Extend Sales Order Grid to show Printed Yes/No

Question

I'm trying to add a new column to the sales order grid that shows whether an order has previously had its invoice printed out - I've searched everywhere and can't seem to find a solution.

We use custom grids at the moment and have several custom columns

TIA

Answer 1

That can be a bit difficult to track. How are you printing invoices? How do you track whether your customer print an invoice you send attached in an email?

Let say you have a way to track this, I would create a custom order attribute to flag orders and show it in a custom column in grid, look at this for example: Mage_Sales_Controller_Abstract::printAction() to a place where set the attribute to true.

You can have your custom controller to handle your attribute flag and then redirect to Mage_Sales_Controller_Abstract::printAction()

For more examples on printActions look in admin controllers at: app/code/core/Mage/Adminhtml/controllers/Sales/Order/

If you are using print functionality from backend then you can add the flag attribute and set the attribute by listening one of the events controller post/pre dispatch. Then show attribute in grid.

This is a good resource on how to add custom attributes to orders
