Can’t get $_POST data from jQuery $.post calls

[kam]

Hi,
I know this is probably going to be something that I missed. But I have been doing jQuery .post calls for a year now but can’t get this to work. Basically I’m sending and age to the server and checking what sports level it should be assigned to. Simple – No? NO! I can see from the headers that I am sending the JSON data to the server but when it gets there the $_POST call comes back as NULL.
Here’s the code

JavaScript:

   function AgeInput(input) {

var data = "{ "age" : "+input.val()+" }";

$.post("ajax/getLevel.php", data, function(data) {

alert("Back from server with "+data);

});

}

getLevel.php
require_once(“../includes/dbConnect.php”);

ob_start();

$return_arr = array();



$age = $_POST;

$ageInt = intval($_POST);



$return_arr = $age;

$return_arr = $ageInt;



echo json_encode($return_arr);

?>

I’ve cut it down to try and find the issue.
My Header Post headings play out as:

Parametersapplication/x-www-form-urlencoded

{ "age" : 9 }

JSON

age	9

Source

{ "age" : 9 }

but my Header Response is

{"age1":null,"age2":0}

Anybody know why I am getting NULL for my $_POST call?? (Yeah, it’s probably something stupidly simple)

Thanks,
Kevin
