Yes, its true, probably some kind of form-mail script will be more suitable for my needs. But not a mail script only, but a combination with a search script and cart script, plus use cookies(or Javascript) plus few html templates. I need that user can search in database, select items, then mail selected items to his address, plus copy to me.
There are no problem with search.
Example: mp3catalog (try search something)
I would just add 'add' link or check box(looks better) against each found item. User search for item, add item, preview order, then start search again, add new items.. Finally user press 'Checkout', its redirect on 'Order' page where user fills in his data and send order.
All looks elementary, I am just surprised, why it's almost impossible to find such simple and convenient script..
