Stay on onepage checkout page after 'Place Order' button pressed.
Hi. I am going to re-phrase a question I asked a few days ago. Is there a way to stay on the onepage Checkout when the 'Place Order' button is pressed? Currently I am calling a controller at this point, and get re-directed to the controller page. Should I be using a controller or another method if I want to perform some tasks but stay in the final onepage Checkout page? Thanks for any pointers in advance as I am new to Magento.
