Want to tweak the Update Record function to add instead of replace. DWMX

[halcyonalt]

I have a reccomendation system instead of a rating system, and I'm using PHP and mySQL. The tutorial I found requires commands, and mySQL doesn't support that, so I thought that I could use a form and the update function that dreamweaver offers to add to the reccomendation count row.

Each time you press submit, it's supposed to add the value ("1") from a hidden field into the rec count row.

All I need to make it do is add one instead of replace what is already in the row. I'm not sure how to do this, as I am quite a newbie when it comes to coding in PHP. I don't want to screw anything up. Here is the code Dreamweaver spewed for my update record function, if you can help me modify it, I'd be much obliged:

[code]
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;   
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}

$editFormAction = $HTTP_SERVER_VARS['PHP_SELF'];
if (isset($HTTP_SERVER_VARS['QUERY_STRING'])) {
  $editFormAction .= "?" . $HTTP_SERVER_VARS['QUERY_STRING'];
}

if ((isset($HTTP_POST_VARS["MM_update"])) && ($HTTP_POST_VARS["MM_update"] == "recupdate")) {
  $updateSQL = sprintf("UPDATE Fanfiction SET `Rec Count`=%s WHERE ID=%s",
                      GetSQLValueString($HTTP_POST_VARS['newreccount'], "int"),
                      GetSQLValueString($HTTP_POST_VARS['ID'], "int"));

  mysql_select_db($database_altpanfics, $altpanfics);
  $Result1 = mysql_query($updateSQL, $altpanfics) or die(mysql_error());

  $updateGoTo = "justRated.php";
  if (isset($HTTP_SERVER_VARS['QUERY_STRING'])) {
    $updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
    $updateGoTo .= $HTTP_SERVER_VARS['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $updateGoTo));
}

$colname_showFic = "1";
if (isset($HTTP_GET_VARS['ficShowID'])) {
  $colname_showFic = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['ficShowID'] : addslashes($HTTP_GET_VARS['ficShowID']);
}
mysql_select_db($database_altpanfics, $altpanfics);
$query_showFic = sprintf("SELECT * FROM Fanfiction WHERE ID = %s", $colname_showFic);
$showFic = mysql_query($query_showFic, $altpanfics) or die(mysql_error());
$row_showFic = mysql_fetch_assoc($showFic);
$totalRows_showFic = mysql_num_rows($showFic);
[/code]

Anybody? Please?

I really can't figure out how to do this. :(
