[TYPO3-shop] additional form in order process

[Christian Tauscher]

Hi dear developers!

I'd like to have an additional form while the order-process. i hope this
diagramm helps:


          Go shopping, choose articles from shop
             |
          Goto Order
	  Enter your name, delivera etc.
             |
          ** CONDITION:
          ** IF some special Article (uid, category?) is in basket
          ** ask more questeions e.g. age, serial for update,
             |
          Go on with the usual Oder Process
          (agree to everything, payment, finalize)


So, depending on a special Article, defined by uid or category, some
more details are asked.
This details are included into the E-mails the shop sends to the
shop-owner and/or the customer.


Does anyone already have a solution for this? AFAIK tt_products does not
offer this by default.
I am studying the source actualy, but It seems to me there is no
suitable hook for this. Idea: Maybe the payment could be abused for
this....???


I would be glad if you can give me a hint to the right direction.

Thank you,

Christian.
