    text
    copied!<p>I want to use node.js and socket.io to show how many users are currently viewing a certain page on my website, by sending a message with the page address (i.e /homepage or /events) to the node.js server, then read/write a file with the address name (i.e. homepage.txt, or events.txt), get the current count and add 1 then write it back to the file, then do the same on disconnect but instead remove 1 and save it.</p> <p>Here is the code I have so far, currently excluding the fs functions for testing, also the server file and client file are in the same directory</p> <p>Client: </p> <pre><code>&lt;?php $url = $_SERVER["REQUEST_URI"]; ?&gt; &lt;body style="overflow: hidden;" /&gt; &lt;script type="text/javascript" src="jquery.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="/node_modules/socket.io/lib/socket.io.js"&gt;&lt;/script&gt; &lt;script&gt; var socket = io.connect('http://localhost:5000'); socket.on('connected', function (data) { $("#log").append('Connected!&lt;br /&gt;'); $("#log").append(data + "&lt;br /&gt;"); socket.emit('viewing', { page: '&lt;?php echo $url; ?&gt;' }); socket.on('disconnected', function(data) { $("#log").append("User Disconnected" + "&lt;br /&gt;"); }); }); &lt;/script&gt; &lt;div id='log' style='height: 100%; border: 1px solid black;'&gt;&lt;/div&gt; </code></pre> <p>Server: </p> <pre><code>var io = require('socket.io').listen(5000); var connected_users = 0; io.sockets.on('connection', function(socket) { connected_users++; console.log("User Connected!"); socket.emit("connected", { message: "Users Online: " + connected_users + "!" }); socket.on('viewing', function(data){ console.log("User Is Viewing: " + data); }); socket.on('disconnect', function(){ connected_users--; console.log("User Disconnected!"); socket.emit("disconnected", { message: "Users Online: " + connected_users + "!" }); }); }); </code></pre> <p>but for some reason this doesn't seem to be working, all the server says is "info - socket.io started" and nothing else when a user connects to the client page</p> <p>any hints/ideas on what I might be doing wrong.</p> <p>thank-you in advance -- Vinny</p>
