NAME Data::Page - help when paging through sets of results SYNOPSIS use Data::Page; my $page = Data::Page->new($total_entries, $entries_per_page, $current_page); print " First page: ", $page->first_page, "\n"; print " Last page: ", $page->last_page, "\n"; print "First entry on page: ", $page->first, "\n"; print " Last entry on page: ", $page->last, "\n"; DESCRIPTION When searching through large amounts of data, it is often the case that a result set is returned that is larger than we want to display on one page. This results in wanting to page through various pages of data. The maths behind this is unfortunately fiddly, hence this module. The main concept is that you pass in the number of total entries, the number of entries per page, and the current page number. You can then call methods to find out how many pages of information there are, and what number the first and last entries on the current page really are. METHODS new This is the constructor. It currently takes two mandatory arguments, the total number of entries and the number of entries per page. It also optionally takes the current page number (which defaults to 1). my $page = Data::Page->new($total_entries, $entries_per_page, $current_page); my $page = Data::Page->new(134, 10); my $page = Data::Page->new(134, 10, 5); total_entries This method returns the total number of entries. print "Entries:", $page->total_entries, "\n"; entries_per_page This method returns the total number of entries per page. print "Per page:", $page->entries_per_page, "\n"; current_page This method returns the current page number. print "Page: ", $page->current_page, "\n"; first_page This method returns the first page. This is put in for reasons of symmetry with last_page, as it always returns 1. print "Pages range from: ", $page->first_page, "\n"; last_page This method returns the total number of pages of information. print "Pages range to: ", $page->last_page, "\n"; first This method returns the number of the first entry on the current page. print "Showing entries from: ", $page->first, "\n"; last This method returns the number of the last entry on the current page. print "Showing entries to: ", $page->last, "\n"; AUTHOR Based on code originally by Leo Lapworth , with many changes added by by Leon Brocard .
