getAttributes();
    foreach ($attributes as $attribute) {
        if ($attribute->getIsVisibleOnFront()) {
            $value = $attribute->getFrontend()->getValue($product);
            // do something with $value here
        }
    }
    

    You don’t really need to duplicate this though since you can alter/use the template catalog/product/view/attributes.phtml which is already declared on the product view page as attributes block.

  2. According to your question, you should be using Mage::getResourceModel('catalog/product_attribute_collection') instead:

    $productAttrs = Mage::getResourceModel('catalog/product_attribute_collection');
    
    foreach ($productAttrs as $productAttr) { /** @var Mage_Catalog_Model_Resource_Eav_Attribute $productAttr */
        var_dump($productAttr->getAttributeCode());
    }
    

    You don’t always have attributes in the _data (getData()) storage and you don’t always need to load a product to get its attributes.

  3. It’s rather easy and gives you an array of available product attribute names

    $product = Mage::getModel('catalog/product')->load('product_id');
    $attributeNames = array_keys($product->getData());
    print_r($attributeNames);
    

    If you need a attribute object collection you can call

    $product->getAttributes();
    

    If you need a product collection and after that you can perform the previously mentioned ways on each collection member

    Mage::getModel('catalog/product')->getCollection();
