Create Post In Discussion Tab On The Order Detail Page Via Form

Hi!



I have a online Q&A service and have made a form with a textarea field and two-three input fields and at the bottom there’s a radio button group with two options (representing two different products).



Depending on the product they have chosen from the radio button group, the chosen product is remotely added to the cart via a URL redirect when they hit submit and the customer goes directly to checkout.



However I want the form values (i.e. the text field values from the form) to follow the order and create a new post under the discussion tab found in the order details page with its contents if they continue to payment. I answer the customer using the same discussion tab so it would be neat if their question was already there.



Any idea how I can do that and if it is possible?



Thanks! :-)
