Dynamic Comment Boxes: Hard to get correct $_POST

this code is in a while loop which dynamically creates a comment box for each thread in a type of forum; multiple threads are seen on the same page with multiple comment boxes.

[code=html]<textarea wrap=”soft” name=”<?=$rowzero?>” rows=”2″ cols=”25″></textarea>
<input type=”submit” name=”submit” value=”OK” />[/code]

$rowzero is an integer and associates the comment box to the post, and is gathered from the DB when the thread loads. When user clicks submit, then $_POST[$rowzero] should contain the text for the comment, but my problem is after a submit $rowzero is NULL. I tried putting the code that adds the comment to the DB AFTER $rowzero is accessed from the DB, which means I have to reload the page to see the comment updated. This is unacceptable. I need a way to realize which $_POST[##] I should be accessing for the comment.

Any suggestions?

Thanks in advance,
Tyler

PS> To clarify, when user hits submit $_POST makes an associative array of all the comment boxes on the page, most of which contain nothing. I was thinking of some type of loop to see which one had something, but my $rowzero is int(11) so that could be prohibitive, and POST is associative.
