        <input name="preview" class="form-control" id="preview" placeholder="Preview">

        <?= \yii\helpers\Html::submitButton('Save', ['class' => 'btn btn-primary']) ?>
    </div>
<?php \yii\widgets\ActiveForm::end() ?>

$model = new LinkPreviewModel();
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
    $model->save();
}

// or the short version 

$linkPreviewId = LinkPreviewModel::saveAndGetId(Yii::$app->request->post());
