How do I send PHP POST and FILES data to an AJAX URL call when they are not from an HTML form?

Question

I have a PHP page with $_POST and $_FILES data filled in. The POST data was obtained not from a traditional HTML form, but between multiple pages.

For example, the POST data is a number of things:

$_POST["username"]
$_POST["password"]
$_FILES
etc.

The question is, how do I send this POST data off to an AJAX call within the page?

I know with a form it's something like this:

$.ajax({
   type: 'post',
   url: 'post.php',
   data: $('form').serialize(),
   success: function () {
     alert('form was submitted');
   }
 });

But what about directly from PHP's POST data?

I'm confused on what you're trying to do. AJAX is a client side concept of calling server side. Not the other way around. You cannot use Ajax server side in PHP code. — Canolyb1, Sep 20 '17 at 19:53
Sorry for the confusion, I have slightly edited the post. The POST data is passed to second PHP page that loads and will have a realtime progress bar start automatically via Ajax calls. I can tell from the comments that I may have designed this incorrectly. — Ethan Allen, Sep 20 '17 at 19:57
Do this: `data: { userid: "joe smoe", firstName:"joe"}` you can pass your values as parameters key: value... — brso05, Sep 20 '17 at 19:57

You can use WebSocket or EventSource and possibly ServiceWorker to stream data from server to client. For example, see How to read and echo file size of uploaded file being written at server in real time without blocking at both server and client? where the requirement is to stream the progress of bytes of uploaded file being written to file at server by php in real time without blocking.
