Hello everyone,

after 3 days of researching for a way to accomplish my need i thought its best to ask and hope to get an answer.

In this post

https://github.com/octobercms/october/issues/2772#issuecomment-296411282

it is exactly described what i am trying to do.

I have a repeater in my backend form and the data gets saved in the database as a json like that:

"topics": [

{
    "topic_title": "topic 1",
    "topic_description": "topic 1 descr",
},
{
    "topic_title": "topic 2",
    "topic_description": "topic 2 descr",
},

],

What i would like to achieve is that the repeater items get indexed like that:

"topics": [

{   
    "topic_id": "1",
    "topic_title": "topic 1",
    "topic_description": "topic 1 descr",
},
{
    "topic_id": "2",
    "topic_title": "topic 2",
    "topic_description": "topic 2 descr",
},

],

In another github post https://github.com/octobercms/october/issues/2451#issuecomment-259804208 it is stated that this could only be achieved by manipulating the array with

formBeforeSave()

But the information is already available in the code as

$indexCount: input type="hidden" name="___index_topics[]" value="2"

Can you please tell me how to get index/id into a repeater field so it gets stored inside the json array?
