seeing the data that we input in form in yii2

I'm a newbie in yii2.

I have generated this code in gii using form generator

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

/* @var $this yii\web\View */
/* @var $model app\models\Publikasi */
/* @var $form ActiveForm */
?>
<div class="publikasi">

    <?php $form = ActiveForm::begin(); ?>


        <?= $form->field($model, 'NIP') ?>
        <?= $form->field($model, 'Tanggal') ?>
        <?= $form->field($model, 'StatusPenulis') ?>
        <?= $form->field($model, 'JudulPenelitian') ?>
        <?= $form->field($model, 'BidangKajian') ?>
        <?= $form->field($model, 'NamaJurnal') ?>
        <?= $form->field($model, 'StatusJurnal') ?>

        <div class="form-group">
            <?= Html::submitButton(Yii::t('app', 'Submit'), ['class' => 'btn btn-primary']) ?>
        </div>


    <?php ActiveForm::end(); ?>

</div><!-- publikasi -->

when I run this code, the result come to the same page. my question is how can I see the data that i input to that form?
