Yii PHP Add Pagination to my site - php

Question

I would like to add pagination to my website, but I am very new to Yii and would like some advise.
This is the page that I am looking to add pagination: https://gocar2.com/newsproducts/center
As you can see I have numerous cells for each auto news, and now I am allowing only 18 news to show on the page. I would like to add pagination here so that I can browse more news.
And this is what I tried:
newscontroller.php
<?php
use yii\data\Pagination;
class NewsproductsController extends Controller
{
public function actionCentermore()
{
$criteria = new CDbCriteria;
$criteria->addCondition("approvedStatus = '1'");
$criteria->order = 'createdDate DESC';
$product = Newsproducts::model()->findAll($criteria);
$Pagination = new Pagination([
'defaultPageSize' => 15,
'totalCount' => $product->count(),
]);
$products = $product->offset($Pagination->offset)
->limit($Pagination->limit)
->all();
$this->renderPartial('centermore',compact('products', 'Pagination'));
}
}
newsview.php will render all the top menu and banners and it will render centermore.php
$this->renderPartial('centermore', compact('products', 'Pagination'));
centermore.php (view of the news cells), I then added the LinkPager widget at the bottom.
LinkPager::widget(['Pagination' => $Pagination])
And of course, there is an error, Class LinkPager cannot be found.
Can anyone give me some advise how to solve this/implement paging?

In Yii2 pagination is usually handled via DataProvider, have a look at the:
Yii2 Guide: Data Providers, especially ActiveDataProvider:
use yii\data\ActiveDataProvider;
$query = Post::find()->where(['status' => 1]);
$provider = new ActiveDataProvider([
'query' => $query,
'pagination' => [
'pageSize' => 10,
],
'sort' => [
'defaultOrder' => [
'created_at' => SORT_DESC,
'title' => SORT_ASC,
]
],
]);
// returns an array of Post objects
$posts = $provider->getModels();
