'visible_on_front' => false, 
'visible_in_advanced_search' => false, 
'unique' => false, 
'group' => 'General'
)); 
$installer->endSetup();

Then i want to get the author_name attribute value for each product in every category that is included in naigation menu of the site
i wrote the following query to get the attribute value:

    $categories = Mage::getModel('catalog/category')->getCollection()
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('include_in_menu', '1');
    foreach ($categories as $_category):
    if ($_category->getName() != 'Root Catalog'): 
     $category = Mage::getModel('catalog/category')->load($_category->getId());
     $products = $category->getProductCollection()
                       ->addCategoryFilter($category)
                       ->addAttributeToSelect('author_name')
                       ->setPageSize(9); 
         $author_names = array(); 
         foreach ($products as $_product):                             
        $author_names[] = $_product->getAttributeText('author_name');
         endforeach;
         print_r($author_names); 
    endif;
    endforeach; 

the array is not printing anything.

is there any thing wrong in my query.
