problem trying catch error messages , output using ajax. in registercontroller having following function:

public function ajaxaction() {     if (!$this->request->ispost()) {         return $this->redirect()->toroute(null,             array( 'controller' => 'index'             )         );     }      $form = $this->getservicelocator()->get('registerform');     $form->setinputfilter(new registerfilter($this->getservicelocator()));       $post = $this->request->getpost();     $form->setdata($post);     $response   = $this->getresponse();     $hello = 1;     if (!$form->isvalid()){         // email invalid; print reasons         $json= $form->getmessages();         $response->setcontent(\zend\json\json::encode($json));     }     return $response; } 

and jquery file:

$( document ).ready(function() {          var urlform = "register/ajax";     $("#btnregister").click( function() {         $("#register").submit( function() {            return false;             });         $.ajax({             url: urlform,             type: 'post',             datatype: 'json',             async: true,             data: $(".form-signin").serialize(),             success: function (data) {                 $("#rcheck").text(data);                 console.log(data);             },             error: function (data) {                 $("#rcheck").text(data);                 console.log(data);             }         });      }); }); 

in console got https://imagizer.imageshack.us/v2/558x205q90/661/uc09da.png , in div id #rcheck getting [object][object].

from image provided error messages correctly returned. error trying write directly object div.

you should have seached how read object javascript. try code :

success: function (data) {             data.foreach(function(datum) {                object.keys(datum).foreach(function (key) {                 $('<p>'+obj[key]+'</p>').appendto('#rcheck');                 });             });             console.log(data);         }, 

or may within ajaxaction :

$messages = array(); $errors = $form->getmessages(); foreach($errors $key=>$row) {     if (!empty($row) && $key != 'submit') {         foreach($row $keyer => $rower)         {             $messages[$key][] = $rower;             }     } } if (!empty($messages)){  $response->setcontent(\zend\json\json::encode($messages)); } return $response;        

here's post on how use zend\form ajax validation.

hope help.
