Hej alle,
Håber I kan hjælpe med dette..

Jeg har et popup vindue hvor jeg har følgende script.

<?php require_once('../Connections/database.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;
}
}

if ($_POST['knap'] == 'Ja') {
echo "ja";
  $deleteSQL = sprintf("DELETE FROM jobs WHERE id=%s",
                      GetSQLValueString($_GET['id'], "int"));

  mysql_select_db($database_Netkoncept, $Netkoncept);
  $Result1 = mysql_query($deleteSQL, $Netkoncept) or die(mysql_error()); ?>
  <script language=JavaScript>
  window.close();
  </script><?php
}

if ($_POST['knap'] == 'Nej') { echo "nej";?>
  <script language=JavaScript>
  window.close();
  </script>
  <?php
}

$colname_rsDelete = "-1";
if (isset($_GET['id'])) {
  $colname_rsDelete = $_GET['id'];
}
mysql_select_db($database_test, $test);
$query_rsDelete = sprintf("SELECT * FROM jobs WHERE id = %s",
                        GetSQLValueString($colname_rsDelete, "int"));
                       
$rsDelete = mysql_query($query_rsDelete, $test) or die(mysql_error());
$row_rsDelete = mysql_fetch_assoc($rsDelete);
$totalRows_rsDelete = mysql_num_rows($rsDelete);
?>
  <style type="text/css">
<!--
.style1 {
    color: #FF0000;
    font-weight: bold;
}
-->
  </style>
  <link href="../assets/styles.css" rel="stylesheet" type="text/css" />
  <form name="form1" method="post" action="">
  <table width="200" border="0">
    <tr>
      <td><p align="center"><span class="h1">Er du sikker p&aring; at du vil slette:</span><br />
            <br />
            <span class="style1"><?php echo $row_rsDelete['headline']; ?> </span></p>
        <p align="center">
          <input name="knap" value="Ja" type="image" src="../assets/images/ja.png">&nbsp;
          <input name="knap" value="Nej" type="image" src="../assets/images/nej.png">
        </p></td>
    </tr>
  </table>
  <p>&nbsp;</p>
  </form>
<?php
mysql_free_result($rsDelete);
?>

Det virker i Firefox og Safari, men ikke Explore..
Nogen der kan gennemskue om der er en fejl som Explore absolut skal falde over
