but when it came to testing it....I got nothing

 

I am trying to make a chatroom using 3 pages...

 

index.php - where the data is displayed

request.php - whereI select the data from database I need

ajax.js - which is meant to access request.php every 10 milliseconds, and pull the stuff through into index.php

 

at the moment I have an incling that it might be retrieving the variable in the link request.php?room=$room (room being which chat room it is in index.php?room=$room)

 

index.php

<?
include 'db.php'; // Connect to DB
$email = $_COOKIE['email']; 
$password = $_COOKIE['password']; 
if((!$email) || (!$password)){ 
echo "There was an error in your details.<br />"; 
include 'http://www.lordoftheabyss.com/index.php'; 
exit(); 
}else{
$sql = mysql_query("SELECT * FROM users WHERE email='$email'");
$mem = mysql_fetch_array($sql);

$que = mysql_query("SELECT * FROM quests") or die(mysql_error());
$quest = mysql_fetch_array($que);
?>

</td>
</table>

request.php

<?
include 'db.php';

$blah = mysql_query("SELECT * FROM chat WHERE room = '$room' ORDER BY id DESC LIMIT 20") or die(mysql_error());
while($chat = mysql_fetch_array($blah)){
echo "$chat[message]<br>";
}

?>

 

ajax.js

    function createRequestObject() { 
     
        var req; 
     
        if(window.XMLHttpRequest){ 
            // Firefox, Safari, Opera... 
            req = new XMLHttpRequest(); 
        } else if(window.ActiveXObject) { 
            // Internet Explorer 5+ 
            req = new ActiveXObject("Microsoft.XMLHTTP"); 
        } else { 
            // There is an error creating the object, 
            // just as an old browser is being used. 
            alert('There was a problem creating the XMLHttpRequest object'); 
        } 
     
        return req; 
     
    } 
     
    // Make the XMLHttpRequest object 
    var http = createRequestObject();

function sendRequest(request) { 
         
        // Open PHP script for requests 
var room = gup('room');
var url = 'request.php?room=' + room;
        http.open('get', 'url'); 
        http.onreadystatechange = handleResponse; 
        http.send(null); 
     
    } 
     
    function handleResponse() { 
     
        if(http.readyState == 4 && http.status == 200){ 
     
            // Text returned FROM PHP script 
            var response = http.responseText; 
     
            if(response) { 
                // UPDATE ajaxTest content 
                document.getElementById("countPosts").innerHTML = response; 
                setTimeout(countPosts,20); 
            } 
     
        } 
    } 

    function countPosts() { 
        sendRequest('countPosts'); 
    }

 

anything put forward would be greatly appreciated

changed it a bit, there is only 1 room now so it doesn't send the $room to request.php anymore....yet it still doesn't work!!

 

index.php -

This is the only relevant code

<div id="show()" style="height: 300px; width: 500px; overflow: auto; background-color: #CCCCCC; border: 1px solid #555555;"></div>

 

request.php -

<?
include 'db.php';

$blah = mysql_query("SELECT * FROM chat ORDER BY id DESC LIMIT 20") or die(mysql_error());
while($chat = mysql_fetch_array($blah)){
echo "$chat[message]<br>";
}

?>

 

ajax.js -

    function createRequestObject() { 
     
        var req; 
     
        if(window.XMLHttpRequest){ 
            // Firefox, Safari, Opera... 
            req = new XMLHttpRequest(); 
        } else if(window.ActiveXObject) { 
            // Internet Explorer 5+ 
            req = new ActiveXObject("Microsoft.XMLHTTP"); 
        } else { 
            // There is an error creating the object, 
            // just as an old browser is being used. 
            alert('There was a problem creating the XMLHttpRequest object'); 
        } 
     
        return req; 
     
    } 
     
    // Make the XMLHttpRequest object 
    var http = createRequestObject();

function sendRequest() { 
        http.open('get', 'request.php'); 
        http.onreadystatechange = handleResponse; 
        http.send(null); 
     
    } 

    } 

    function show() { 
        sendRequest('show'); 
    }

    function handleResponse() { 
     
        if(http.readyState == 4 && http.status == 200){ 
     
            // Text returned FROM PHP script 
            var response = http.responseText; 
     
            if(response) { 
                // UPDATE ajaxTest content 
                document.getElementById("show").innerHTML = response; 
                setTimeout(show,20); 
	alert(OMG);
            } 
     
        }
