为分类新增字段，并使用

bool类型的select框：可选是否的select原件

//决定是否是一个专区
$installer->addAttribute('catalog_category', 'homepage_special_category',  array(
		'group' => 'Display Settings',
		'type'     => 'int',
		'label'    => 'Homepage Special Category',
		'input'    => 'select',
		'source'   => 'eav/entity_attribute_source_boolean',
		'global'   => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
		'required' => false,
		'default'  => 1
));

 

varchar类型，text输入框

//决定推荐的商品的sku
$installer->addAttribute('catalog_category', 'hompage_featured_category_product_sku',  array(
		'group'    => 'Display Settings',
		'type'     => 'varchar',
		'label'    => 'Featured Product Sku',
		'input'    => 'text',
		'global'   => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
		'visible'           => true,
		'required'          => false,
		'user_defined'      => false,
		'input_renderer'=> 'adminhtml/catalog_category_helper_sortby_availables'
));

 

 在block内使用设置的自定义属性：

	/**
	 * 返回指定好的特殊推广分类的分类集合
	 * @return unknown
	 */
	function getSpecialCategory() {
		$collection = Mage::getModel('catalog/category')->getCollection()
		->addAttributeToSelect('homepage_special_category')
		->addAttributeToFilter('homepage_special_category', '1')
		->load();
		return $collection;
	}

 需要先getCollection,然后addAttributeToSelect指定需要筛选的属性，再用addAttributeToFilter执行筛选。
