Switch case virker ikke

Min switch via url virker ikke.

Kode:

index.php :

<?php

echo '<a href="index.php?page=index2">index2</a>';



switch($_GET['page'])
{
  case 'vis_produkt':
      include('vis_produkt.php');
      //break;
     
    case 'index2':
      include('index2.php');
      //break;
       
   
}


?>

index2.php :

<?php

//include_once 'connect.php';
include 'connect.php';

class Video {
  public $titel;
 
  function udskrivVideo() {
        echo "<p>".$this->titel." </p>";
  }
}


$test_1 = new Video();
$test_2 = new sql();
$test_2->connect();
$test_2->q("SELECT * FROM navn");
while($array = $test_2->a()){
  echo $array["fornavn"]."<br />";
  echo $array["efternavn"]."<br /><br />";
  echo '<a href="index.php?page=vis_produkt&id='. $array["id"] .'">Link</a><br>';
}
$test_2->close();
$test_1->udskrivVideo();


?>

connect.php :

<?php

class sql
{
    var $_conn;
    var $_queries = array();
    var $_activeQuery;
  /* husk at indsætte de rigtige oplysniner til din database */
    function connect(){
      $dbhost = "localhost";
      $database = "oop";
      $dbuser = "root";
      $dbpass = "";
   
      $this->_conn = mysql_connect($dbhost, $dbuser, $dbpass);
      mysql_select_db($database, $this->_conn);
    }
 
    function q($sql_query){
        $query = mysql_query($sql_query, $this->_conn) or die(mysql_error());
      if($query !== false){
          array_unshift($this->_queries, $query);
        $this->_activeQuery = $query;
        return true;
      }
      return false;
    }
  /* Fjernede $q fordi jeg ikke lige kunne regne ud hvorfor den var der */
    function a(){
        $array = null;
      if($this->_activeQuery){
          $array = mysql_fetch_array($this->_activeQuery, $this->_conn);
      }
      return $array;
    }
 
    function free(){
        if($this->_activeQuery){
          @mysql_free_result( $this->_activeQuery );
        $this->_activeQuery = array_shift( $this->_queries );
      }
    }
 
    function num_rows(){
        return mysql_num_rows($this->_activeQuery);
    }
 
    function close(){
      @mysql_close($this->_conn);
    }
}
?>

Fejl den siger:

Warning: mysql_fetch_array() [function.mysql-fetch-array]: The result type should be either MYSQL_NUM, MYSQL_ASSOC or MYSQL_BOTH. in C:\wamp\www\test\connect.php on line 32
