Loop multiple field

Hello. I want update multiple fields.
I think that is wrong the Data Provider of Loop Function.
In fact, if I insert one of these field ({data:nome} or {data:formato} ), it work correctly.
​
But what is the array to update both fields.
I tried {data:} and {data:model_name_read_data}, unsuccessfully.
​
Thank you for your support.
​

What does your debug show. Use {debug:} at the end of the event.

This is with {data:} in loop function

Put them both in an array format. So change the name to something like model[{var:table_list_name.row.model.id}][nome] so you're given an array of values on submit.

I'm very sorry, Put them both in an array format?
How can I do?

Change the name of the field to the thing I said

so:
- in text field of formato changed Name with Prefor[{var:prefor_list.row.Prefor.id}][formato], in text field nome with name Prefor[{var:prefor_list.row.Prefor.id}][nome],
In data provider loop I maintain {data:}

I think to be near to solution.
view formato - name model[{var:table_list_name.row.model.id}][formato]
view nome - name model[{var:table_list_name.row.model.id}][nome]
function -loop - data provider {data:model}
function - save data - data provider {data:} - data override nome - {var:save_pre_for_loop.row} - on update and formato - {var:save_pre_for_loop.row} - on update
​
This is debug, suggestion?

Replace "table_list_name" with the name of your table list, replace "model" with the name of your model.

Done! I used example text, but in my work it's correctly complied (Prefor[{var:prefor_list.row.Prefor.id}][formato] - Prefor[{var:prefor_list.row.Prefor.id}][nome] - {data:Prefor})
