So first of all, I have a confession, I used Dreamweaver to take care of all my database work. Pheww. Now that I got that of my chest, I am having problems, not only with my lack of experience working with databases, but with my script also. I need to insert multiple checkbox values into my database into the same cell. So I have searched around and I thought I had found a fairly good approach, but with Dw's hodgepodge of overcomplicated mess, I am finding problems integrating it. The error I am getting post submission is "Warning: mysql_real_escape_string() expects parameter 1 to be string, array given in C:\wamp\www\gov\ballot.php on line 10

Column 'involvement' cannot be null" So if you would, could you debug my script and give me some instruction along to way so that I can learn a little something too? Here is my script:

 

<?php require_once('Connections/ballot.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($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;
}
}


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

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "Ballot")) {
  $insertSQL = sprintf("INSERT INTO votes (`first`, `last`, gender, grade, involvement, schedule, party, `time`) VALUES (%s, %s, %s, %s, %s, %s, %s, %s)",
                       GetSQLValueString($_POST['first'], "text"),
                       GetSQLValueString($_POST['last'], "text"),
                       GetSQLValueString($_POST['gender'], "text"),
                       GetSQLValueString($_POST['grade'], "text"),
                       GetSQLValueString($_POST['involvement'], "text"),
                       GetSQLValueString($_POST['schedule'], "text"),
                       GetSQLValueString($_POST['party'], "text"),
                       GetSQLValueString($_POST['time'], "text"));

  mysql_select_db($database_ballot, $ballot);
  $Result1 = mysql_query($insertSQL, $ballot) or die(mysql_error());

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

mysql_select_db($database_ballot, $ballot);
$query_Recordset1 = "SELECT * FROM votes";
$Recordset1 = mysql_query($query_Recordset1, $ballot) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
