Socket.io : "cannot Read Property 'emit' Of Undefined"

So I'm currently developping my website using socket.io. Today, while I was implementing the sockets, I got a nice little error 'Cannot read property 'emit' of undefined' I can not

Solution 1:

Client Code:

Change

// Connection established
    socket.on('connect', function(socket) {

to

// Connection established
    socket.on('connect', function(data) {

final:

// Connection established
    socket.on('connect', function(data) {
        $('.connect_error').hide();
        $('.connected').show();
       console.log(data);
       socket.emit('create_socket', '<?= $port; ?>');
    });

Previously, you where overwriting the socket object.
