POST data from knockout.js to CakePHP controller - php

Question

I'm posting data from a knockout.js page to a controller in cakephp and it says the data was successfully posted, however, my controller doesn't seem to be responding and I don't get an alert back...not even a null response. I even checked the network tab in chrome and it shows the correct data being POSTED
Here's the data being posted from my knockout viewmodel file
var JSON_order = JSON.stringify({"orderInfo":[{"itemNumber":"1","quantity":"1","price":1.00,"productName":"test"}]});
$.post("/orders/submit_order", JSON_order,
function(data){
alert(data.check); //alert doesn't appear
}, "json");
Here's my controller
function submit_order(){
$this->layout = false;
$this->autoRender = false;
if ($this->request->is('post')) {
$order = $this->request->data;
$order = json_decode($order, true);
$finalize_order = new submit;
$finalize_order->display_submitted_order_success($order);
}
}
Here's the code for display_submitted_order_success (I also tried this on a php file outside of CakePHP but it didn't work either)
function display_submitted_order_success($order = null){
$this->layout = false;
$this->autoRender = false;
//I'm just trying to display the order as-is so that I know it's even being posted to begin with
echo json_encode(array("check" => "success","order_num" => $order)); //the values passed the price check, display the result
}

You have to assign the value of JSON_order to a var:
var JSON_order = JSON.stringify({"orderInfo":[{"itemNumber":"1","quantity":"1","price":1.00,"productName":"test"}]});
$.post("/orders/submit_order", {order:JSON_order},
function(data){
alert(data.check); //alert doesn't appear
}, "json");
So that your controller would receive it like this:
$data['order'] = '{"orderInfo":[{"itemNumber":"1","quantity":"1","price":1,"productName":"test"}]}'
