Add custom block/div Order Details page

Question

I have a custom module, whose content I need to show on Order Details page.

Not under any new tab or something but just above the "Order Totals" div.

How do I accomplish this without modifying any core files?

Answer 1

Add layout file in yourmagento/app/design/adminhtml/default/default/layout/yourmodule.xml

Add below content in that:

  <adminhtml_sales_order_view>
    <reference name="order_tab_info">
        <action method="setTemplate">
            <template>yourmodule/sales/order/view/tab/info.phtml</template>
        </action> 
<!-- Add your block to display in above order total block -->
    </reference>
</adminhtml_sales_order_view>

Copy default info.phtml file from app/design/adminhtml/default/default/template/sales/order/view/tab/info.phtml to app/design/adminhtml/default/default/template/yourmodule/sales/order/view/tab/info.phtml

Add your content in info.phtml as per your need above order total div.

Answer 2

To add the contents to the Order Information section (First block on the admin order page), inside app/design/adminhtml/default/default/layout/yourmodule.xml add below:

<adminhtml_sales_order_view>
    <reference name="order_info">
        <action method="setTemplate">
            <template>yourmodule/sales/order/view/info.phtml</template>
        </action> 
    </reference>
</adminhtml_sales_order_view>

Now you can copy:

app/design/adminhtml/default/default/template/sales/order/view/info.phtml

to

app/design/adminhtml/default/default/template/yourmodule/sales/order/view/info.phtml

Now you can add your stuff to the info.phtml inside your module, without change the core files.
