Using Websockets in codeigniter?

Hey guys, it's me again.

I still have the notification issue, but I asked my professors, and they said the best solution is indeed Websockets. I found a great library for websockets in codeigniter here, and it does work, but I can't seem to figure out how to send messages from the modal to a view. I did the simple setup with the "php vendor/takielias/codeigniter-websocket/install.php --app_path=application" command, and I was able to have to 'clients' talk to one another. I was even about to get one of them to talk to my view php file.

Now I just need to get the modal to talk to the view. I tried adding this to the top of the modal file:

Code:

defined('BASEPATH') OR exit('No direct script access allowed');
require('vendor/autoload.php');

use WebSocket\Client;

And then I try to log in in the modal's constructor with this:

Code:

                $this->client = new Client('ws://0.0.0.0:8282');

                $this->client->send(json_encode(array('user_id' => 1, 'message' => null)));
                $this->client->send(json_encode(array('user_id' => 1, 'message' => 'Super cool message to myself!')));

The readme states that the first message is necessary for validation of the connection.

Despite this, I never receive the message on the view file. The socket code in my view is: 

Code:

var conn = new WebSocket('ws://localhost:8282');
    var client = {
        user_id: 1,
        recipient_id: null,
        type: 'socket',
        token: null,
        message: null
    };

    conn.onopen = function (e) {
        conn.send(JSON.stringify(client));
        $('#messages').append('<font color="green">Successfully connected as user ' + client.user_id + '</font><br>');
    };

    conn.onmessage = function (e) {
        var data = JSON.parse(e.data);
        if (data.message) {
            $('#messages').append(data.user_id + ' : ' + data.message + '<br>');
        }
        if (data.type === 'token') {
            $('#token').html('JWT Token : ' + data.token);
        }
    };

Let me guess, its the ports? I played around with them to no avail. Any ideas?

Turns out, you can send the messages from the CONTROLLER, but not the model! I made the apropriot changes to my code, and it works! Just one problem, though...

It isn't working on my AWS instance. Is there some reason why? Permissions, maybe?
