Login.php

<div class="body">
   <div class="body_resize">
          <div class="left">
       <h2>Prisijungimas</h2>
       <p>
<?php
if (isset ($_POST['login'])) {
$pass = md5 ($_POST['password']);
$_POST['nickas'] = addslashes ($_POST['nickas']); 
require "connect.php";
$check = mysql_query ("SELECT * FROM USERS where nickas = '". $_POST['nickas'] ."'");
$chec2 = mysql_num_rows ($check);
if ($chec2 == 0) {
print "Vartotojas neregistruotas";
} else {
while ($infoUser = mysql_fetch_array($check)){
	if ($pass != $infoUser ['password']) {
		print "Neteisingas slaptazodis"; }
		else {
			$time = time ()+ 3600;
			setcookie(nickas,$_POST['nickas'],$time);
			setcookie(pass,$pass,$time);
			header("Location: index.php");



		}
		}}}
?>



<form action="index.php?id=log" method="post"/>
Slapyvardis:
<input type="text" name="nickas" /><br>
Slaptazodis:
<input type="password" name="password"/><br>
<input type="submit" name="login" value="Jungtis" />
</form>



</p>       

     </div>

functions.php

<?php
$nick = $_COOKIE['nickas'];
$nick = $_COOKIE['pass'];
function online () {
global $nick, $pass;
require "connect.php";
$check = mysql_query ("SELECT * FROM users WHERE nickas = '$nick' and password = '$pass'");
$chec2 = mysql_num_rows ($check);
if ($chec2 == 0) {
$online = 0;
} else {
$online = 1;
}
return $online;
}


?>

index.php esu nurodes:

  	  	  <?php
  require "functions.php";
  ?>

 <?php
 $id = $_GET['id'];
 switch ($id) {
  case 'log':
  require "login.php";
  break;
  	  case 'reg':
  require "reg.php";
  break;
  default:
  require "index2.php";

 }

index2.php

<div class="body">
   <div class="body_resize">
          <div class="left">
       <h2>Naujienos</h2>
