Question

I am trying to edit the reports generated from here, example.com/index.php/admin/sales_order/index/. I need to add a new report to the dropdown on the right.

I traced this page to it’s controller through the url and dumped the class.
app/code/core/Mage/Adminhtml/controllers/Sales/OrderController.php indexAction() and got this class Ext4mage_Html2pdf_Sales_OrderController so I know it’s being overridden by a module. In this case the Ext4mage Html2pdf module.

This controller just overwrites the pdf methods using,

require_once BP.'/app/code/core/Mage/Adminhtml/controllers/Sales/OrderController.php';
class Ext4mage_Html2pdf_Sales_OrderController extends Mage_Adminhtml_Sales_OrderController{
//etc }

So I’ve created my new module in local, hoping to overwrite this as it’s in community.
app/code/local/Daves/OrderModule/controllers/Sales/OrderController.php and placed in the following.

require_once 'Mage'.DS.'Adminhtml'.DS.'controllers'.DS.'Sales'.DS.'OrderController.php';
require_once BP.'/app/code/community/Ext4mage/Html2pdf/controllers/Sales/OrderController.php';

class Daves_OrderModule_Sales_OrderController extends Ext4mage_Html2pdf_Sales_OrderController{

    public function indexAction(){

        die();

        return parent::indexAction();
    }

}

My expected functionality would be that upon reloading the Sales/Order page in admin, I’d get a blank page, and I don’t. Which would mean that my controller isn’t being loaded.

My IDE is showing that the classes are being extended, and putting a die() into an indexAction() method in the Ext4mage_Html2pdf controller works as expected. It’s just missing out my controller for some reason.

Trying to hit the controller directly in a browser using example.com/admin/daves_ordermodule/sales_order/index also throws a 404.

Should I be trying to overwrite the blocks instead?

I’ve not created any funky <rewrite> update handles in my config, mainly because I’m not sure if I need them, or where they would go. As I know Magento takes from Zend in it’s horrific use of xml, I’ll paste in my configs here.

Assuming you have no frontend controllers, adjust your config as follows:

<!-- How to get to the module from the browser -->
<admin>
    <routers>
        <adminhtml> <!-- My unique class group -->
            <args>
                <modules>
                    <Daves_Om before="Ext4mage_Html2pdf">Daves_OrderModule</Daves_Om>
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>

What this does is add another controllers directory under the Mage_Adminhtml module’s frontname. The value from <Daves_Om> is essentially mapped to the text node + “controllers”, so app/code/(configured codepool)/Daves/OrderModule/controllers/ – and then the typical route matching applies.
