Simon,

Since you can only press one button to submit your form, you will only
get one button back - and it's index will always be zero. In the case
of a submit button, the brackets in 'name="Comment[]"' are superfluous -
you can't get back more than one button.

What you want is to get the id of the row (you do have a unique ID for
each row, right?) and use it in your name, i.e.

" ... name=\"comment[$id]\" ... "

Now you can get the $_POST['comment'] array and check your key to get
the id of the row.

No javascript or DOM needed.

Of course, there are other ways, but I like this one.
