If I got it right your script works fine on local PC but does not work when on online server? But what does not work - inserting into the database or redirection to another page?

If insertion does not work you have to make sure the connection to the database on the online server has been successfuly established. You are checking for errors already on line 9 but I will suggest you insert some debug code like this:

mysql_select_db($database_marketbase, $marketbase);
// *** DEBUG CODE 1
$res = mysql_query("SHOW TABLES");
while($row = mysql_fetch_row($res)) {
    echo $row[0] . "<br>";
// *** the above debug code should display all the tables in your database
// *** if not, something is wrong with the connection

If redirection does not work you should check the path you get generated. Do something like this between lines 15 and 16:

// *** DEBUG CODE 2
// *** the above code will print out the path for redirection and stop the script
// *** check the path if it is correct

header(sprintf("Location: %s", $insertGoTo));

hi thank you to answer me insert worked fine on server too just before 1 hours dont work too so for the moment i want only solver the redirection i have post for the insert into in the forum, so for the moment just rediraction

 $insertGoTo = "../myspace/order-line.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
    echo $insertGoTo;
  die ($insertGoTo);
  header(sprintf("Location: %".$insertGoTo));

OK. Please mark this thread as solved.
