HI every1 i am a new guy in mysql-php. this 4 lines are making big problem to my web application $a = $_GET['id']; $servisoi = trim($_GET['servisoi']); $tekst = " Update klientet set servisoi='$servisoi' where id=$a "; // echo $tekst; mysql_query($teskt) or die (mysql_error()); they always return the "Query was empty", however if i uncomment the fourth line it prints a very good sql query text. any help ?
