Yii is a popular PHP web application framework that provides built-in support for pagination. Here are the steps to create pagination in Yii:

  1. First, you need to set up a data provider for the model that you want to paginate. A data provider is responsible for fetching the data from the database and returning it in a format that can be used for pagination. Here is an example:
1
2
3
4
5
6
$dataProvider = new ActiveDataProvider([
    'query' => Post::find(),
    'pagination' => [
        'pageSize' => 10,
    ],
]);


In this example, we are creating a new ActiveDataProvider object that fetches data from the Post model using the find() method. We have also set the page size to 10, which means that each page will display 10 records.

  1. Next, you need to create a ListView widget and pass the data provider to it. The ListView widget is responsible for rendering the paginated data. Here is an example:
1
2
3
4
5
6
<?= ListView::widget([
    'dataProvider' => $dataProvider,
    'itemView' => '_post',
    'layout' => "{items}
{pager}",
]); ?>


In this example, we are creating a ListView widget and passing the $dataProvider object to it. We have also set the itemView property to _post, which is the name of the view file that will be used to render each item. Finally, we have set the layout property to {items} {pager}, which means that the items will be rendered first, followed by the pager.

  1. That's it! Yii will automatically handle pagination for you, and the pager will be rendered at the bottom of the page. If you want to customize the pager, you can use the Pager widget and pass it to the layout property of the ListView widget. Here is an example:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
<?= ListView::widget([
    'dataProvider' => $dataProvider,
    'itemView' => '_post',
    'layout' => "{items}
{pager}",
    'pager' => [
        'class' => 'yiiwidgetsLinkPager',
        'options' => [
            'class' => 'pagination',
        ],
        'prevPageLabel' => '&laquo;',
        'nextPageLabel' => '&raquo;',
    ],
]); ?>


In this example, we have created a custom pager using the LinkPager widget. We have also set the prevPageLabel and nextPageLabel properties to &laquo; and &raquo;, respectively, to use arrows instead of the default text labels.
