How to submit dynamic form with multiple levels of tabs and modules in PHP?

I have a registration form of residential complex with multiple levels, as you can see. And I'm stuck.

Note: from the screenshot you can see that 1st level of tabs (houses) can have any number of tabs and so is 2nd one (porches).

How to generate all that tricky staff, when onclick on tab, and mess with ids? I'm just really confused... How can I submit all that information into my MySQL DB from this form which generates dynamically?

Please, explain, show or code to help me in that complicated construction :c

Thank you!
