Need Help...!!!

am a new developer in the php.
Now am doin a school management proect , for that i need to create a Login page.
When i was running the code error occurs.

This is the code :

<?php
$host="192.168.60.26";
$db="temp";
$user="root";
$pass="";
mysql_pconnect($host,$user,$pass);
mysql_select_db($db);
if(isset($_POST['Submit']))
{
$username=$_POST['Username'];
$password=$_POST['Password'];

/*Verify that user is in database */
$user = mysql_query("SELECT Username FROM ".registration." WHERE Username = '$username'");

if($row = mysql_fetch_array($user,MYSQL_ASSOC))
{
$pass = mysql_query("SELECT Password FROM ".registration." WHERE Username = '$username' ");

if($row = mysql_fetch_array($pass,MYSQL_ASSOC))
{
if($row{'Password'}=="")
{
echo " Your Password is incorrect..!!!";
}
else
{
header('Location: next.php'); //Success! Username and password confirmed
}
}
else
{
echo " Your Username or Password is incorrect...!!!"; //Indicates password failure
}
}
else
{
echo " Username is incorrect..!!!!";
}
}
?>

NB: There is no white spaces before and aftr the php code( <?...?>)
the code checks only the username....
when am click the submit button it is directly go to the next.php
and also it goes wen i am entering the wrong password.

Please anyone help this new php programmer.

 

Please post the error as well, root does not have any password!! did you not configure the database?

 

You're not checking your user submitted password ( = $password) !

You're probably checking the original password from the table ($pass) and that will always be correct.

(ps. re-using variables (like $row and $pass) for different purposes makes your code much harder to read)
