Simple question about cookies

[Gruzin]

hi guys,
Here is my little problem: if the cookies is set redirect user to the page and if not redirect to another page. Here is the code, please tell me what I'am not doing correctly, thanks in advance.

P.S I use this to set cookies, but it's included in other page:
[code]<?php
setcookie("login", time()+60);
?>[/code]

[code]<?php
if(isset($HTTP_COOKIE_VARS["login"])){
header ('Location: http://www.mysite.net/admin.php'); // if cookies are set redirect user to the admin panel
}
else{
header ('Location: http://www.mysite.net/log.php');
}
?>[/code]

} else {
echo '<meta http-equiv="Refresh" Content="0; URL=http://www.mysite.net/log.php">';

sorry but it doesn't work for me... Any other ideas? thanks for your time

[newb]

why not use sessions instead

[Gruzin]

Is that the solution? I don't know, I'am just a biginner :)
Where can I find good tutorial of sessions? And can I check if cookie is set using sessions? thank u very much for your help.

[newb]

yes you can. sessions are much easier to use then cookies. here's my code, it should work for u:

[code]
<?php
session_start();
if(isset($_SESSION['username']))
{
$ses_user = $_SESSION['username'];
echo "You are already logged in, $ses_user. Redirecting to User CP...";
echo "<meta http-equiv='refresh' content='3;url=http://mysite.com/index.php?name=usercp'>";
}
else
{

// Begin Login Code

if(isset($_POST['login']))
{
  $error = '';
  $username = $_POST['username'];
  $password = $_POST['password'];
 
  if(!isset($username) || !isset($password))
  {
  $error .= 'A required field was left blank.<br />';
  }
  $password = md5($password);

  if(get_magic_quotes_gpc())
  {
      $username = $username;
      }
      else
      {
      $username = addslashes($username);
      }
     
  $result = $libmysql->query("SELECT * FROM $table_users WHERE username='$username' AND password='$password'");
  $valid_login = mysql_num_rows($result);

  if($valid_login == 0)
  {
      $error .= 'The supplied username and/or password was incorrect.<br />';
      }
     
    if($error == '')
    {
        $data = mysql_fetch_array($result);
  $_SESSION['username'] = $data['username'];
          echo '<meta http-equiv="Refresh" Content="0; URL=http://mysite.com/index.php?name=usercp">';
          die();
      }
      else
  {
      echo 'The following errors were returned:<br />'.$error.'<br />';
    }
}
?>
[/code]

then for the usercp:
[code]
<?php
if(isset($_SESSION['username']))
{
echo "Welcome to the userCP $ses_user. You are logged in";
}
else
{
    echo "You aren't logged in.<br /><br />Please <a href='mysite.com/index.php?name=signup'>register</a> or <a href='mysite.com/index.php?name=usercp'>log in.</a>";
    }
?>
[/code]
