I have a form with a multi-level tree of one to many relationships. For example:

Match -> Phase 1 -> Phase Property 1
      -> Phase 1 -> Phase Property 2

      -> Phase 2 -> Phase Property 1
      -> Phase 2 -> Phase Property 2
      -> Phase 2 -> Phase Property 3

      -> Phase 3 -> Phase Property 1
      -> Phase 3 -> Phase Property 2

So, on the front-end I am able to add many phases to a match and many phase properties to a phase.

In the PHP back-end, I would like to be able to represent this data in a multi-dimensional array, so that I can loop through all the phases and then loop through each phase’s properties. Ideally, I would like to stay away from managing Ids/names through JavaScript.

I know I can receive an array in PHP using something like this:

<input type="text" name="phases[]" />

But, how do I continue this pattern for the properties? Can I do something like:

<input type="text" name="phaseProperties[][]" />

and then somehow “link” each property to the right phase?

    If the input fields appear on a static page, then you should already know how much input fields you are going to make on the server side. So why is using fields like:

    <input type="text" name="phaseProperties[0][]" />
<input type="text" name="phaseProperties[0][]" />
<input type="text" name="phaseProperties[1][]" />

    such a bad thing? If the fields are being dynamically (client-side) generated then there shouldn’t be a problem naming them dynamically aswell. You seem to be constraining yourself too much for no apparent reason.
