==============PHP code(part1)==============
function productlist($itemname,$itemquantity) {
    for($i=0;$i<count($itemname);$i++)
    {
        echo $itemname[$i] .",". $itemquantity[$i]."<br>";
    }
}
$message = productlist($itemname, $itemquantity);

Question: the coding can run with part 1 result, may i know how to pass part1 result into part2 and can send out successfully.

Answer 1

Readonly is a Bool value so you don't have to set it to anything. Not that you should trust data from the client. It can be easily over written.

Your server will have to be configured to send email. If it's not that's a different problem to work on.

<input name="itemquantity[]" type="text" value="3">

==============PHP code(part1)==============
$message = productlist($_POST['itemname'], $_POST['itemquantity']);

function productlist($itemname,$itemquantity) {
  $message = '';
  for($i=0;$i<count($itemname);$i++){
    $message .= $itemname[$i] .",". $itemquantity[$i]."<br>";
  }
  return $message;
}

$to = "abc@abc.com";
$subject = "Online order form";
mail($to, $subject, $message, $headers);
