The code confuses me a bit.  The relevant code seems the following:

$(document).ready(function(){
   $("select#game").change(function(){

      var post_string = "game=" + $(this).val();
      
      $.ajax({
           type: 'POST',
           data: post_string,
           cache: false,
           dataType: 'game_type',
           url: 'json.php',
           timeout: '2000',
              error: function() {
                 alert("Error has occured");
              },
           success: function(data) {
                
                   alert(data.length);
                   alert(data[1].text);     
           }
         });
   });
});

 

with the line

 url: 'json.php',

You're calling the file json.php.

Is the code you pasted in your last post indeed json.php?

 

Offtopic why are you using  ob_start,  ob_clean and die if I may ask?

<?php 
ob_start();
?>
<!DOCTYPE html>
<html>
<head>
  <script type="text/javascript" src="/ajax/jquery/libary/jquery.js"></script>
</head>
<body>
<?php
if ($_POST['game'] == 1)
{

$array = array(
   'game_type' => array(
        array('value' => 1, 'text' => 'CTF'), 
        array('value' => 1, 'text' => 'TDM'), 
    ),
    'division' => array(
        array('value' => 1, 'text' => 'Division 1'), 
        array('value' => 1, 'text' => 'Division 2')
    ));
    
ob_clean();
header('Content-Type: application/json');
die(json_encode($array));
}
elseif ($_POST['game'] == 2)
{

$array = array(
   'game_type' => array(
        array('value' => 1, 'text' => 'TKOTH'), 
        array('value' => 1, 'text' => 'DM'), 
    ),
    'division' => array(
        array('value' => 1, 'text' => 'Division 3'), 
        array('value' => 1, 'text' => 'Division 4')
    ));

ob_clean();
header('Content-Type: application/json');
die(json_encode($array));
}
?>
<form>
<script>	
$(document).ready(function(){

var game_type_value = $('#game_type').text();
var division_value  = $('#division').text();

$("#game").change(function() {

	if ($('#game option:selected').text() == "")
    	{
    		$('#game_type').empty();
    		$('#division').empty();
   		 	$('#game_type').text(game_type_value);
      		$('#division').text(division_value);
    	}
    	
	var post_string = "game=" + $(this).val();

	$.ajax({
		  type: 'POST',
		  data: post_string,
		  cache: false,
		  dataType: 'json',
		  url: 'json.php',
		  timeout: '2000',
	       error: function(data) { 
	       		console.log(data);
	        },
		    success: function(data) {
			    
	        	$.each(data, function(prop, obj){

	            	switch(prop)
		        	{
		        		case 'game_type':
		        			$('#game_type').empty();
		        			$.each(obj, function(i, val){ 
		        			var game_type_row =$('<label>' + val.text +'</label><input name=\"\" id=\"\" type=\"checkbox\" value=\"'+ val.value +'\" />');
		      				$(game_type_row).appendTo('#game_type');
			        	    });
		        		break;
		        		
		        		case 'division':
		        			$('#division').empty();
		        			$.each(obj, function(i, val){
		        			var division_row = $('<label>' + val.text +'</label><input name=\"\" id=\"\" type=\"checkbox\" value=\"'+ val.value +'\" />');
			        		$(division_row).appendTo('#division');
			        		});
		        		break;
		        	}			  
	           });
		   }
      });
});
});

</script>
<select name="game" id="game">
<option value=""></option>
<option value="1">Counter Strike</option>
<option value="2">COD</option>
</select>

<div id="game_type">
please select a game...</div>
<div id="division">
please select a game...</div>
</form>

</body>
</html>

 

but there is one question i need to have two clauses in the line $("#game").change(function() {

 

something like $("#game").change || $("#game").text(function() {
