// now we conect to database


$con=mysql_connect('localhost','root');
if(! $con) die ("no localhost");
$db=mysql_select_db('school',$con);
if(! $db) die ("no db");

// this code will check if the login buuton was clicked and get the id , password of the user and chek if the password is correct and met the id


if(isset($_POST['submit']))
