I'm seeking some friendly guidance on the following:
On the shopping cart page, I'd like to include a text input area for the customer to enter a PO number or their own order description (ie: PO number or Project Name). It can show above the coupon code or somewhere else - that I can sort out myself.
I already know that I can use input text fields on individual products themselves (in fact, I'm already using those for other purposes), but if someone is ordering a whole bunch of things it's redundant to have the customer input the same PO number on each and every product added to the cart. This is why I'd like for them to just enter it on the shopping cart page itself. After they input the PO number and generate the order, I will have it displayed next to the order ID in the order history.
So far, the only cheat workaround I can think of is for me to first create "PO #" as a text option in the Catalog>Options section on the cart page and then put that in a div class in the cart page somewhere after the cart products listed, but then how do I call it on the order history page in the order_list.tpl file? I'll most likely replace the customer name to show PO instead. I'm not picky about placement, just knowing the line of code that would be needed to call it for it.
Thank you for any assistance that can be offered
