php - Ajax POST Javascript Objects to Zend Controller and recieving -

i'm trying pass javascript objects view update controller in zend.

my json string looks :

[{"item_id":null,"parent_id":"none","depth":0,"left":"1","right":4},{"item_id":"1","parent_id":null,"depth":1,"left":2,"right":3}] 

and it's assigned variable jsonobj.

my ajax post looks :

$.ajax({             type: "post",             url: "http://dev.jp-websolutions.co.uk/cms_nishan/admin/navigation/update",             data: jsonobj,             contenttype: "application/json; charset=utf-8",             datatype: 'json',             success: function(data) {                 alert(json.stringify(data, null, 4));             },             error: function() {                 alert("failure");             }         });         return false;     }     ; 

and update controller :

public function updateaction() {          if ($this->getrequest()->isxmlhttprequest()) {             $this->_helper->layout()->disablelayout();             $this->_helper->viewrenderer->setnorender();         }          $data = $this->_request->getpost();         $result = zend_json::decode($data);         print_r($result);     } 

but cant work, if use

$result = zend_json::decode([{"item_id":null,"parent_id":"none","depth":0,"left":"1","right":4},{"item_id":"1","parent_id":null,"depth":1,"left":2,"right":3}]); 

it displays properly,

array (  [0] => array (  [item_id] =>  [parent_id] => none  [depth] => 0  [left] => 1  [right] => 4 )   [1] => array ( [item_id] => 1 [parent_id] => [depth] => 1 [left] => 2 [right] => 3 ) )  

how can work? appreciated :)

you're sending json request body, no identifier, on php side need use getrawbody() json:

$data = $this->getrequest()->getrawbody(); 

the getpost() method should used if data submitted identifier contenttype application/x-www-form-urlencoded.

also make sure javascript variable jsonobj string containing json, not object. if it's object have jsonobj = json.stringify(jsonobj).

docs zend request object

alternatively can send json identifier. change ajax to:

$.ajax({             type: "post",             url: "http://dev.jp-websolutions.co.uk/cms_nishan/admin/navigation/update",             data: {json : jsonobj},             datatype: 'json',             success: function(data) {                 alert(json.stringify(data, null, 4));             },             error: function() {                 alert("failure");             }         });         return false;     }; 

on php side, use getpost('json'):

$data = $this->_request->getpost('json');
