@AnthonySterling that works, please when i try to update, it dosent, can you help look at this code
(the value in the POST array, is the updated values on the form)
Array ( [item] => Array ( [0] => Array ( [Pquantity] => 5 [Pidno] => 2 ) [1] => Array ( [Pquantity] => 6 [Pidno] => 1 ) ) )

//print_r($_POST);
if(array_key_exists('item', $_POST)){
    //$items = $_POST['item'];
  //foreach($_POST['item'] as $item){
    //echo $item['Pquantity'] . ", ";
    //echo $item['Pidno'] . ", ";
    //}
    //Loop through $_POST items, updating the database for each item
    foreach ($_POST['item'] as $item) {
        $Pquantity = intval($item[0]);
        $Pidno = intval($item[1]);
        $queryreg = mysql_query("
            UPDATE repplac
                 SET Pquantity = {$Pquantity}
                 WHERE
                       Pidno = {$Pidno}
                 AND
                       username = '{$_SESSION['username']}'
        "

You’re using numeric indicies for the $item array, you should be using Pquantity, Pidno etc; the numeric ones do not exist.

its updating now, i used

//print_r($_POST);
if(array_key_exists('item', $_POST)){
   // $items = $_POST['item'];
  //foreach($_POST['item'] as $item){
    //echo $item['Pquantity'] . ", ";
    //echo $item['Pidno'] . ", ";
   // }
    //Loop through $_POST items, updating the database for each item
    foreach ($_POST['item'] as $item) {
        $Pquantity = intval($item['Pquantity']);
        $Pidno = ($item['Pidno']);
        //echo $Pquantity . ", ";
   		//echo $Pidno . ", ";
        $queryreg = mysql_query("
            UPDATE repplac
                 SET Pquantity = {$Pquantity}
                 WHERE
                       Pidno = {$Pidno}
                 AND
                       Uname = '{$_SESSION['username']}'
        ") or die(mysql_error());
