<?php

 

session_start ();

 

 

 

  $username = $_POST ['username'];

  $password = $_POST ['password'];

 

  

  

  if ($username&&$password)

  {

  $connect = mysql_connect ("localhost","root","") or die("Error");

  mysql_select_db('thesis') or die("Error");

  

  $query = mysql_query("SELECT * FROM student WHERE username ='$username'");

  $numrows = mysql_num_rows($query);

 

$query1 = mysql_query("SELECT * FROM admin WHERE username='$username'");

$row1 = mysql_fetch_assoc($query1);

$adusername = $row1['username'];

$adpassword = $row1['password'];

 

$queryid = mysql_query("SELECT id FROM student WHERE username ='$username'");

$row2 = mysql_fetch_assoc($queryid);

$id = $row2['id'];

 

 

if ($username==$adusername&&$password==$adpassword)

{

die(strval($_SESSION['username']=$username));

 

 

die ('<script type="text/javascript">

alert("Welcome Administrator !");

window.location = "adminpage.php";

</script>');

 

}

 

 

 

  if ($numrows!=0)

  {

  while ($row = mysql_fetch_assoc($query))

  {

  

  $dbusername = $row['username'];

  $dbpassword = $row['password'];

  

  }

  

  

if ($username==$dbusername&&$password==$dbpassword)

{

 

echo '<script type="text/javascript">

alert("Login Successful !");

window.location = "studhome.php";

</script>';

$_SESSION['username']=$username;

$_SESSION['id']=$id;

$_SESSION['name']=$name;

 

}

else

echo '<script type="text/javascript">

alert("Incorrect Password !");

window.location = "Login.php";

</script>';

 

}

else 

die('<script type="text/javascript">

alert("User not Registered !");

window.location = "Login.php";

</script>');

 

  }

else

die('<script type="text/javascript">

alert("Please Enter Username/Password !12121");

window.location = "Login.php";

</script>');

 

?>

I would use header versus all the javascript

It may help if you provide more information on what you are hoping to do.

 

For what it's worth, only the first call to the die() function will be executed. The second call never gets executed since die() terminates the PHP script. More information can be found here:

Why not echo the data and then kill the script?
