Hi All,

I need some help with the below code. I have this login code with me and its
working fine with my *localhost 'WAMP' *server. But when I tried to run the
same script on my web host server its not working. Every time its giving me
the same message "*please enter a username and a password*" which is a
condition within the script.


session_start();

$username = $_POST['username'];
$password = $_POST['password'];

if ($username&&$password)

{
$connect = mysql_connect("localhost", "tutor_root", "admin") or
die("couldn't connect");
mysql_select_db("tutor_register") or die("couldn't find db");


$query = mysql_query("SELECT * FROM register WHERE username ='$username'");
$numrows = mysql_num_rows($query);
if ($numrows!=1)

{
//code to login

while ($row =mysql_fetch_assoc($query))
{
$dbusername = $row['username'];
$dbpassword= $row['password'];

}
//check to see if they match

if ($username==$dbusername&&$password==$dbpassword)
{
echo "you are in here to enter the members
page";


$_SESSION['username']=$username;

}
else

echo "incorrect password";
}
else

die("That user dosen't exist");


}
else
die("pelase enter a username and a password");

Are the $_POST['username'] and $_POST['password'] variables present? You
didn't post any html form information so I think you could start there.

Re: Need help with the code

Add this to your script and just copy and paste it back. Seriously, you
are not going to get any help if you don't show anyone the output of
your problem.

echo "

";

var_dump(print_r($_GET));

var_dump(print_r($_POST));

echo "

Maybe you should google for information regarding the php.ini and error
reporting.
