Data::Pageset::Render - Subclass of Data::Pageset that generates html, text, etc. for page navigation
Data::Pageset
### In the Controller part of you MVC # Create the pager as you would normally with Data::Pageset use Data::Pageset::Render; my $pager = Data::Pageset::Render->new( { total_entries => 100, entries_per_page => 10, current_page => 1, pages_per_set => 5, mode => 'slider', link_format => '<a href="q?page=%p">%a</a>', } ); ### In the view part of your MVC my $text = $pager->html; # $text is html "<< 1 ... 3 4 5 6 7 ... 10 >>" with appropriate links ### Or As part of larger framework # In a TT template: [% pager.html() %] # In a Mason template: <% $pager->html() %> ### For a bit more control over the appearence of the current page: my $pager = Data::Pageset::Render->new( { total_entries => 100, entries_per_page => 10, current_page => 1, pages_per_set => 5, mode => 'slider', link_format => '<a href="q?page=%p">%a</a>', current_page_format => '[%a]', } ); my $text = $pager->html(); # $text is html "<< 1 ... 3 4 [5] 6 7 ... 10 >>" with appropriate links =head1 DESCRIPTION
Data::Pageset::Render inherits from Data::Pageset and adds the html method which renders a pager, complete with links, in html. The constructor take two additional optional configuration parameters, and all of Data::Pagesets methods continue to function as normal.
Data::Pageset::Render
Data::Pageset::Render adds the link_format and current_page_format configuration options to Data::Pageset. See the html method for more information on these options.
link_format
current_page_format
html
my $text = $pager->html(); my $text = $pager->html( '<a href="q?page=%p">%a</a>' ); my $text = $pager->html( '<a href="q?page=%p">%a</a>', '[%a]' );
Produces the text necessary to implement page navigation. Most often this will be used to create a links to pages within your web app. The two special character codes %p and %a will be substituted with the page number and the link text, respectively. %a will usually also be the page number, but sometimes it could be "<<", ">>", or "...".
%p
%a
Rather than code this in TT or Mason or (even worse) by hand, Data::Pageset::Render replaces all of this:
## TT template: [% IF pager.current_page > 1 %] <a href="display?page=[% pager.current_page - 1 %]"><<</a> [% END %] [% FOREACH num = [pager.first_page .. pager.last_page] %] [% IF num == pager.current_page %][[% num %]] [% ELSE %]<a href="display?page=[% num %]">[[% num %]]</a>[% END %] [% END %] [% IF pager.current_page < pager.last_page %] <a href="display?page=[% pager.last_page %]">>></a> [% END %]
with this:
[% pager.html() %]
And you get even more goodness from Data::Pageset limiting the pages displayed to something reasonable if you are dealing with a large number of pages.
$pager->link_format( '<a href="q?page=%p">%a</a>' );
Accessor for the link_format setting.
$pager->current_page_format->current_page_format => '[%a]' );
Accessor for the current_page_format setting.
In this release, there is limited ability to customize the page navigation. I plan to add the ability to customize the following:
Option to not display the first/last pages if they aren't part of current page set
Option to not display the link to the prior/next page set (assuming it exists)
Ability to customize the look of "move back/forward" links (currently only << and >> are supported) or turn them off completely
Ability to customize the look of the prior/next page sets (currently only "..." is supported)
Ability to specify the separators between links (ie, enable "1 | 2 | 3 | 4" type pagers)
Add class to particular page link. Show << without a link if on page 1, etc.
This module is a work in progress and suggestions are welcome.
