I solved it myself...............
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title></title>
<form action="" method="post" >
Name:<input type="text" name="un"> <br>
Password:<input type="password" name="un2"/> <br>
<input type="submit" value="submit" name="submit" />
</form>
</head>
<body>
= mysql_real_escape_string($_POST[="INSERT INTO empname (empName) VALUES ('$text')"
</body>
</html>
