[SOLVED] Ajax isn't running

[BillyBoB]

I am creating a chat for my upcoming game and I am trying to build the users list.

 

Javascript:

function getUsers(divId, userId) {
obj = document.getElementById(divId);

if (userReq.readyState == 4 || userReq.readyState == 0) {
	userReq.open("GET", "../includes/getUsers.php?anticache=0", true);
	userReq.onreadystatechange = function() {
		alert(userReq.readyState + " - " + userReq.status);
		if (userReq.readyState == 4 && userReq.status == 200) {
			so_clearInnerHTML(obj);

			var xmldoc = userReq.responseXML;
			var user_nodes = xmldoc.getElementsByTagName("user");
			var n_users = user_nodes.length
			for (i = 0; i < n_users; i++) {
				var id_node = user_nodes[i].getElementsByTagName("id");
				var name_node = user_nodes[i].getElementsByTagName("name");
				var perms_node = user_nodes[i].getElementsByTagName("perms");

				eDIV = document.createElement('div');
				if(perms_node[0].firstChild.nodeValue==1) {
					eIMG = document.createElement('img');
					eIMG.setAttribute('src', '../images/icons/ModHammer.jpg');
					eIMG.setAttribute('alt', 'Moderator');
					eDiv.appendChild(eIMG);
				}
				if(id_node[0].firstChild.nodeValue==userId) {
					eDiv.appendChild(document.createTextNode(name_node[0].firstChild.nodeValue));
				}else{
					eAnchor = document.createElement('a');
					eAnchor.onclick = function() { UserPopup(event) };
					eAnchor.appendChild(document.createTextNode(name_node[0].firstChild.nodeValue));
					eDiv.appendChild(eAnchor);
				}
				obj.appendChild(eDiv);
			}
		}
	}
	receiveReq.send(null);
	alert('hi');
}
uTimer = setTimeout('getUsers(\'UserNames\',\''+userId+'\')', 2000);
}

 

PHP:

<?php
require_once("functions.php");
require_once("objects.php");

$db = new Database("syck_polkamon");
$db->connectDB("syck","4<N#ly11TGn<");

//Send some headers to keep the user's browser from caching the response.
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT" );
header("Last-Modified: " . gmdate( "D, d M Y H:i:s" ) . "GMT" );
header("Cache-Control: no-cache, must-revalidate" );
header("Pragma: no-cache" );
header("Content-Type: application/xml; charset=utf-8");

//Create the XML response.
$xml = '<?xml version="1.0" ?><root>';

/*<user><id></id><name></name><perms></perms></user>*/
$i = 0;
$sql = mysql_query("SELECT * FROM `chat_users`");
while($info = mysql_fetch_array($sql)) {
$id[$i] = $info['id'];
$i++;
}

$i = 0;
foreach($id as $uid) {
$sql = mysql_query("SELECT * FROM `user_profiles` WHERE `id` = '$uid'");
$info[$i] = mysql_fetch_array($sql);
$i++;
}

$j = 0;
$h = 0;
foreach($info as $user) {
$sql = mysql_query("SELECT * FROM `user_files` WHERE `id` = '$user[id]'");
$inf = mysql_fetch_array($sql);
if($inf['perms']==1) {
	$mods[$j] = $user;
	$j++;
}else{
	$regs[$h] = $user;
	$h++;
}
}

if($mods[0]) {
foreach($mods as $mod) {
	$xml .= '<user>';
	$xml .= '<id>' . $mod['id'] . '</id>';
	$xml .= '<name>' . $mod['username'] . '</name>';
	$xml .= '<perms>1</perms>';
	$xml .= '</user>';
}
}

if($regs[0]) {
foreach($regs as $reg) {
	$xml .= '<user>';
	$xml .= '<id>' . $reg['id'] . '</id>';
	$xml .= '<name>' . $reg['username'] . '</name>';
	$xml .= '<perms>0</perms>';
	$xml .= '</user>';
}
}

$xml .= '</root>';
echo $xml;
?>

 

The php works fine http://syckgamingleague.com/includes/getUsers.php but for some reason the ajax isn't pulling that info.... as you can see I have it alert the status and readyState but these do not alert at all so it has to be around that line

 

Thanks in advance

I'm officially going to stop coding while I'm tired. I messed up on the send variable.
