i add a boton ajaxsubmit which send me to my controller which in turn makes a render to another view. protected/controller/ajaxController




<?php


class AjaxController extends Controller {


    public function actionTema() {

        $model = new Temas();

        $this->renderPartial('/theme/_formAjax', array('model' => $model));

        // $this->renderPartial('/theme/_form', array('model' => $model));

        Yii::app()->end();

    }


    public function actionCrear() {

        $model = new Temas;


        if (isset($_POST['Temas'])) {

            $model->attributes = $_POST['Temas'];

// $model->attributes =Yii::app()->user->getId();

            if ($model->validate()) {


                $nombre = '=?UTF-8?B?' . base64_encode($model->nombre) . '?=';

                $descripcion = '=?UTF-8?B?' . base64_encode($model->descripcion) . '?=';

                $fecha = '=?UTF-8?B?' . base64_encode($model->fecha) . '?=';

                $usuarios_id = '=?UTF-8?B?' . base64_encode($model->usuarios_id) . '?=';

                if($model->save()){

                 //   exit(json_encode(array('result'=>'success','msg'=>'Registro exitoso')));

                     $this->renderPartial('/theme/admin', array('model' => $model),false,true);

                }else{

                    exit(json_encode(array('result'=>'error','msg'=>CHtml::errorSummary($model))));

                }

            }

        }

        $this->renderPartial('/theme/admin', array('model' => $model),false,true);

         //exit(json_encode(array('result'=>'error','msg'=>'No input data has been passed.')));

    }


}




and finally my form view, where the user has to fill some fields and to make a record, the record button is also a ajaxsubmit which if it meets the feature saves in the database, otherwise it sends errors, the way I did save and send the error but the botton does not work as ajax me as I redericciona to another view and stays where it should not.

/protected/views/theme/_formAjax.php




<div class="form">

    <?php

    $form = $this->beginWidget('CActiveForm',array(

        'id'=>'user-form',

        'enableAjaxValidation'=>true,

        'action'=>$this->createUrl('ajax/Crear'),

        'enableClientValidation'=>true,)

            );

    ?>




    <p class="note">Campos con <span class="required">*</span> son requeridos.</p>


    <?php echo CHtml::errorSummary($model); ?>


    <div class="row">

        <?php echo $form->labelEx($model, 'nombre'); ?>

        <?php echo $form->textField($model, 'nombre', array('size' => 80, 'maxlength' => 128)); ?>

        <?php echo $form->error($model, 'nombre'); ?>

    </div>


    <div class="row">

        <?php echo $form->hiddenField($model, 'usuarios_id', array('readonly' => true)); ?>

    </div>




    <div class="row buttons">

                         $("#user-form")[0].reset();

                        }

                         else{

                        $.each(data, function(key, val) {

                        $("#user-form #"+key+"_em_").text(val);                                                    

                        $("#user-form #"+key+"_em_").show();

                        });

                        }       

                    }',                    

                     

                     ),array('id'=>'mybtn','class'=>'class1 class2'));

        ?>
