Group form elements

Question

I have been looking for this through the net but I have not found the right solution for my problem. I am working with the stock market. I have a form in my website, and a part of it needs to be repeated for some symbols.

Let's say I need to set some properties for each symbol, so I have some inputs that are the same for every symbol. What I would like to do is define the fields in some way that once I am processing them in my PHP script, I can access to the data doing something like this:

$_POST["symbol"]["field"]

I have 3 symbols now, but in the future I will have much more, so I would like to process the whole thing with a loop instead of having to access every single field manually (e.g.: $_POST["symbol-field"]).

The part of the code that it is repeated

<select multiple="multiple" name="selectAverageIBM[]">
    <option>SMA10</option>
    <option>SMA20</option>
    <option>EMA10</option>
    <option>EMA20</option>
</select>

So I already have an array for the field since it is a multiple select.

I have seen there is a tag called FIELDSET that could work, but I don't get it to work.

Thank you very much.

You can set the field names to `symbol[]`, which will cause their values to be handled as an array in PHP. Unfortunately, this method does not allow for further identification. The array will be a 0-indexed array, so you only have numeric array keys. — BenM, Aug 21 '13 at 10:41
I have just added more code in the main message. I can not really use the symbol[] that you suggest BenM, since I already have it as an array because it is a multiple select. — user2417250, Aug 21 '13 at 10:47

I can not really use this since the inputs are multiple selects and I have already named them as arrays. – user2417250 Aug 21 '13 at 10:49
have you used while if why not use name="field[][]" – Sonu Sindhu Aug 21 '13 at 10:53
make it a multidimensional one! `` – giorgio Aug 21 '13 at 10:53
so use foreach for somename[somekey] inside parent foreach – Sonu Sindhu Aug 21 '13 at 10:56
That's it! That works perfectly for what I need. Thank you very much giorgio and sonusindhu – user2417250 Aug 21 '13 at 11:35
