in magento invoice order items i want to show product price, qty and subtotal. I changed the order items in the below file path /app/design/frontend/base/default/template/email/order/invoice/items.php But no change. Anyone help me where and how to change the order items?
First you should not change the magento core files. The best ways to override a template is to add a custom package with a custom theme. This theme has the base/default theme as parent theme(you can define this in the theme.xml).
Once you added your own Package, you can copy the template from base/default, insert it in your theme and then make your changes.
Of course your theme has to be applied in the magento backend.
Hope this helps.
