Knockout and AJAX post request PHP

Question

I am attempting to get our knockout form to submit to a php script and am getting undefinedIndex errors. I am pretty sure it is the way we are sending the data over in our ajax function.

Here is the ajax:

        $.ajax({
        url: '/orders/add',
        type: 'post',
        data: {payload:ko.toJSON(allModel)},
        contentType: 'application/json',
        success: function (result) {
            alert(result);
        }
    });

Here is the PHP (we use laravel)

 return json_decode($_POST["payload"]);

Pete is correct. You need to use just one data field. If you want a variable, define it before the $.ajax post

var dataPayload = ko.toJSON(allModel);
$.ajax({
    url: '/orders/add',
    type: 'post',
    data: {payload: dataPayload},
    contentType: 'application/json',
    success: function (result) {
        alert(result);
    }
});
