[php, mysql] pytanie o sesje Opcje

[!*!]

mam coś takiego:

formularz logowania:

Kod

<form class="register" action="index2.php" method="post">
<fieldset>

<div class="inputy2">Logowanie - tu będzie opis<br />Logowanie - tu będzie opis<br />Logowanie - tu będzie opis<br /></div>

<div class="inputy4">Panel logowania</div>
<div class="inputy3" style="display:table;">
<p style="display:table-row;">
<span style="display:table-cell;">Nazwa użytkownika: </span><span style="display:table-cell;"><input type="text" class="text" name="user" maxlength="15" /></span></p>
<br />
<p style="display:table-row;">
<span style="display:table-cell;">Hasło: </span><span style="display:table-cell;"><input type="password" class="text" name="pass" maxlength="15" /></span></p></div>

<br />
<input type="submit" name="sprawdz" value='Zaloguj się'></div>

</fieldset>
</form>
</div>

tak w teori powinno wygladac cos oparte na sesjach:

Kod

<?php
  session_start();
  if (isset($_POST['submit'])) {
    $_SESSION['imie'] = $_POST['imie'];
  } else {
    header("Location: index2.php");
  }
?>

index2.php

Kod

<?php


  // If there is no cookie presesnt
  if (!isset($_COOKIE['cookie_info'])) {

      // Variables that data come from the form
      $username = $_POST["user"];
      $password = $_POST["pass"];

      // Check if username and password where submitted
      if (!$username) {
          echo "Niejesteś zalogowany"; exit;
      }
      if (!$password) {
          echo "Please enter password"; exit;
      }

      // Use Connect Script
      include("connect.php");

      // MD5 Username and Password
      $username = MD5($username);
      $password = MD5($password);

      // Check if username exists. If not then say no such username.
      $issuchusername = mysql_query("SELECT * FROM userdata WHERE userid = '$username'");
      $usernamelogin = mysql_num_rows($issuchusername);

      // If username exists
      if ($usernamelogin == 1) {

          $issuchpassword = mysql_query("SELECT * FROM userdata WHERE userid = '$username' AND userpass = '$password'");
          $passwordlogin = mysql_num_rows($issuchpassword);

          // If password is correct
          if ($passwordlogin == 1) {

              $time = time();
              $cookie_data = $username.'-'.$password;
              if(setcookie ("cookie_info",$cookie_data, $time+3600)==TRUE) {
              }
              else {
                  echo "You computer does not support cookies. <BR> To view other pages after logged in you need to have cookies enabled.<BR>";
              }

          }
          else {
              echo "Incorrect username/password";
              exit;
          }
      }
      else {
          echo "Incorrect username/password";
          exit;
      }
  }
  // End if no cookie present

?>
    <?php

  // Use Connect Script
  include("connect.php");

// Use cookie and Extract the cookie data (Username and Password)
  $cookie_info = explode("-", $_COOKIE['cookie_info']);
  $namecookie = $cookie_info[0];
  $passcookie = $cookie_info[1];

  if (!isset($_COOKIE['cookie_info'])) {
      $namecookie = $_POST["user"];
      $passcookie = $_POST["pass"];

  }

  // MD5 Username and Password
  $namecookie = MD5($namecookie);
  $passcookie = MD5($passcookie);

  // Check if username exists. If not then say no such username.
  $issuchusername = mysql_query("SELECT * FROM userdata WHERE userid = '$namecookie'");
  $usernamelogin = mysql_num_rows($issuchusername);

  // If username exists
  if ($usernamelogin == 1) {
      $issuchpassword = mysql_query("SELECT * FROM userdata WHERE userid = '$namecookie' AND userpass = '$passcookie'");
      $passwordlogin = mysql_num_rows($issuchpassword);

      // If password is correct
      if ($passwordlogin == 1) {

          // User is now logged in, display details of user

          // Get details of user from Database and put them in variables
          $query = mysql_query("SELECT * FROM userdata WHERE userid = '$namecookie'");
          $nameuser = mysql_result($query,0,13);
          $name = mysql_result($query,0,2);
          $address = mysql_result($query,0,3);
          $suburb = mysql_result($query,0,4);
          $state = mysql_result($query,0,5);
          $postcode = mysql_result($query,0,6);
          $phone1 = mysql_result($query,0,7);
          $phone2 = mysql_result($query,0,8);
          $emailaddress = mysql_result($query,0,9);
          $joineddate = mysql_result($query,0,10);

          

?>

czyli aby oprzec to na sesji mam zrobić coś takiego:

Kod

<?php
  session_start();
  if (isset($_POST['submit'])) {
    $_SESSION['username'] = $_POST['user'];
    $_SESSION['password'] = $_POST['pass'];
  } else {
    header("Location: index2.php");
  }
?>

i dać to gdzie?
