unemployment Posted October 21, 2013 Share Posted October 21, 2013 I have a running chat application in my website. It is implemented using websockets, php and is working fine. The problem is whenever i send a message to single user it broadcasts that message to all users currently connected to my website. It will be really helpful if someone can tell me how to get the unique id of each user when someone connects to our app. If i can get the userid of the current logged in chat user that would solve my problem but i am unable to retrieve that userid when the user connects (open state of websocket). I can get the userid when the connection is made but I need the userid before the connection happens. When the connecation occurs it assigns its own ids to the connected users in a serial manner(1,2,3..,n). <?php // prevent the server from timing out set_time_limit(0); // include the web sockets server script (the server is started at the far bottom of this file) require 'class.PHPWebSocket.php'; // when a client sends data to the server function wsOnMessage($clientID, $message, $messageLength, $binary) { global $Server; $ip = long2ip( $Server->wsClients[$clientID][6] ); // check if message length is 0 if ($messageLength == 0) { $Server->wsClose($clientID); return; } //Send the message to everyone but the person who said it foreach ( $Server->wsClients as $id => $client ) if ( $id != $clientID ) $Server->wsSend($id, "Visitor $clientID ($ip) said "$message""); } // when a client connects function wsOnOpen($clientID) { global $Server; $ip = long2ip( $Server->wsClients[$clientID][6] ); $Server->log( "$ip ($clientID) has connected." ); //Send a join notice to everyone but the person who joined foreach ( $Server->wsClients as $id => $client ) if ( $id != $clientID ) $Server->wsSend($id, "Visitor $clientID ($ip) has joined the room."); } // when a client closes or lost connection function wsOnClose($clientID, $status) { global $Server; $ip = long2ip( $Server->wsClients[$clientID][6] ); $Server->log( "$ip ($clientID) has disconnected." ); //Send a user left notice to everyone in the room foreach ( $Server->wsClients as $id => $client ) $Server->wsSend($id, "Visitor $clientID ($ip) has left the room."); } // start the server $Server = new PHPWebSocket(); $Server->bind('message', 'wsOnMessage'); $Server->bind('open', 'wsOnOpen'); $Server->bind('close', 'wsOnClose'); // for other computers to connect, you will probably need to change this to your LAN IP or external IP, // alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME'])) $Server->wsStartServer('127.0.0.1', 9300); ?> <!doctype html> <html> <head> <meta charset='UTF-8' /> <style> input, textarea {border:1px solid #CCC;margin:0px;padding:0px} #body {max-width:800px;margin:auto} #log {width:100%;height:400px} #message {width:100%;line-height:20px} </style> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script src="fancywebsocket.js"></script> <script> var Server; function log( text ) { $log = $('#log'); //Add text to log $log.append(($log.val()?"n":'')+text); //Autoscroll $log[0].scrollTop = $log[0].scrollHeight - $log[0].clientHeight; } function send( text ) { Server.send( 'message', text ); } $(document).ready(function() { log('Connecting...'); Server = new FancyWebSocket('ws://127.0.0.1:9300'); $('#message').keypress(function(e) { if ( e.keyCode == 13 && this.value ) { log( 'You: ' + this.value ); send( this.value ); $(this).val(''); } }); //Let the user know we're connected Server.bind('open', function() { log( "Connected." ); }); //OH NOES!

QuickOldCar Posted October 21, 2013 Share Posted October 21, 2013 Two ideas that come to mind. Start saving users with an autoincrement id,username,ip into a db, and call on that first. Some sort of login system used to determine guest or user, if is a user generate a guest_number incremented. Create sessions storing ip and datetime, set a cache expire on them, grab their real ip and use as the unique id. Quote Link to comment Share on other sites More sharing options...
