receive $_POST variables from jquery ajax request

I am making an ajax request that looks like 

 var object = JSON.stringify(object);
// var url = "http://"+baseURL +"/"+endpoint;

$.ajax({
    contentType: "application/json",
    dataType: 'json',
    type:type,
    data:object,
    url:endpoint,
    success:function(data){
        if (typeof callback == "function"){
            alert(data);
        }
    },

    error: function (xhr, textStatus, errorThrown) {
        console.log(xhr.statusText);
        console.log(xhr.responseText);
        console.log(xhr.status);
        console.log(errorThrown);
    }
});

where var=object is a stringified json objectby the time it makes it into the ajax request. On the php side, I am trying to catch the variables by doing 

<?php
   echo ($_POST['object']);
   exit;
?>

and my success call back function alerts the data as "null". What am I doing wrong?

Thanks, alex

Skip the json.stringify you don't want the data as json text in the post body. To populate the post array it needs to be sent as application/x-www-form-urlencoded. To do this in jquery just set the data attribute to an object instead of a string.

// remove this.... var object = JSON.stringify(object);
// var url = "http://"+baseURL +"/"+endpoint;

$.ajax({
    dataType: 'json',
    type:"POST",  // <--- Should be post
    data:object,
    url:endpoint,
    success:function(data){
        if (typeof callback == "function"){
            alert(data);
        }
    },

    error: function (xhr, textStatus, errorThrown) {
        console.log(xhr.statusText);
        console.log(xhr.responseText);
        console.log(xhr.status);
        console.log(errorThrown);
    }
});

It is possible to get the data as you are sending it currently but you have to go through a little more work on the PHP side. 

$_POST = json_decode(file_get_contents("php://input"),true);
