How to Create a Paginated List

In order to create a paginated list, create a method on your controller that first creates a SS_List that contains all your record, then wraps it in a PaginatedList object. The PaginatedList object should also passed the SS_HTTPRequest object so it can read the current page information from the "?start=" GET var.

The PaginatedList will automatically set up query limits and read the request for information.


 * Returns a paginated list of all pages in the site.
public function PaginatedPages() {
    $list = Page::get();

    return new PaginatedList($list, $this->getRequest());

Note that the concept of "pages" used in pagination does not necessarily mean that we're dealing with Page classes, it's just a term to describe a sub-collection of the list.

There are two ways to generate pagination controls: PaginatedList::Pages() and PaginatedList::PaginationSummary(). In this example we will use PaginationSummary().

The first step is to simply list the objects in the template:


    <% loop $PaginatedPages %>
        <li><a href="$Link">$Title</a></li>
    <% end_loop %>

By default this will display 10 pages at a time. The next step is to add pagination controls below this so the user can switch between pages:


<% if $PaginatedPages.MoreThanOnePage %>
    <% if $PaginatedPages.NotFirstPage %>
        <a class="prev" href="$PaginatedPages.PrevLink">Prev</a>
    <% end_if %>
    <% loop $PaginatedPages.Pages %>
        <% if $CurrentBool %>
        <% else %>
            <% if $Link %>
                <a href="$Link">$PageNum</a>
            <% else %>
            <% end_if %>
        <% end_if %>
        <% end_loop %>
    <% if $PaginatedPages.NotLastPage %>
        <a class="next" href="$PaginatedPages.NextLink">Next</a>
    <% end_if %>
<% end_if %>

If there is more than one page, this block will render a set of pagination controls in the form [1] ... [3] [4] [5] [6] [7] ... [10].

Paginating Custom Lists

In some situations where you are generating the list yourself, the underlying list will already contain only the items that you wish to display on the current page. In this situation the automatic limiting done by PaginatedList will break the pagination. You can disable automatic limiting using the PaginatedList::setLimitItems() method when using custom lists.

$myPreLimitedList = Page::get()->limit(10);

$pages = new PaginatedList($myPreLimitedList, $this->getRequest());

Setting the limit of items

$pages = new PaginatedList(Page::get(), $this->getRequest());

If you set this limit to 0 it will disable paging entirely, effectively causing it to appear as a single page list.

Template Variables

Variable Description
$MoreThanOnePage Returns true when we have a multi-page list, restricted with a limit.
$NextLink, $PrevLink They will return blank if there's no appropriate page to go to, so $PrevLink will return blank when you're on the first page.
$CurrentPage Current page iterated on.
$TotalPages The actual (limited) list of records, use in an inner loop
$TotalItems This returns the total number of items across all pages.
$Pages Total number of pages.
$PageNum Page number, starting at 1 (within $Pages)
$Link Links to the current controller URL, setting this page as current via a GET parameter
$CurrentBool Returns true if you're currently on that page
