1. Do you know when there is a new message?
2. Do you know how to modify that event so that it calls a function like playsound()?
3. Do you know how to play a sound?
Below is the code. when i try to integrate the sound into chat application. the sound stops working
Code:
<?php
session_start();
if(isset($_POST['submit']))
{
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("chat", $con);
$message=$_POST['message'];
$sender=$_POST['sender'];
mysql_query("INSERT INTO message(message, sender)VALUES('$message', '$sender')");
}
?>
