DESCRIPTION

Mojolicious::Plugin::Pager is a Mojolicious plugin for creating paged navigation, without getting in the way. There are other plugins which ship with complete markup, but this is often not the markup that you want.

Note that this plugin is currently EXPERIMENTAL.

HELPERS

  $bytestream = $c->pager_link(\%page, @args);
  $bytestream = $c->pager_link(\%page, @args, sub { int(rand 100) });

Takes a %page hash and creates an anchor using "link_to" in Mojolicious::Controller. @args is passed on, without modification, to link_to(). The anchor generated has some classes added.

See "pages_for" for detail about %page.

Examples output:

  <a href="?page=2" class="prev" rel="prev">12</a>
  <a href="?page=1" class="first">1</a>
  <a href="?page=2" class="page">2</a>
  <a href="?page=3" class="active">3</a>
  <a href="?page=4" class="page">4</a>
  <a href="?page=5" class="page">5</a>
  <a href="?page=6" class="last">6</a>
  <a href="?page=3" class="next" rel="next">3</a>

pages_for

  @pages = $self->pages_for($total_pages);
  @pages = $self->pages_for(\%args)
  @pages = $self->pages_for;

Returns a list of %page hash-refs, that can be passed on to "pager_link".

Example %page:

  {
    n       => 2,    # page number
    current => 1,    # if page number matches "page" query parameter
    first   => 1,    # if this is the first page
    last    => 1,    # if this is the last page
    next    => 1,    # if this is last, that brings you to the next page
    prev    => 1,    # if this is first, that brings you to the previous page
  }

%args can contain:

  • current

    Default to the "page" query param or "1".

  • items_per_page

    Only useful unless total is specified. Default to 20.

  • size

    The max number of pages to show in the pagination. Default to 8 + "Previous" and "Next" links.

  • total

    The total number of pages. Default to "1" or...

      $total = $args->{total_items} / $args->{items_per_page}
      $total = $c->stash('total_items') / $c->stash('items_per_page')

METHODS

register

  $app->plugin(pager => \%config);

Used to register this plugin and the "HELPERS" above. %config can be:

  • classes

    Used to set default class names, used by "pager_link".

    Default:

      {
        current => "active",
        first   => "first",
        last    => "last",
        next    => "next",
        prev    => "prev",
        normal  => "page",
      }
  • param_name

    The query parameter that will be looked up to figure out which page you are on. Can also be set in "stash" in Mojolicious::Controller on each request under the name "page_param_name".

    Default: "page"
