It'll make your life easier. echo "<input type=\"text\" name=\"userId[$i]\" maxlength=\"5\"/><br />"); You can still reference the element in Javascript, just "by name" or whatever you call it. form.element['userId[1]'] (or something like that). You show a Javascript validation. Remember that this is easily bypassed so you also need to validate the numbers on the PHP side. <?php foreach($_POST['inputId'] as $id) { if(!is_numeric($id)) { echo "$id is invalid!"; } } ?> ---John Holmes...
