Multidimensional form input array.

Hewwo everyone, I'm having a problem with multidimensional form input arrays. Suppose there is a form set up like this: .. some hidden input fields .. <input type="hidden" name="Array[FileName]" value=something dynamic> .. .. then a loop (or section if you will, since I use smarty) .. <input type="text" name="Array[data][dynamic index][data_field]" value=something dynamic> The 'dynamic index' is the smarty loop index variable, which counts up from 0. (Now, besides from the fact that someone already pointed out to me that $Array might not be a good choice for naming this thing, I haven't before found any problems relating to that so I'm going to try and find another solution first) In my .php file I loop over the data as such: for ($i = 0; $i < count($Array['data']); $i++) { // do stuff with data fields in $Array['data'][$i] } But all the data fields are, not there, not set I guess. Is there any reason for this? Alexander.
