jQuery/PHP can't decode json data

Pretty much I feel like I've tried everything. the data is write and sends out {"beans":1337,"uid","five"}, but I can't get the php code working. I'm trying to have the alert(data.response) return 1337, but right now I just get a blank alert statement

HTML Code:

---

var data = {};
data.beans = 1337;
data.uid = 'five';
var dataString = JSON.stringify(data);

$.ajax({
        type:'GET',
        url:'http://mvmdesign.org/other/Beacon/ws/user_data.php',
        dataType:'jsonp',
        data:{data:dataString},
        contentType:'application/json',
        success: function(data) {
                alert(data.response);
        }
});

---

I've also tried:

HTML Code:

---

$.getJSON('http://mvmdesign.org/other/Beacon/ws/user_data.php?data='+dataString+'&callback=?',function(data) {
        alert(data.response);
});

---

PHP Code:

---

$res = json_decode($_GET['data'],true);
$beans = $res['beans'];
echo $_GET['callback'] . '({"response" : "' . $beans . '"});'; 


---

EDIT: Bad first response....your PHP code is the problem.

You don't need to use json_decode() on the $_GET superglobal - they're all separate parameters anyway.

PHP Code:

---

$beans = $_GET['beans'];
echo $_GET['callback'] . '({"response" : "' . $beans . '"});'; 


---

That doesn't work

HTML Code:

---

$.getJSON('http://mvmdesign.org/other/Beacon/ws/user_data.php?data='+dataString+'&callback=?',function(data) {
        alert(data.response);
});

---

with:

PHP Code:

---

echo $_GET['callback'] . '({"response" : "' . $_GET['data'] . '"});'; 


---

alerts {"beans":1337,"uid":6}

I just can't figure out how to extract beans for example out of $_GET['data']
json_decode doesn't work, nor does $_GET['data']->{"beans"}

It's not adding up for me

It might be useful to dump what your getting to the PHP error log to find out exactly what is in there and its structure, e.g.:

PHP Code:

---

$res = json_decode($_GET['data'], true);
error_log("GET data:\n" . print_r($res, true])); 


---

Then check your PHP error log to find out what exactly was received.

yes, also you could use Firebug to see what is the response.
it might be just a simple notice that can break the JS

found the problem

PHP Code:

---

$res = json_decode(stripslashes($_GET['data']),true);
echo $res['uid']; 


---

PHP was interpreting the the data as

HTML Code:

---

{\"beans\":1337,\"uid\":5}

---

So just the stripslashes method was missing

Sounds as if your PHP config has the now-deprecated magic_quotes_gpc "feature" turned on. You might want to consider either turning it off if you can, or else negating it's effects before using any get, post, or cookie data.
