is the query failing?

is the # of rows returned not == 1?

have you tried echoing the sql and running it in a sql client to see what happens?


also, "my code doesnt work" is hard to debug. Try to be more specific.

Everything is fine without the use of md5. But if i put md5 to encrypt the password its not working. While registering also i'm putting md5 and for login also i'm using md5. But i don't know why its not working when i use md5. Pls reply me as soon as possible. Thanks :-)

Have you tried a debug?

Example, set the value of the password in the database in a variable called $dbpw, then create a variable by using $userpw = md5($_POST['password'];

Then echo the two to the screen from a test script. See if they are the same first.

Try making this line 58 and 59

$qry='SELECT * FROM employee WHERE username="'.mysql_real_escape_string($login).'" AND passwd="'.mysql_real_escape_string(md5($_POST['password'])).'"';
$result=mysql_query($qry) or die(mysql_error());

I have added some debugging functions which should help resolve the error.
