Pagination represents information relevant to pagination of data items.

When data needs to be rendered in multiple pages, Pagination can be used to represent information such as total item count, page size, current page, etc. These information can be passed to pagers to render pagination buttons or links.

The following example shows how to create a pagination object and feed it to a pager.

Controller action:

public function actionIndex()
{
    $query = Article::find()->where(['status' => 1]);
    $countQuery = clone $query;
    $pages = new Pagination(['totalCount' => $countQuery->count()]);
    $models = $query->offset($pages->offset)
        ->limit($pages->limit)
        ->all();

    return $this->render('index', [
         'models' => $models,
         'pages' => $pages,
    ]);
}

View:

foreach ($models as $model) {
    // display $model here
}

// display pagination
echo LinkPager::widget([
    'pagination' => $pages,
]);

For more details and usage information on Pagination, see the guide article on pagination.

Property Details

Hide inherited properties

$defaultPageSize public property

The default page size. This property will be returned by $pageSize when page size cannot be determined by $pageSizeParam from $params.

$forcePageParam public property

Whether to always have the page parameter in the URL created by createUrl(). If false and $page is 0, the page parameter will not be put in the URL.

public boolean $forcePageParam true
$limit public property

The limit of the data. This may be used to set the LIMIT value for a SQL statement for fetching the current page of data. Note that if the page size is infinite, a value -1 will be returned.

public integer $limit null
$offset public property

The offset of the data. This may be used to set the OFFSET value for a SQL statement for fetching the current page of data.

public integer $offset null
$page public property

The zero-based current page number.

public integer $page null
$pageCount public property

Number of pages.

public integer $pageCount null
$pageParam public property

Name of the parameter storing the current page index.

See also $params.

public string $pageParam 'page'
$pageSize public property

The number of items per page. If it is less than 1, it means the page size is infinite, and thus a single page contains all items.

public integer $pageSize null
$pageSizeLimit public property

The page size limits. The first array element stands for the minimal page size, and the second the maximal page size. If this is false, it means $pageSize should always return the value of $defaultPageSize.

public array|false $pageSizeLimit = [
    
1,
    
50,
]
$pageSizeParam public property

Name of the parameter storing the page size.

See also $params.

public string $pageSizeParam 'per-page'
$params public property

Parameters (name => value) that should be used to obtain the current page number and to create new pagination URLs. If not set, all parameters from $_GET will be used instead.

In order to add hash to all links use array_merge($_GET, ['#' => 'my-hash']).

The array element indexed by $pageParam is considered to be the current page number (defaults to 0); while the element indexed by $pageSizeParam is treated as the page size (defaults to $defaultPageSize).

public array|null $params null
$route public property

The route of the controller action for displaying the paged contents. If not set, it means using the currently requested route.

public string|null $route null
$totalCount public property

Total number of items.

public integer $totalCount 0
$urlManager public property

The URL manager used for creating pagination URLs. If not set, the "urlManager" application component will be used.

$validatePage public property

Whether to check if $page is within valid range. When this property is true, the value of $page will always be between 0 and ($pageCount-1). Because $pageCount relies on the correct value of $totalCount which may not be available in some cases (e.g. MongoDB), you may want to set this property to be false to disable the page number validation. By doing so, $page will return the value indexed by $pageParam in $params.

public boolean $validatePage true

Method Details

__call() public method

Defined in: yii\base\BaseObject::__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

}

            
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call init().

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
public void __construct ( $config = [] )
$config array

Name-value pairs that will be used to initialize the object properties

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}

            
__get() public method

Defined in: yii\base\BaseObject::__get()

}

            
__isset() public method

Defined in: yii\base\BaseObject::__isset()

Checks if a property is set, i.e. defined and not null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

public boolean __isset ( $name )
$name string

    return false;
}

            
__set() public method

Defined in: yii\base\BaseObject::__set()

}

            
__unset() public method

Defined in: yii\base\BaseObject::__unset()

See also $pageSizeLimit.

public integer getPageSize ( )
return integer

The number of items per page. If it is less than 1, it means the page size is infinite, and thus a single page contains all items.
