Ace::Browser::SearchSubs - Subroutines for AceBrowser search scripts
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');
Ace::Browser::SearchSubs exports a set of constants and subroutines that are useful for creating AceBrowser search scripts.
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.
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.
- 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.
- 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');
Please report them.
