PHP not receiving data from XMLhttprequest

Question

Hi I am sending data to a php script like so:

function ajax(url,data,success) {
    var request = new XMLHttpRequest();
    request.open("POST", url);
    request.onreadystatechange = function(object) {
        if(request.readyState === 3) {
            success(request);
        }
    };
    request.setRequestHeader("Content-Type","application/json")
    request.send(data);
}

The data being sent is a stringifyed javascript object. The post definitely works and the object shows in the payload section in chromes dev tools. But the php script I am sending to request object is empty. The php script's content type is set to json.

If you look in your browser console, can you see the data you're trying to send in POST? — vard, Jul 20 '15 at 10:20
@frankastin, you are not completely right. It might be issue caused by poorly configured PHP. That's why I asked. — Kristian Vitozev, Jul 20 '15 at 10:29

Sounds like you're experiencing quite a well-known issue (some info here: PHP "php://input" vs $_POST)

You should be able to access the data with file_get_contents('php://input')

Cheers, that did it. I presume jQuery's ajax converts it across to url-form vars before sending. – frank astin Jul 20 '15 at 10:27
You're welcome. It's quite a common issue - I've had the same problem before and hence how I was able to guess that's what you were having! :D – nealio82 Jul 20 '15 at 11:41
