[TYPO3-mvc] Create multiple objects with one form using fluid

["Søren Andersen"]

Hi Henjo,

Sounds great that you have accomplished this on several occassions.

I worked a bit on this problem today, but I have no code to show yet.
Still trying to understand the correct approach conceptually.

What I want is to build a form like this:
Amount of type1: <input1> [+]
Amount of type2: <input2> [+]
Amount of type3: <input3> [+]

Each line should be made into a model of type Registration.

Ideally the user should be able to click the plus sign, to add another
line of the type, if that is necessary.

What I did today was to create a new model called AllowedTypes, which I
populate with the types the user can register on.

I can iterate and output a list of types, but have no idea how to
structure the form in fluid. One of my issues is, if I have 3 types, I
somehow need to distinguish these from each other. Normally I would do
something like tx_myplugin_pi1[registration][1][type] and put it in a
hidden input, and a corresponding text input for quantity.

Of course I can iterate the request in the controller, but if there's a
better way to do it I would love to know.

Henjo, you wouldn't happen to have some public code, where you create
multiple objects from one form?

Sincerely,
Søren Andersen
