[efim]

i cannot register and log in with the registered name even though in the user is in database.

e.g
if i am registered as

username :mike
password: 1234567


if i log in with this account, i have an error saying user does not exist. the error applies to both username and password.

at 1st i thought it was my md5 encryption, but i increased the password value in the db to 100

thanks


login.php

<?php
//  login script

   $connect= mysql_connect("localhost" , "root", "oooo") or die("Couldn't  connect!");
  mysql_select_db("cms") or die ("couldn't find db");
 
         $query = mysql_query("SELECT * FROM users WHERE username='$username'");  //matching db username with that which has been typed.
 
    $numrows = mysql_num_rows( $query );  //count the number of rows that ve  been retrieve from the db
