         req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

     }
}
[/code]
and html form
[code]<form name='namechange' onsubmit='return false;'>
         <input type='text' name='ftpname' value='$row[1]' />
  <input type='hidden' name='id' value='$row[0]' />
            <input type='submit' value='Gönder' onclick='yolla('namechange', 'name_change.php', 'warn');' />
     </form>[/code]
what is wrong with these codes?  :(

How about you start by telling us what isn't working right so we don't have to sort through it all?

By the way:
value='$row[0]' without enclosing that in PHP tags, it's not going to put the value in there.
