RE:[PHP] login problem fixed!!

[snip] please note this will only catch invalid queries. To catch the event of the query being perfectly fine, but nothing coming back, just check the values of num_rows or affected_rows (depending on the query). [/snip] um....?? this way doesnt work for some strange reason... testing affected_rows returns always with 0 so: if(mysql_affected_rows()==0){...} will always get ran even if the query itself returned an invalid user login... num_of_rows will always return true and never false i guess because when $result (the query itself) is "invalid" or returns the fact that the user typed a wrong username and or password the db server returns NULL, false or rightfully 0. thus the error: num_of_rows() is not a valid resource type in:......login.php error so as far as i know i have to test the literall existance of the $result resource being true (a real login) or false (the login failed)... at this point i cant test for $_SESSION['username'] because it hasnt been registered yet... anyhow..off my soap box
