Jquery ajax json response not showing -

hey code follows:

js:

$.ajax({     type: "post",     url: "master.php",     contenttype: "application/json; charset=utf-8",     data: { "called": "reg",             "fname": $("#fname").val()                                   },     datatype: "json",     success: function(data, responsetext, textstatus){         response = jquery.parsejson(data);         console.log("good: " + response);         console.log("good3: " + textstatus);         console.log("good3: " + responsetext);     },     error: function(xmlhttprequest, textstatus, errorthrown){         console.log("error: " + textstatus);     } }); 

and master.php has:

<?php $called = $_post['called'];  if ($called == 'reg') {     $json = array('good' => 'the value here');     header("content-type: application/json", true);      echo json_encode($json); } ?> 

the console output this:

good: null form.php:102

good3: [object object] form.php:103

good3: success

what missing?

you're using post method, accessing $_get array in php script
