Ovo je kod pre zaglavlja <?php session_start(); if (isset($_POST['userid']) && isset($_POST['password'])&& !empty($_POST['userid'])&& !empty($_POST['password'])) {   // if the user has just tried to log in   $userid = $_POST['userid'];   $password = $_POST['password'];   $db_conn = new mysqli('localhost', 'root', 'haha', 'auth');   if (mysqli_connect_errno()) {    echo 'Connection to database failed:'.mysqli_connect_error();    exit();   }   $query = "select count(*) from authorized_users where name='$name' and password='$password'";   $result = $db_conn->query($query);   if ($result->num_rows >0 )   {     // if they are in the database register the user id     $_SESSION['valid_user'] = $userid;      }   $db_conn->close(); } ?>
Telo:

<?         if (isset($_SESSION['valid_user']))   {     echo 'Dobrodosli'."\t"."<strong>".$_SESSION['valid_user']."</strong>";     echo '<a href="logout.php">Log out</a><br />';   }   else   {     if (isset($userid))     {       // if they've tried and failed to log in       echo 'Could not log you in.<br />';     }       // provide form to log in     echo '<form method="post" action="index.php">';     echo '<table>';     echo '<tr><td>Userid:</td>';     echo '<td><input type="text" name="userid"></td>';     echo '<td>Password:</td>';     echo '<td><input type="password" name="password"></td>';     echo '<td colspan="2" align="center">';     echo '<input type="submit" value="Log in"></td></tr>';     echo '</table></form>';    }   ?>
E ovde imam jedan problem:Kad ukucam bilo koji username i password i ako ga nema u bazi on mi registruje sesiju sto ne bi trebalo,jel zna neko u cemu je problem?Hvala unared

COUNT uvek vraca 1 rezultat, a to je broj nadjenih rekorda, U tvom slucaju, vracen bi bio 1 rezultat a on bi bio broj 0. Umesto COUNT izvuci id i radice, ili umesto $result->num_rows izvuci vrednost COUNT-a...
