Magento-将自定义属性添加到订单并将此属性添加到集合过滤器

Question

I follow the method mentioned in this link Magento - Add custom attribute to order like below <global> ... <fieldsets> <sales_convert_quote> <your_special_attribute> <to_order>*</to_order> </your_special_attribute> <sales_convert_quote> </fieldsets> ... </global> to add new custom attribute to order and which is working fine. But the problem I am facing right now is when I use this attribute in collection filtering then it's not working for the below code..

$orders = Mage::getResourceModel('sales/order_collection')->addFieldToSelect('*')->addAttributeToFilter("your_special_attribute", array("finset"=>'2'))->setOrder('created_at', 'desc');

Answer 1

Adding custom attribute to order involves several steps. First you have to add a text field to the billing.phtml file. Then save the field in Quote and Order tables and write some event observers to capture quote save, and load events in config.xml file. The 3rd step is to display the field in My Account -> View Order. Next we need to show our custom field in Admin -> Order -> View Order page. Every step involves some coding modifications in certain files.

If you can specify which step are you facing problem with so that I highlight the files and the changes you need to make there.
