RUN function on WIDGET




public function run()

    {

        $usuario = Usuario::model()->getUsuarioSession();

        if(isset($_POST['ajax']) && $_POST['ajax']==='evento-form')

                {

                        echo CActiveForm::validate($this->model);

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

                }   

        if(isset($_POST['Evento']))

        {

            

            // collects user input data

            $this->model->attributes=$_POST['Evento'];

            // validates user input and redirect to previous page if validated

            $fechaHoy = date('Y-m-d H:i:s');

            $this->model->fechaCreacion = new CDbExpression("NOW()");

            $fechaHoraDeEvento = $this->fechaEntera . date('H:i:s');

            $this->model->fechahoraDelEvento = new CDbExpression("NOW()");//OBTENER DEL FORMULARIO

            

            if($this->model->validate()) {

                $this->model->fueNotificado = 1;

                $this->model->save();

                $participacion = Participacion::model()->findAll('EVENTO_idEVENTO = :idEvento', array('idEvento' => $this->model->getPrimaryKey()));

                if ($participacion == NULL)

                {

                    $participacion = new Participacion();

                    $participacion->USUARIO_idUSUARIO = $usuario->id;

                    $participacion->EVENTO_idEVENTO = $this->model->getPrimaryKey();

                    /*if ($this->idtipo == 14){

                        $this->model->COMISION_idCOMISION;

                    }

                    if ($this->idtipo == 22){

                    $participacion->tipo_participacion = 17;

                    $participacion->descripcion = 'descripcion';

                    $participacion->asistencia = 0;

                    $participacion->aprobado = 1;

                    $participacion->save();

                }

            }

            //FUE AÑADIDO

            return;

        }

        // displays the form

        $this->render("crearEventoThumb",array(

            'model' => $this->model,

            'arrayEventosPosibles' => $this->tiposEvento,

            'fecha'=> $this->fechaEntera));

        }



model save works perfectly, the thing is wether use ajaxsubmitbutton or tbButton, refreshes my whole page.

please help in this one!

ive tried everything so far (i realize the ajaxsubmitbutton aims to other action, but doesn’t make a change anyways… the widget is a selfbuild widget, not an extension,

cheers
