I'd like to use the Magento's print feature in my module to have the invoice pdf of a programmatically created order. For that I'd like to get the url that Magento back end uses to print the invoice. eg : http://localhost/magento1/index.php/admin/sales_order_invoice/print/invoice_id/104/key/eaf550ef39cc92e93b562994019fde14/ enter image description here

My question is how can I get that key to build the url that retrieves the invoice pdf ?


just write below code


and it will autometically add key

  • This generate the following link : http://localhost/magento1/index.php/sales_order_invoice/print/invoice_id/key/1c762f48f0b4a305a038d599b84bda83/. This does not add the invoice_id (104 in our example). I don't know why it does not add the invoice_id ... – androniennn Dec 26 '16 at 11:25

    @androniennn I am not sure but you can try this Mage::helper("sales")->getUrl("adminhtml/sales_order_invoice/print/invoice_id/104/"); – Murtuza Zabuawala Dec 27 '16 at 5:07
