Php check all records in database then display results based on chosen record

Question

I have a form that is checking the database to see if a record exists .
If it does exist then it needs to perform one of two tasks, either subtract or multiple.
This part is working but the part that is not working is it is only checking the first record of the database and it should be checking all records as each record will give a different result
the sql is
mysql_select_db($database_lotties, $lotties);
$query_rsVoucher = "SELECT * FROM LOTTIE_vouchercode";
$rsVoucher = mysql_query($query_rsVoucher, $lotties) or die(mysql_error());
$row_rsVoucher = mysql_fetch_assoc($rsVoucher);
$totalRows_rsVoucher = mysql_num_rows($rsVoucher);
// then check
if (isset($_POST['vouchCode']) && $_POST['vouchCode'] == $row_rsVoucher['VCode']) {
  $mycode = $row_rsVoucher['VCode'];
  $spos = strpos($mycode, "f");
  if ($spos !== false) {
    $myvalue = substr($mycode, $spos+1);
    $myvalue = $XCart_sumTotal * $myvalue / 100;
  } else {
    $spos = strpos($mycode, "p");
    if ($spos !== false) {
      $myvalue = substr($mycode, $spos+1);
  $myTotal = $XCart_sumTotal - $myvalue;
  $_SESSION['vouchCode'] = $myvalue;
} else unset($_SESSION['vouchCode']);
the form is
<form action="<?php echo $editFormAction; ?>" method="post" name="form2" id="form2">
<input type="text" name="vouchCode" value="<?php echo @$_POST['vouchCode']; ?>" size="32" />
<input type="submit" value="update" />
</form>
then the results are displayed
<?php if (isset($myvalue)) { ?>
<?php echo DoFormatCurrency($myvalue, 2, ',', '.', '£ ', ''); ?>
<?php } ?>
i am getting really desperate with this so any help would be appreciated
thanks

jonathan, jonathan, jonathan,
Condolences to your deceased php developer. Was he the only professional php developer in the world? I don't think so! Enough with your excuses already. Find a professional php developer that is currecntly living then and stop looking for free professional work for your specific, profitable development requirements on a forum.
best,
