copied!<p>Had a very similar issue couple of days back and looks like socket.io had some changes in the API. I have never worked with symfony and am hoping the issues are the same.</p> <p>I have a working demo of socket.io sending and receiving a message - uploaded to <a href="https://github.com/parj/node-websocket-demo" rel="nofollow">https://github.com/parj/node-websocket-demo</a> as a reference</p> <p>Essentially two changes</p> <ol> <li><p>On Server side - changed <code>socket.on</code> to <code>socket.sockets.on</code> </p> <pre><code>var socket = io.listen(server); socket.sockets.on('connection', function(client) </code></pre></li> <li><p>On Client side - URL and port not required as it is autodetected.</p> <pre><code>var socket = io.connect(); </code></pre></li> </ol> <p>This has been tested using Express 2.5.2 and Socket.io 0.8.7</p> <p>I have amalgamated your server code with mine, would you be able to try this on the server and my <a href="https://github.com/parj/node-websocket-demo/blob/master/public/main.js" rel="nofollow">client javascript</a> and <a href="https://github.com/parj/node-websocket-demo/blob/master/public/index.html" rel="nofollow">client html</a> just to see if it is working?</p> <pre><code>var socket = io.listen(server); socket.sockets.on('connection', function(client){ var connected = true; client.on('message', function(m){ sys.log('Message received: '+m); }); client.on('disconnect', function(){ connected = false; }); var t = setInterval(function(){ if (!connected) { return; } cp.exec('/usr/bin/php /Users/crear/Projects/MandaFree/symfony api:getRemainingMessages', function(err, stdout){ if (err) { client.send('error : An error ocurred while running child process.'); } else { client.send('change : ' + stdout); } console.log('Remaining messages: ' + stdout); }); }, 3000); t(); }); </code></pre>
