[TYPO3-dev] Trouble using hooks

[Schani]

Hello Masi,

for example: In a extension like tt_news, create a news article and 
instantly also create a sysfolder for more subpages on the pagetree.
I need the Sysfolder(s) for many subpages of a record of my extension.

2nd example. I create a Product in my extension with basic infos like 
Produktname, Hersteller, Preis. But now i need more Pages in pagetree 
for information to this Produkt. But like to use the flexibility of TV 
to design a subpage. Some Producs have only one Subpage. Other Products 
have 27 Subpages. For this subpages i also want to use a menue
. No its the best to put this Produkt Subpages in a Sysfolder:

- home
- productlist
   |- product database (sysfolder)
- Produkt-subpages (sysfolder)
   |- Product1 (sysfolder)
      |- technical details
      |- configuration
      |- support
   |- Product2 (sysfolder)
      | - configuration
   |- ...


The Products are so different that i can not include all infos in one 
database. And its also in one database not possible to use TV for the 
detail view.

Yes, each new record should create a new sysfolder. Thats what i want.
