It's my first day here, I thought you guys could help me. So, I'm working on this kind of chatting service for a friend. I want it to auto update anything inside the div tags that has an id of messages. I tried adding some javascript and stuff from other posts, but they just made it worse. So, if anyone could fix it and comment, or give me suggestions. I want it as soon as someone posted something, it updates the posts in the div tags with the id of messages.
<?php
session_start();
if(!isset($_SESSION['username']))
{
header("Location: /index.php");

I hope you guys can help me, thank you.
First create a page message.php as:
<?php
session_start();
?>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function()
{
$('#submit').click(function()
{
//alert("hello");
// ss=document.getElementById("message").value;
$.ajax({
type : 'POST',
url : 'active.php',
data: {
messages :$('#message').val()
},
success : function(data){
$('#messages').html(data);
}
});
});
});
</script>
<title>

<style>
body
{
background: #383838;
font-family: Arial;
color: #444444;
position: absolute;
top: 50%;
left: 50%;
margin-top: -75px;
margin-left: -150px;
}
form
{
background: #ffffff;
width: 270px;
border-radius: 15px;
box-shadow: 3px 3px 6px 1px #303030;
}
input
{
margin-left: 15px;
}
p
{
margin-left: 15px;
}
error
{
padding:2px 4px;
margin:0px;
border:solid 1px #FBD3C6;
background:#FDE4E1;
color:#CB4721;
font-size:14px;
font-weight:bold;
}
div
{
background: #f0f0f0;
}
hr
{
color: #d0d0d0;
background-color: #d0d0d0;
height: 3px;
border: 0px;
}
username
{
margin-left: 5px;
}
message
{
margin-left: 10px;
}
</style>
</head>
<body>
<center>
<error>Please enter a message to send.</error> <br />
</center>
<br />
<form action="active.php" method="POST">
<br />
<p>Message</p>
<input type="text" name="message" id="message" /> <br />
<br />
<input type="button" id="submit" name="submit" value="Submit" /> <br />
</form>
<br />
<div id="messages">
</div>
</body>
</html>
<script language="JavaScript"><!--
// v3 compatible:
function doSomething() {
// do something here...
$.ajax({
type : 'POST',
url : 'active.php',
data: {
messages :$('#message').val()
},
success : function(data){
$('#messages').html(data);
}
});
setTimeout('doSomething()',3000);
}
setInterval('doSomething()',3000);
//--></script>
Then Create a page active.php as
<?php
session_start();
$connect = mysql_connect("localhost", "root", "");
mysql_select_db("test");
$username=$_SESSION['username'];
$message=$_POST['messages'];
if($message!="")
{
mysql_query("INSERT INTO messages VALUES('', '$username', '$message')");
}
$query = mysql_query("SELECT * FROM messages ORDER BY id DESC limit 1,0");
$num_rows = mysql_num_rows($query);
if($num_rows > 0)
{
while($row = mysql_fetch_assoc($query))
{
$username = $row['username'];
$message = $row['message'];
?>
<div>
<br /> <username><b><?php echo $username; ?></b></username>
<hr />
<message><?php echo $message; ?></message> <br />
<br /> </div>
<br />
<?php
}
}
else
{
echo"No message to show";
}
?>
