 // in your controller set a action that responds with the data you would like to 

    // add in your field

    public function actionValue()


        $user = User::model()->findByPk(1);

        echo $user->name;



    // input field

    <?php echo CHtml::textField('username', '', ['id' => 'username']); ?>

    // make sure jquery is loaded 

    <script type="text/javascript">

        $(function() {

            $('#username').on('keyup', function() {

                $('#username').load('<?php echo $this->createUrl("site/value") ?>');
