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

$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 read-only 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 getLimit ( )

The links for navigational purpose. The array keys specify the purpose of the links (e.g. LINK_FIRST), and the array values are the corresponding URLs.

public array getLinks ( $absolute false )
$offset public read-only 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 getOffset ( )
$page public property

The zero-based current page number.

public integer getPage ( $recalculate false )
public void setPage ( $value, $validatePage false )
$pageCount public read-only property

Number of pages

$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 getPageSize ( )
public void setPageSize ( $value, $validatePageSize false )
$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 = [150]
$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 $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 $route null
$totalCount public property

Total number of items.

public integer|null $totalCount null
$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

createUrl() public method

Creates the URL suitable for pagination with the specified page number.

This method is mainly called by pagers when creating URLs used to perform pagination.

See also:

public string createUrl ( $page, $pageSize null, $absolute false )
$page integer

The zero-based page number that the URL should point to.

$pageSize integer

The number of items on each page. If not set, the value of $pageSize will be used.

$absolute boolean

Whether to create an absolute URL. Defaults to false.

return string

The created URL

getLimit() public method

public integer getLimit ( )
return integer

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.

getLinks() public method

Returns a whole set of links for navigating to the first, last, next and previous pages.

public array getLinks ( $absolute false )
$absolute boolean

Whether the generated URLs should be absolute.

return array

The links for navigational purpose. The array keys specify the purpose of the links (e.g. LINK_FIRST), and the array values are the corresponding URLs.

getOffset() public method

public integer getOffset ( )
return integer

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.

getPage() public method

Returns the zero-based current page number.

public integer getPage ( $recalculate false )
$recalculate boolean

Whether to recalculate the current page based on the page size and item count.

return integer

The zero-based current page number.

getPageCount() public method

public integer getPageCount ( )
return integer

Number of pages

getPageSize() public method

Returns the number of items per page.

By default, this method will try to determine the page size by $pageSizeParam in $params. If the page size cannot be determined this way, $defaultPageSize will be returned.

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.

getQueryParam() protected method

Returns the value of the specified query parameter.

This method returns the named parameter value from $params. Null is returned if the value does not exist.

protected string getQueryParam ( $name, $defaultValue null )
$name string

The parameter name

$defaultValue string

The value to be returned when the specified parameter does not exist in $params.

return string

The parameter value

setPage() public method

Sets the current page number.

public void setPage ( $value, $validatePage false )
$value integer

The zero-based index of the current page.

$validatePage boolean

Whether to validate the page number. Note that in order to validate the page number, both $validatePage and this parameter must be true.

setPageSize() public method

public void setPageSize ( $value, $validatePageSize false )
$value integer

The number of items per page.

$validatePageSize boolean

Whether to validate page size.
