insert custom item variable through xml in magento admin order detail Magento

Question

Hi I am developing a magento extension in which I need to show a product custom attribute in the magento order detail. I want to add it through xml without editing/ overwriting any core file .. For now i have edit the following file to show custom attribute value app/design/adminhtml/default/default/template/sales/items/column/name.phtml

but I know this is not the correct way. So please suggest me how can I insert it by blocks through xml. Below is the screen-shot link http://awesomescreenshot.com/0e42y3ac8d

Problem solved but with the help of java-script function.

To add your fields on order view page we need to do :

1. Add layout in your config file:

<adminhtml>
  <layout>
      <updates>
          <customattribute>
              <file>customattribute.xml</file>
          </customattribute>
      </updates>
  </layout>
</adminhtml>

1. Add design layout for adminhtml "app/design/adminhtml/default/default/layout/customattribute.xml"

<layout version="0.1.0">
  <adminhtml_sales_order_view>
      <reference name="order_items">
            <block type="customattribute/prototal"  name="order_item_extra_info" template="customattribute/productdesign.phtml"/>
      </reference>
  </adminhtml_sales_order_view>
</layout>

1. Add template File "app/design/adminhtml/default/default/template/customattribute/productdesign.phtml". Please do the format of file placing some sample code.

<?php 
$_item = $this->getItem();
$sku = $_item->getSku();
echo '<div style="display:none;"  id="id_order_item_'.$_item->getID().'"> <strong>'.$this->helper('sales')->__('Artwork ID').':</strong>'.$_item->getArtworkID().'</div>'; ?>
<script>
function codeAddress<?php echo $_item->getID(); ?>() {
          var html = document.getElementById('id_order_item_<?php echo $_item->getID(); ?>').innerHTML;
            var elem = document.getElementById('order_item_<?php echo $_item->getID(); ?>').children[0].innerHTML;
            document.getElementById('order_item_<?php echo $_item->getID(); ?>').children[0].innerHTML  = elem+html;
        }
codeAddress<?php echo $_item->getID(); ?>();
</script>

1. For getting Item in your template file you need define a block "CustomAttribute/Block/Adminhtml/Prototal.php"

class NameSpace_ModuleName_Block_Prototal extends Mage_Core_Block_Template { public function setItem(Varien_Object $item) { $this->setData('item', $item); return $this; }

  public function getItem() {
      return $this->_getData('item');
  }

}

Please comment someone found any issue or problem.

Doing changes in views/blocks is pretty much the same in frontend and adminhtml. You can create a theme/module and make your changes there instead of in the core files. Here is an official guide to do that.
