I don't know how you set up you logic on the client.
But from the looks of it you are not experienced in Javascript. It looks
very messy to me. :-(

Anyway, if you want to solve it serverside you can also try something
like this:
Assuming you have the folowwing structure:
$_POST['product_data'][..productid..][..productvariant..]

and you post something that arrives as:
$_POST['product_data'][123][987]['prezzo0']

$allKeys = array_keys($_POST['product_data'])
Now $allKeys will contains an array with 123.

If you post multiple productdata, that arrive like this:
$_POST['product_data'][123][123]['prezzo0']
$_POST['product_data'][22][165]['prezzo0']

Then $allKeys will contains an array with 123 AND 22.

Read more here:
http://nl2.php.net/manual/en/function.array-keys.php

Alternatively you can use foreach as here under:
foreach ($_POST['product_data'] as $aProductKey => $productInfo){
// $aProductKey now 123
}

You can do the same productinfo.

Hope that helps, but I would advice you to make better better use of
Javascript, because that is an easier approach. (And stay away from JQuery)

Good luck.
