NAME
Data::Pageset::Render - Subclass of `Data::Pageset' that generates html,
text, etc. for page navigation
SYNOPSIS
### 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',
} );
### 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',
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::Pageset's methods continue to function as normal.
METHODS
new()
`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.
html()
html( $link_format )
html( $link_format, $current_page_format )
my $text = $pager->html();
my $text = $pager->html( '%a' );
my $text = $pager->html( '%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 "...".
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 %]
<<
[% END %]
[% FOREACH num = [pager.first_page .. pager.last_page] %]
[% IF num == pager.current_page %][[% num %]]
[% ELSE %][[% num %]][% END %]
[% END %]
[% IF pager.current_page < pager.last_page %]
>>
[% 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.
link_format()
$pager->link_format( '%a' );
Accessor for the link_format setting.
current_page_format()
$pager->current_page_format->current_page_format => '[%a]' );
Accessor for the current_page_format setting.
TODO
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.
