[TYPO3-shop] Payment

[Leen Strijk]

Hello,

I have made a shop.
Everything is working

I managed to put a payment system in.
I did this by putting some formcode in the template. When finalizing 
there is a popupscreen where you can pay with credit card or ideal(dutch 
payment system)

The only problem I have is that the payment needs a unique number for 
processing.
The way to go is to use the ordernumber.
But the order number is not made at that time, because the order is not 
in the database yet.

I now made it so that the order is finalized and at this time you can 
click to pay. But this button is on the order overview page, and is not 
neat.

So my question is :
Is there a unique number(or string) I can use as identification to send 
to the payment gateway, just before finalizing the order.
So that the customers can pay first and then be redirected to the 
finalize page.


  The code:
<input type="hidden" name="BPE_Invoice" value="###ORDER_UID###" />

I need something else for ###ORDER_UID### like maybe a timestamp
