Ace::Browser::SearchSubs(3pm) User Contributed Perl Documentation Ace::Browser::SearchSubs(3pm)
NAME
Ace::Browser::SearchSubs - Subroutines for AceBrowser search scripts
SYNOPSIS
use Ace;
use Ace::Browser::AceSubs;
use Ace::Browser::SearchSubs;
use CGI qw(:standard);
my $form = p(start_form,
textfield(-name=>'query'),
end_form);
AceSearchTable('Search for stuff',$form);
...
my $query = param('query');
my $offset = AceSearchOffset;
my ($objects,$count) = do_search($query,$offset);
AceResultsTable($objects,$count,$offset,'Here are results');
DESCRIPTION
Ace::Browser::SearchSubs exports a set of constants and subroutines that are useful for creating AceBrowser search scripts.
CONSTANTS
This package exports the following constants:
MAXOBJECTS The maximum number of objects that can be displayed
per page.
SEARCH_ICON An icon to use for search links. This is deprecated.
Use Configuration->Search_icon instead.
FUNCTIONS
These functions are exported:
$offset = AceSearchOffset()
When the user is paging back and forth among a multi-page list of results, this function returns the index of the first item to
display.
AceSearchTable([{hash}],$title,@contents)
Given a title and the HTML contents, this formats the search into a table and gives it the background and foreground colors used
elsewhere for searches. The formatted search is then printed.
The HTML contents are usually a fill-out form. For convenience, you can provide the contents in multiple parts (lines or elements) and
they will be concatenated together.
If the first argument is a hashref, then its contents will be passed to start_form() to override the form arguments.
AceResultsTable($objects,$count,$offset,$title)
This subroutine formats the results of a search into a pageable list and prints out the resulting HTML. The following arguments are
required:
$objects An array reference containing the objects to place in the
table.
$count The total number of objects.
$offset The offset into the array, as returned by AceSearchOffset()
$title A title for the table.
The array reference should contain no more than MAXOBJECTS objects. The AceDB query should be arranged in such a way that this is the
case. A typical idiom is the following:
my $offset = AceSearchOffset();
my $query = param('query');
my $count;
my @objs = $db->fetch(-query=> $query,
-count => MAXOBJECTS,
-offset => $offset,
-total => $count
);
AceResultsTable(@objs,$count,$offset,'Here are the results');
BUGS
Please report them.
