How to implement EventSource on Codeignigter app?

You sent it how?
I have not received anything except the link to a GitHub page which did not work.

But it sounds like you're making progress. Good.

I sent it as a private message, but I suppose it doesn't matter any more! Now I just need to figure out how to send the form data to the controller via fetch. I am calling the controller, but the data isn't getting passed...

You've been a MAJOR help, though!
