[SOLVED] Output Error object HTMLCollection

BillyBoB · July 21, 2008

I am creating a chat script for my upcoming game and when I send for the username/time/message it fills all three variables with object HTMLCollection.. Here's the code.

javascript:

var sendReq = getXmlHttpRequestObject();
var receiveReq = getXmlHttpRequestObject();
var lastMessage = 0;
var mTimer;

function getXmlHttpRequestObject() {
if (window.XMLHttpRequest) {
	return new XMLHttpRequest();
} else if(window.ActiveXObject) {
	return new ActiveXObject("Microsoft.XMLHTTP");
}
}
function getMessages(chatRoomId, divId) {
obj = document.getElementById(divId);

if (receiveReq.readyState == 4 || receiveReq.readyState == 0) {
	receiveReq.open("GET", '../includes/getMessages.php?crid=' + chatRoomId + '&lm=' + lastMessage, true);
	receiveReq.onreadystatechange = function() {
		alert(receiveReq.readyState + " - " + receiveReq.status);
		if (receiveReq.readyState == 4 && receiveReq.status == 200) {
			var xmldoc = receiveReq.responseXML;
			var message_nodes = xmldoc.getElementsByTagName("message");
			var n_messages = message_nodes.length
			for (i = 0; i < n_messages; i++) {
				var user_node = message_nodes[i].getElementsByTagName("user");
				var text_node = message_nodes[i].getElementsByTagName("text");
				var time_node = message_nodes[i].getElementsByTagName("time");
				lastMessage = (message_nodes[i].getAttribute('id'));

				eDIV = document.createElement("div");
				eDIV.setAttribute("class","FullMessage");
				eAnchor = document.createElement("a");
				eAnchor.setAttribute("href","#");
				eAnchor.setAttribute("target","_blank");
				eAnchor.appendChild(document.createTextNode(user_node));
				eDIV.appendChild(eAnchor);
				eDIV.appendChild(document.createTextNode(" (" + time_node + "): " + text_node));
				obj.appendChild(eDIV);
				/*<div class="FullMessage"><a href="#" target="_blank">alyis</a> (9:25 AM): Hi everyone this is my first message in the chat room.</div>*/
			}
			mTimer = setTimeout('getMessages(' + chatRoomId + ',' + divId + ');',2000);
		}
	}
	receiveReq.send(null);
}
}

HTML:

<body onload="scrollBottom('ChatRoom'); getMessages('1','ChatRoom');">

Second HTML peice:

<div id="ChatRoom">
</div>

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>';

if($_GET['lm']==0) {
    $sql = mysql_query("SELECT * FROM `chat_terminal` WHERE `chatid` = '$_GET[crid]' ORDER BY `timesent` DESC LIMIT 20");
    while($info = mysql_fetch_array($sql)) {
        $xml .= '<message id="' . $info['id'] . '">';
        $sql2 = mysql_query("SELECT * FROM `user_profiles` WHERE `id` = '$info[userid]'");
        $info2 = mysql_fetch_array($sql2);
        $xml .= '<user>' . htmlspecialchars($info2['username']) . '</user>';
        $xml .= '<text>' . htmlspecialchars($info['message']) . '</text>';
        $time = getDBDate('g:i A', $info['timesent']);
        $xml .= '<time>' . $time . '</time>';
        $xml .= '</message>';
    }
}else{
    $sql = mysql_query("SELECT * FROM `chat_terminal` WHERE `chatid` = '$_GET[crid]' AND `id` > '$_GET[lm]' ORDER BY `timesent` DESC");
    while($info = mysql_fetch_array($sql)) {
        $xml .= '<message id="' . $info['id'] . '">';
        $sql2 = mysql_query("SELECT * FROM `user_profiles` WHERE `id` = '$info[userid]'");
        $info2 = mysql_fetch_array($sql2);
        $xml .= '<user>' . htmlspecialchars($info2['username']) . '</user>';
        $xml .= '<text>' . htmlspecialchars($info['message']) . '</text>';
        $time = getDBDate('g:i A', $info['timesent']);
        $xml .= '<time>' . $time . '</time>';
        $xml .= '</message>';
    }
}

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

It displays:

[object HTMLCollection] ([object HTMLCollection]): [object HTMLCollection]

Thanks in advance.
