Hi guys,

Hopefully one of yol know the solution as it has been eluding me so far :).

When my from value is calculated (update button is pressed) I want the form to remember previously entered values for my list boxes (venue and ticketType). The code in red is where i need help or just someone to point me in the right direction.

 

 

<?php require_once('../Connections/connect.php'); ?> <?php

if (!function_exists("GetSQLValueString")) {

function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")

{

  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

 

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($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;

}

}
